RAK3172T TXCO configuration Issue

[HelgeSeidel]

I’m happy that the STM32LoRaWAN library V0.2.0 was released a couple of days ago.

I tried the new library with my RAK3172 evaluation board and everything worked as expected. On the evaluation board a RAK3172E module is installed and I did a full chip erase before I flashed my own file based on the basic example.

In parallel I have 25 nodes with a RAK3172T module installed. The RAK3172T module has an TXCO installed for a lower operation temperature and need a special configuration. I was not able to get the same program running on the RAK3172T module. The device will not connect to TTN.

I used Board “LoRa Boards” and the Board Part Number “RAK3172 Module”. STM32LoRaWAN library V0.2.0 and STM32RTC library 1.4 on Arduino 2.2.1.

I guess we need a new device for the RAK3172T module.

I changes the LoRaWAN definition LORAWAN_BOARD_HAS_TCXO in variant_RAK3172_MODULE.h from 0U to 1U and and everything is fine.

Hi @HelgeSeidel
This is not an issue. I guess you have to define new board variant or a derivative from the RAK3172 module added by one contributor:
