Besides the classic APRS on 2 m, same OMs experiment with off the shelf LoRa transceivers.


PlatformIO core

Most installation descriptions describe the installation using a full installation of PlatformIO with IDE. But, the installation is also possible on the command with just PlatformIO Core. Just follow one of their installation methods. For example:

wget https://raw.githubusercontent.com/platformio/platformio-core-installer/master/get-platformio.py -O get-platformio.py
python3 get-platformio.py

Installation on the tracker

After the installation of platform.io, we can directly call pio. Alternatively, you can add it to the PATH. The environment is specfied with -e. You can see the enviroments in the platformio.ini file.

~/.platformio/penv/bin/pio run -e ttgo-t-beam-v1 -t cleanall
~/.platformio/penv/bin/pio run -e ttgo-t-beam-v1 -t upload

The configuration must be modified in data/tracker.json before installation.

~/.platformio/penv/bin/pio run -e ttgo-t-beam-v1 -t buildfs
~/.platformio/penv/bin/pio run -e ttgo-t-beam-v1 -t uploadfs

Installation on the iGate

~/.platformio/penv/bin/pio run -e lora_board -t cleanall
~/.platformio/penv/bin/pio run -e lora_board -t upload

The configuration must be modified in data/is-cfg.json before installation.

~/.platformio/penv/bin/pio run -e lora_board -t buildfs
~/.platformio/penv/bin/pio run -e lora_board -t uploadfs


I modified the code to send proper APRS telemetry messages of type PRAM, UNIT, EQNS and T. You find this source code on GitHub.
