.NET nanoFramework RAK2305 – RAK3172 Library Usage

Posted on by

This post covers the usage of my RAK3172LoRaWAN-NetNF library with a RAK3205 WisBlock Wifi Interface Module on a RAK3172 Evaluation Board.

The first time the RAK3172LoRaWANDeviceClient is run the following preprocessor directives may need to be defined to configure the RAK3172 module.

//---------------------------------------------------------------------------------
//#define ST_STM32F769I_DISCOVERY      // nanoff --target ST_STM32F769I_DISCOVERY --update 
//#define  SPARKFUN_ESP32_THING_PLUS  // nanoff --platform esp32 --serialport COM4 --update
//#define RAK_WISBLOCK_RAK2305 // nanoff --update --target ESP32_PSRAM_REV0 --serialport COM4
#define DEVICE_DEVEUI_SET
//#define FACTORY_RESET
//#define PAYLOAD_BCD
#define PAYLOAD_BYTES
#define OTAA
//#define ABP
//#define CONFIRMED
#define UNCONFIRMED
#define REGION_SET
#define ADR_SET
//#define SLEEP
namespace devMobile.IoT.LoRaWAN

Once the RAK3172 Module is the RAK3172LoRaWANDeviceClient can be run with only PAYLOAD_BCD or PAYLOAD_BYTES defined

//---------------------------------------------------------------------------------
//#define ST_STM32F769I_DISCOVERY      // nanoff --target ST_STM32F769I_DISCOVERY --update 
//#define  SPARKFUN_ESP32_THING_PLUS  // nanoff --platform esp32 --serialport COM4 --update
//#define RAK_WISBLOCK_RAK2305 // nanoff --update --target ESP32_PSRAM_REV0 --serialport COM4
//#define DEVICE_DEVEUI_SET
//#define FACTORY_RESET
//#define PAYLOAD_BCD
#define PAYLOAD_BYTES
//#define OTAA
//#define ABP
//#define CONFIRMED
//#define UNCONFIRMED
//#define REGION_SET
//#define ADR_SET
//#define SLEEP
namespace devMobile.IoT.LoRaWAN

When I initially deployed ran the RAK3172LoRaWANDeviceClient the RAK3172LoRaWAN-NetNF library crashed in the OtaaInitialise method. I think this was caused by the RAKwireless Unified Interface V3(RUIV3) “AT+NWM=1” command rebooting the RAK3172 Module. 

// Set the Working mode to LoRaWAN, not/never going todo P2P with this library.
#if DIAGNOSTICS
Debug.WriteLine($" {DateTime.UtcNow:hh:mm:ss} AT+NWM=1");
#endif
Result result = SendCommand("Current Work Mode: LoRaWAN.", "AT+NWM=1", CommandTimeoutDefault);
if (result != Result.Success)
{
#if DIAGNOSTICS
	Debug.WriteLine($" {DateTime.UtcNow:hh:mm:ss} AT+NWM=1 failed {result}");
#endif
	return result;
}

I think it would be reasonable to assume that the device is in the correct mode (the default after a reset to factory) on startup so I removed the LoRa® network work mode configuration code.
