I am using a NUCLEO-WL55JC1 and the LoRaWAN_End_Node example. I want to add USART1 to the example, so that I can forward the UART data over LoRa. The problem is that the interrupts for USART1 never trigger if the LoRaWAN process is also running.

If I comment out "MX_LoRaWAN_Process();" in main, then the USART1 interrupts trigger as they normally would. Could anyone offer some advice of how to add USART1 to the example?Kind regards
