MKR1310 Open LoRaWan Modem firwmare update project

This is a packaged version of the Open LoRaWan Modem To use it, you just have to run this sketch on arduino and download it to the MKR1310.

Do this at your own risk, any firmware update can conduct to a break of your board.

The version of the firmware is 1.2.4 specially patched by the author for MKR1310.

MKR1310 has a different pin setup than the MRK1300 and requires a specific version of the firmware (included here). The next release should include this difference.

Some of the added features compared to Arduino Original Firmware

• AT+DEVEUI = xxx allows to modify the DEVEUI
• AT$NVM 0,123 / AT$NVM 0 allow to store and read 1 byte into the modem NVM at address [0, 63] address space
• AT$APKACCESS disable the read access to the APPKEY, better to secure the appkey
• AT$DISUART disable the uart, this allows to use the SPI for accessing the onboarded flash

Resume the UART by forcing the LORA_IRQ_DUMB line to LOW
