Ever since I built my RaspberryPi/SHARI AllStarLink node I’ve had to manage connecting/disconnecting to/from other nodes using the Allmon2 or Supermon web admin interfaces. These work fairly well albeit, a bit clunky and buggy. It’s impossible to use from a mobile device though and so I have to get my Macbook out each time I want to connect/disconnect nodes.
Being a Node-RED fanatic I decided that I should put something together that was more portable, mobile friendly and much easier to use. A simple user interface is all that is required and can be achieved very easily using the standard Node-RED dashboard nodes.
Initially I started investigating the Linux command-line interface for Asterisk, the VOIP system that underpins AllStarLink (ASL). I very quickly discovered that the ASL node can be very easily controlled directly from the command-line and that this would be an ideal interface to use to enable node management via a Node-RED dashboard.
In very little time at all I had an experimental control dashboard working with the ASL node and was able to connect/disconnect to/from a single node. All that was required now was to extend this so that I could connect to a number of nodes with nothing more than a push of a button.
Completed v1.0 AllStarLink Control Dashboard – Node-RED Flow
The resultant flow consists of 3 sections, Connect/Disconnect Main Flow, Manage Node Subflow and /var/log/asterisk/connectlog Subflow.
The Connect/Disconnect Main Flow handles all the input from the buttons on the dashboard and the communication to the underlying Asterisk VOIP system.
The button status is denoted by 3 colours, green (Ready to connect), orange (Transitioning to/from connect) and red (Connected). Each button is updated automatically by the button refresh function that is triggered every 2 seconds.
The Manage Node Subflow provides a simple interface to restart the Asterisk VOIP system, reboot the RaspberryPi and shutdown the RaspberryPi. The node status is automatically updated every 45 seconds and will show when the Asterisk subsystem is being restarted or the node is being rebooted or shutdown.
Finally the var/log/asterisk/connectlog Subflow monitors the Asterisk connectlog looking for connect/disconnect messages so that it can signal to update each button status.
Node-RED AllStarLink Dashboard
Each section of the dashboard can be collapsed/opened by touching/clicking the little blue arrows on the right of the dashboard. The dashboard works fine on Android, iOS, Windows, MacOS and Linux.
If you’re not familiar with Node-RED and haven’t yet installed it to your PC, take a look at the Node-RED Getting Started Page. The information takes you through installing Node-RED onto a multitude of devices including PC and RaspberryPi devices.
Once you have Node-RED installed all you need to do is download the AllStarLink Control Dashboard Flow and import it to your Node-RED flow editor.
Once downloaded, select Import from the burger menu icon on the right-hand side of the flow editor as shown below and import the flow file.
Node-RED Flow Editor import Menu Item
Once imported you will find that some of the nodes in the flow are not available. This is because you need to add them to the flow editor palette before being able to deploy the flow.
Drop down the same menu as shown above but, this time select Manage Palette. This will open another window where you will need to select the Install tab as shown below.
Node-RED Flow Editor Palette Install Tab
You need to install two node sets to complete the flow, node-red-contrib-bigssh and node-red-dashboard. Type in the name of each package one at a time in the search bar and then click the Install button. Once the two packages are installed you then need to configure the credentials for logging into your RaspberryPi. This is simply done by double clicking the blue Send Command to ASL node at the top of the main flow and then clicking the Pencil button at the end of the Credentials field. This will open another window where you will need to type in the IP Address of your ASL RaspberryPi into the Host field, then enter 22 into the port field, add repeater into the Username field (repeater is the default username, if you have changed this then you will need to add the new username name in instead) and then the password associated with the repeater login into the Password field. (Normally allstarlink)
Once this is done, do the same on the other blue nodes, namely “Get Node Uptime“, “Command =>> RaspberryPi” and “Tail ConnectLog”.
The final thing to setup is the dashboard size. Click on the downward pointing triangle at the top right of the menu bar (under the burger menu) and select dashboard. Check that the sizes are set the same as in the image below. For some reason, these settings aren’t always imported (Possible bug?) so, if your dashboard layout isn’t like shown above it will be because these settings failed to import.
ASL Dashboard Settings
You are now ready to deploy your AllStarLink Control Dashboard! Press the red Deploy button at the top of the flow editor window.
Finally, if you want to change the nodes that each button connects/disconnects you will need to edit the set flow var’s function at the top of the main flow. All you will need to do is replace the existing node numbers taking care not to alter the rest of the code in any way otherwise, it could stop the flow from working.
