This project is a quick start for the RAKwireless WisBlock RAK4631 LPWAN module. It gives the opportunity to test the LPWAN functionality without writing and flashing code.
It is a very simple firmware that provides an AT Command Interface over USB or BLE UART of the module. It is not optimized for low power consumption.
The LPWAN credentials are stored in the flash memory of the RAK4631 LPWAN module. The firmware is written using the Arduino framework, the source code is provided for both Arduino IDE and for PlatformIO. It uses the Nordic nRF52 boards package which needs to be patched with the RAK_Patch to support the RAK4631.
All AT commands are listed and explained in the AT-Command Manual.
