This project was to try LoraWAN network without the need of an STM32 onboard,
as a LoraWAN stack can fit inside the Arduino.
I first designed an Arduino Shield and it works well so I updated my previous NoteRF PCB to include Lora transceiver and some more features.
The code is compliant with LoraWAN specification V1.0, class A. It works with pre-provisioning and OTAA.