Once you’ve edited the node numbers, double click on the associated button node and change its Label to show the new node name.
Once your changes are complete, Deploy the flow again and your changes will be live.
This is version 1 of the ASL Dashboard, I already have ideas for version 2 that will also have the ability to enter a node number into a field and connect to it without the need to program it into a button.
Coding of version 1 of the AllStarLink Dashboard is now complete and in the final testing phase. Below is a short video clip showing some of the functionality.
The Node-RED flow for the web app is pretty compact and easy to alter should I add more functionality in the future.
M0AWS Node-RED flow for the AllStarLink Node Dashboard
The dashboard is designed such that it’ll display nicely on mobile phones, tablets and desktop computers so, I can easily control my AllStarLink SHARI node from any of my devices around the house.
I’ll put together a more detailed article on the web app once testing is complete and it’s ready to be released into the wild.
This is more of an aide memoire for myself more than anything but, may be useful to anyone who is using a SHARI powered AllStarLink node.
Out the box the SHARI build as documented here and here uses node numbers in announcements when connecting/disconnecting. The information in this article will change this so that the announcements use the node callsigns instead of node numbers.
As user repeater, login to the RaspberryPi that the SHARI is connected too via SSH and run the following commands:
1: Edit /usr/sbin/write-node-callsigns and change SRCDIR to point to /var/www/html/allmon2
# 28/08/24 - M0AWS - Changed path to point to allmon2
##SRCDIR=/var/www/html/allmon
SRCDIR=/var/www/html/allmon2
2: Copy the astb.txt file into the necessary directory:
Over the last couple of days in-between doing other things I’ve been writing and testing a BASH shell script that will completely configure a fully working AllStarLink node.
M0AWS – Coding the BASH script for the automated AllStarLink installation
To use the script you must already have your RaspberryPi (preferably a Pi 3b) connected to your LAN with full internet access using the Raspbian based version of the AllStarLink software downloadable from here.
The specific version I use is:
asl-2.0.0-beta.6-kc1kcc-20210324-rpi-armhf
I have tested the BASH script using this specific version of O/S only.
Once your RaspberryPi 3b is up and running, has full internet access and is accessible on your local LAN, using SSH login in as the user ‘repeater‘ using the password ‘allstarlink‘.
It’s important you only use this login to configure the node as this is the user the script is expecting to be run by. You must login via SSH as the SHARI device needs to be connected to the RaspberryPi 3b and you won’t be able to connect a keyboard and mouse at the same time. (If you are using two USB cables for the SHARI device then you can use a keyboard and mouse along with a monitor attached to your RaspberryPi instead of using SSH).
Once logged in as user repeater run the following wget command to download the zipped install script:
You are now ready to build your AllStarLink node. Before you run the script make sure you have your node number and node secret to hand. These are obtained from the AllStarLink portal.
Once you’ve got all your node information you can run the script using the following command:
./install.sh
The script will now take you through the full process of updating the operating system as necessary, installing all the required packages and software. It will then reboot the RaspberryPi and you will need to login and run the script a second time using the command above.
On the second run the script will install some python specific software, ask you to enter your callsign, node number and node secret and will then configure your node. The last thing it does is configure the Allmon2 and Supermon Web Admin websites. During this process it will ask you to enter a password twice for the Admin user for the two websites, make sure you make a note of this password as you will need it to login and control your node.
Once the node is configured it will be rebooted and you will then be able to connect to your node using your favourite web browser and the user admin and the password you set above.
To access the Allmon2 web-admin system use the following URL:
For those of you who prefer Supermon you an use the following URL:
http://your-RaspberryPi-IP-Address/supermon
M0AWS – Supermon Web Admin view
I have also pre-populated the Favorites button with a list of nodes that I use often. You can easily change these entries by editing the favorites.ini file in the /var/www/html/supermon directory as user root.
M0AWS – Supermon pre-populated Favourites drop down list
When you first login to your node via your web browser you’ll notice that it says your node isn’t in the database. You can update the database by using the following URL in your web browser:
We’ve recently added a new room to the Matrix HAM Radio Space for Digital Voice modes as this was an area of interest that didn’t really fit into any of the other rooms.
