A Python and wiringpi based LoRa receiver for RaspberryPi
This is a small receiver software tested with RaspberryPi 3 and the Adafruit RFM95W
The wiring is based on LoRasPI, but it should work with any RFM95.
Currently it uses continous RX mode, allows for crc validation and prints the packet unstructured to the console. There is no support for addressing or other advanced more features yet.

I took heavy inspiration from RadioHead, however i didn't like the lack of interrupt support.
This combined with a lack of crc validation, reservations against C++ and pure curiosity motivated me, to create another receiver implementation in Python.
