LoRa / Kiss scripts to use a LoRa Modem with the ax25 tools / packet radio

This python script creates a virtual serial port (/dev/lora0) which can be used with the ax25 librarys to use packet radio over LoRa-Modems which are connected via SPI.

Usage

You need to start the script as root (or with root rights (sudo)), otherwise the script can't create the lora device under /dev.

config

Copy the cfg-file to /etc and change the settings to match your system (Hardware connection, Frequency and LoRa settings)

Start the script:

sudo python3 main.py

If the script starts and creates the lora0 device, create an ax25 port:

You need to create an entry in /etc/ax25/axports:

lora 9600 200 2 Packet over LoRa

Keep in mind, that the LoRa Modems can't send packets > 255 bytes, I limited it to 250 and discarded the initial plan to use the KISS protocoll (the data is already sent in packets)

start

Open another terminal and use kissattach to attach the modem:

sudo kissattach /dev/lora0 lora

Now you can start linpac:

sudo linpac

service

To start the script a service, you can copy the .service file to the systemd services and start it over systemd...

compile

This script uses a modified version of PyLora (https://github.com/Inteform/PyLora), I attached it in the PyLora.7z File, check instructions on the original page to build and install the library...