The new Digital Voice room has attracted a lot of attention from members, with a lot of the focus being on the AllStarLink system. Michael, DK1MI built an AllStarLink node in the cloud for us all to use for Matrix Nets and so I decided I had to get in on the fun.

The two USB connectors on the SHARI device are position such that they plug into two of the available 4 USB ports on the RaspberryPi without the need for cables. This keeps the whole solution together in one neat package.
Before you start you will need to obtain a node number and secret (password) from the AllStarLink Portal. To get this you will need to provide proof to the AllStarLink administrators that you are a licensed Amateur Radio (HAM) operator. This is done by uploading a copy of the first page of your HAM licence to the website for the admin team to check. This can take 24hrs to be completed so make sure you get this all done before trying to build your node. You cannot build a node successfully without a node number and secret.
Of course you will also need a transceiver that can operate on the 438.800Mhz frequency or other frequency of your choice on the 2m or 70cm HAM band.
You will also need to open port 4569 on your internet router and setup port forwarding to the IP Address that you will be using on your RaspberryPi node. It’s important to use a static IP Address on your RaspberryPi.
There are quite a few different Linux based operating system (O/S) images that are available for the RaspberryPi devices that have been specifically tailored for the AllStarLink node and include all the necessary software and library packages out the box.
Once downloaded you need to burn the ISO image onto a suitable SD card for your RaspberryPi. I use BalenaEtcher as it’s extremely quick and reliable at burning ISO images to SD cards.
Of course if you are a hardline Linux command line junkie you can always use dd to create the SD card.
Once you’ve got your O/S onto your SD card, slot it into your RaspberryPi making sure your SHARI device is connected to the two USB ports and then power it up. Make sure you have a good PSU for the RaspberryPi as the two devices together draw around 3A of current during the transmit cycle. (I use a 3.6A PSU from Amazon).
The default login for the Raspbian O/S is shown below. Login via SSH and configure your RaspberryPi for your local network. It’s important to use a static IP Address configured either directly on the RaspberryPi or via DHCP in your router.
Next you need to change directory into the asterisk config file directory using the command shown below:
cd /etc/asterisk
In this directory you will find all the default config files that come as part of the distro. For this build we’re not going to use them and so we need to move them out of the way ready for a set of config files that have already been configured correctly.
Using the following commands create a new directory, move into that new directory and then move all the unwanted configuration files into it:
mkdir ORIGINAL-CONF-FILES
cd ./ORIGINAL-CONF-FILES
mv ../*.conf ./
ls -la
cd ../
You should now be back in the /etc/asterisk directory which will now be empty apart from the custom directory which we left in place.
You now need to copy the correctly configured configuration files into the /etc/asterisk directory. Start by downloading the zip file containing the new configuration files
Once downloaded, copy the .zip file into the repeater users home directory (/home/repeater) using either scp on the Linux command line or if using Windows you can use the FileZilla Client in SFTP mode using the login details above.
Once you have the .zip file in the repeater user’s home directory you need to copy the file into the /etc/asterisk directory as user root:
Next as user root, change directory into the /etc/asterisk directory and unzip the .zip file:
cd /etc/asterisk
unzip ./AllStarLink-Config-v3.zip
Once the file is unzipped you will have a directory called AllStarLink-Config in the /etc/asterisk directory. You now need to cd into the directory, copy all the files out of it into the /etc/asterisk directory leaving a copy in the AllStarLink-Config directory for future reference:
cd /etc/asterisk/AllStarLink-Config
cp ./* /etc/asterisk
cd /etc/asterisk
You now need to move a couple of files into the repeater users home directory using the following commands:
The gpioBASH script and configuration details were supplied by Mark, G1INU in the Digital Voice room on the Matrix. It adds the COS light functionality to the setup. The COS light will now light every time the SA818 hears RF on the input.
The next thing you need to do is configure the SA818 radio device in the SHARI. The script I used was originally from https://wiki.fm-funknetz.de/doku.php?id=fm-funknetz:technik:shari-sa818 all I’ve done is change the entries to switch off CTCSS and change the frequency to 438.800Mhz. Configuring the SA818 is done by running the SA818-running.pyPython programme that you moved into the repeater user home directory. Making sure you are still user root, run the following commands:
cd /home/repeater
./SA818-running.py
At this point your SHARI SA818 device will be configured to operate on 438.800Mhz and CTCSS will be disabled.
