Hello, I’m developing a LoRaWAN project and I intend to use the RAK3172.
In this project, I will program it using STM32CubeIDE and SWD.
I will also use UART1 for a GPS module, but I have a question regarding UART2. I saw that it is reserved for communication with the LoRaWAN module, but I would like to use it for printf debugging. Is that possible?
Welcome to the forum @samuellbs
The LoRa transceiver inside the STM32WLE5 is communicating over SPI, not over UART.
UART2 is used with our AT command firmware RUI3 to communicate with an external Host MCU.
If you are using STM32CubeIDE, you can do with UART2 whatever you want.
Thank you very much for the quick response, Beegee.
I will use this UART to be able to view it on the monitor then…
Have a great weekend!