If you want to change the frequency or enable and set a CTCSS tone to access the node you will need to edit the Python programme using your favourite text editor and change the entries accordingly. Once changed rerun the program as shown above and your SHARI will be reconfigured to your new settings.
Next you need to move the allmon.ini.php file into the correct directory so that it enables access to the Allstar Monitor web page on the device so that you can manage connecting/disconnecting nodes. Use the following commands as user root to achieve this:
The allmon.ini.php file needs to have your node name entered into it to work correctly. As user root, change directory and edit the file using your favourite editor.
cd /var/www/html/allmon2
Using your text editor, search for the line starting [XXXXX] and change the XXXXX to your node number. Save the change and exit the file.
At this point you are almost complete, all that is left to do is add your node number and node secret into the appropriate configuration files in the /etc/asterisk directory.
Since I am a Linux command line junkie I use vi to edit all the configuration files on the command line as user root, but you can use any editor of your choice.
cd /etc/asterisk
Start with the extensions.conf file. Search for the line starting with NODE = and delete the XXXXX entry and insert your node number. Save the file and exit it.
Next you need to edit the iax.conf file. This time search for the line starting with register= and change the XXXXX for your node number and the YYYYYYYYYYYY for your node secret. Be careful not to accidentally delete any other characters in the lines otherwise it will corrupt the configuration file.
In the same file search for the two lines that start with secret = and change the YYYYYYYYYYYY for your node secret. Once you have changed both of the secret entries, save and exit the file.
The final file to edit is the rpt.conf file. Once again open the file using your favourite editor and search for the line starting with XXXXX = radio@127.0.0.1:4569/XXXXX, change the XXXXX entries for your node number making sure not to delete any other characters next to the XXXXX entries.
Further down in the same file there is a line that starts with [XXXXX], once again change the XXXXX for your node number making sure to keep the square brackets at each end of the node number as you edit it.
Finally move down to the very bottom of the file and find the two lines that start with /home/repeater/gpio, once again change the XXXXX entries for your node number.
The final thing to change in the rpt.conf file is to replace my callsign with your own callsign so that the node identifies itself correctly. Scroll through the file until you find the two lines shown below, delete M0AWS and add your own callsign instead making sure you keep all the spaces between words as shown below.
idrecording = |i DE M0AWS
idtalkover = |i DE M0AWS
Once this is done, save and exit the file. At this point your node should be fully configured and will only require a reboot to get it working.
As user root, reboot your raspi using the reboot command.
reboot
Once your raspi comes back online, login using SSH as user repeater and then become root user using the sudo command detailed above.
You now need to create the admin user password for the Allstar Monitor web page on the device. This is done using the following commands as user root:
cd /var/www/html/allmon2
htpasswd -c .htpasswd admin
You will be asked to enter a password twice for the admin user. Make sure you make a note of this user/password as you will need it to login to the web page.
Finally check that the controlpanel.ini.php file is in the /var/www/html/allmon2 directory:
ls -la /var/www/html/allmon2/controlpanel.ini.php
If the file isn’t shown in the directory, enter the following commands to create the file in the correct place as user root and then exit the SSH session:
cd /var/www/html/allmon2
cp ./controlpanel.ini.txt ./controlpanel.ini.php
cd
exit
Once this is done your configuration is complete, logout from the terminal session by entering exit once more and your SSH session will terminate.
Using your favourite web browser enter the IP Address of your raspi into the URL bar as shown below:
http://<Your-Raspi-IP>/allmon2
Note: remove the <> from the URL once you have entered the required information.
Once this is done you should be presented with your node control panel as shown below.
First visit to the AllStar Monitor Web Page
Login using Admin and the password you set above and you are now ready to start using your node.
It’s a good idea to connect to node 55553 which is a parrot test node to check your audio levels. You can do this by entering the node into the field at the top left and pressing the connect button.
M0AWS AllStarLink Node 61928 connected to 55553 Parrot
Once connected, tune your radio to 438.800Mhz FM and transmit a test message using your callsign and test123, or something similar. The parrot will then play your recording back to you so that you can hear how you sound. It will also comment on your audio level as to whether it is OK or not.
You are now connected to AllStarLink network and have the world at your finger tips. Below is a small list of nodes in the UK, Australia and America to get you started chatting with other HAMs via your node.

Thanks to Michael, DK1MI for building and hosting the Matrix HAM Radio Space AllStarLink Node (57881) and getting us all started in the world of AllStarLink!
We hope to be having regular Matrix Net’s on the node soon for all Matrix members and visitors. We’ll organise days/times via the Digital Voice room.
I’ve got a couple of old RaspberryPi computers on the shelf in the shack and so decided it was time for me to put one of them to good use. The first model on the shelf is the oldest and is one of the very first RaspberryPi 1 computers that was released. (It’s the one with the yellow analog video signal output on the board!). This particular model is extremely slow but, I hang onto it just as a reminder of the first SBC in the line.
The second one is a RaspberryPi 2, a quad core machine that is only slightly faster than the first model but, it’s powerful enough to run HAM Clock.
It didn’t take long to install a vanilla Raspbian Desktop O/S and get it configured on the local LAN. I installed a few packages that I like to have available on all my Linux machines and then started on the HAM Clock install.
The first thing I needed to do was install the X11 development library that is required to compile the HAM Clock binary. To do this, open a terminal and enter the command below to install the package.
sudo apt install libx11-dev
You will need to type in your password to obtain root privileges to complete the installation process and then wait for the package to be installed.
The HAM Clock source code is available from the HAM Clock Website under the Download tab in .zip format. Once downloaded unzip the file and change directory into the ESPHamClock folder ready to compile the code.
cd ~/Downloads/ESPHamClock
Once in the ESPHamClock directory you can run a command to get details on how to compile the source code.
make help
This will check your system to see what screen resolutions are available and then list out the options available to you for compiling the code as shown below.
The following targets are available (as appropriate for your system)
hamclock-800x480 X11 GUI desktop version, AKA hamclock
hamclock-1600x960 X11 GUI desktop version, larger, AKA hamclock-big
hamclock-2400x1440 X11 GUI desktop version, larger yet
hamclock-3200x1920 X11 GUI desktop version, huge
hamclock-web-800x480 web server only (no display)
hamclock-web-1600x960 web server only (no display), larger
hamclock-web-2400x1440 web server only (no display), larger yet
hamclock-web-3200x1920 web server only (no display), huge
hamclock-fb0-800x480 RPi stand-alone /dev/fb0, AKA hamclock-fb0-small
hamclock-fb0-1600x960 RPi stand-alone /dev/fb0, larger, AKA hamclock-fb0
hamclock-fb0-2400x1440 RPi stand-alone /dev/fb0, larger yet
hamclock-fb0-3200x1920 RPi stand-alone /dev/fb0, huge
For my system 1600×960 was the best option and so I compiled the code using the command as follows.
make hamclock-1600x960
It’s no surprise that it takes a while to compile the code on such a low powered device. I can’t tell you how long exactly as I went and made a brew and did a few other things whilst it was running but, it took a while!
Once the compilation was complete you then need to install the application to your desktop environment and move the binary to the correct directory.
make install
Once the install is complete there should be an icon on the GUI desktop to start the app. If like mine it didn’t create the icon then you can start the HAM Clock by using the following command in the terminal.
/usr/local/bin/hamclock &
The first time you start the app you’ll need to enter your station information, callsign, location etc and then select the settings you want to use. There are 4 pages of options for configuring the app all of which are described in the user documentation.
M0AWS – HAM Clock running on RaspberryPi Computer
Once the configuration is complete the map will populate with the default panels and data. I tailored my panels to show the items of interest to me namely, POTA, SOTA, International Beacon Project and the ISS space station track. I was hoping to be able to display more than one satellite at a time on the map however, the interface only allows for one bird to be tracked at a time.
You can access the HAM Clock from another computer using a web browser pointed at your RaspberryPi on your local LAN using either the IP address or the hostname of the device.
http://<hostname>:8081/live.html
or
http://<ip-address>:8081/live.html
You can also control the HAM Clock remotely via web browser using a set of web commands that are detailed on port 8080 of the device.
http://<hostname or ip-address>:8080/

This is a great addition to any HAM shack especially if, like me you have an old HDTV on the wall of the shack that is crying out to display something useful.
The loading of the Meshtastic firmware on the Heltec ESP32 v3 devices is really simple if done via a Linux PC/RaspberryPi. There are of course other ways to load the firmware using a web browser that supports USB/Serial devices and this method is preferred by many however, being a Linux command line junkie I far prefer the simplicity of using the Linux command line to do the job.
So, how much experience with the Linux command line do you need?
In all honesty none at all. If you know how to use copy and paste then all you have to do is follow the simple steps I’ve detailed below. In reality it will only take a few minutes to do so, don’t be put off by the long article, I’ve just tried to cover everything and provide screen shots along the way.
To get started fire up your Linux PC/RaspberryPi and get yourself to the desktop. Next you will need to open a Linux command line terminal. This is often just called “Terminal” on most Linux desktop installations.
The first thing you need to do is check to see if you have python3 installed. This is done using the following command:
python3 --version
Running the above command you should see a result something like what is shown below.
Python3 command showing installed version
Next we need to check if pip3 is installed using the following command:
pip3 --version
If pip3 is installed then you should get a result similar to that shown below.
Pip3 command showing installed version
If your computer doesn’t have Python3 or Pip3 installed they can be easily installed from the command line. To install Python3 enter the following command into your terminal:
sudo apt install python3
You will be asked to enter your login password and then the installation will begin. You should see output in your terminal similar to that shown below.
Installing python3
To install Pip3 enter the following command into your terminal:
sudo apt-get install python3-pip
This will detail a long list of packages that will be installed on your computer, Enter Y to answer Yes and let the packages install.
M0AWS – Installing Pip3
You will see many messages scroll up the terminal screen such as getting, selecting, preparing, unpacking and setting up, this is all normal.
Once Pip3 is installed you should be dropped back at the command line with a terminal screen that looks something like the one below.
M0AWS – Pip3 install complete
At this point you will now have Python3 and Pip3 available on your computer.
You are now ready to install the tool we are going to use to check your Meshtastic device is connected to your PC and install the firmware to it. (Do not connect your Meshtastic device to your PC just yet!)
Run the following command in your terminal to install the ESP Tool:
pip3 install --upgrade esptool
You will see an output from the installation process similar to that shown below.
M0AWS – Installing the ESP Tool
Now that we have the ESP tool installed plug your Meshtastic device into your USB port on your computer and then run the following command to interrogate the device to find out what kind of device it is.
esptool chip_id
You should see the information about your device that looks similar to that shown below. This information should confirm the device type (ESP32) and which USB port it is connected on (/dev/tty/USB0).
M0AWS – Expected output from the ESPTool command showing device information
Once you have this information you will need to download the firmware for your device from Github using the following URL:
https://github.com/meshtastic/firmware/releases
At the time of writing this I downloaded and used the v2.2.22.404d firmware which I have found to be extremely reliable.
In your terminal you now need to change directory (cd) into the Downloads directory where your downloaded firmware should be. (If you downloaded your firmware into another directory then you will need to cd into that directory). Use the following command to change directory into the Downloads directory.
cd ~/Downloads
Now we need to find the filename of the firmware we have just downloaded, we can use the list directory contents command to find the file using the simple command below.
ls -la firm*.zip
M0AWS – List firmware file name from the Linux command line
In the screenshot above we can see that the filename is called firmware-2.2.22.404d0dd.zip. We now need to unzip the file using the unzip command.
unzip firmware-2.2.22.404d0dd.zip
You’ll see lots of output from the unzip command about inflating files etc, this is normal.
Once the file has been unzipped you are ready to load the firmware onto your Heltec device. First you need to find the .bin file for your Heltec device. Use the following ls command to list the files available.
ls -la firmware-heltec*
This will list out all the firmware file options for the Heltec device as shown below.
M0AWS – List of Heltec firmware files
The file you need to use for a new firmware installation on a Heltec v3 device is firmware-heltec-v3-2.2.22.404d0dd.bin. (If you downloaded a different version then the version number in the file will be different).
Using the filename you found above enter the following command into your terminal.
This will now clear down your Heltec device and will load the Meshtastic firmware. This will take a little time especially on slower computers like the RaspberryPi so, just let it run until it finishes. Do not interrupt the process whilst it is running.
Installing the Meshtastic firmware onto my Heltec ESP32 v3 using the Python command line tool
Once the firmware is loaded the Heltec device will reboot and you will see the Meshtastic banner on the OLED screen. Your device is now ready for configuration.
Now that you have Python3 and Pip3 installed you can load the firmware onto other devices just by downloading the firmware and then running the device-install.sh script file, you won’t need to install Python3 or Pip3 again.
If you want to update your device in the future to a newer version of the firmware then just use the update script and update binary file as shown below.
