Hi there, I have an B-WL5M-SUBG1 evaluation board which uses the STM32WL5M module.I am having problems with the STM32 receiving a message I am sending it from my laptop via python. I connect between the stm32 and the laptop via an RS422/485 converter...

Hi Andrew, I’ll draw a schematic tomorrow. But my setup is as follows:I have the B-WL5M-SUBG1 powered by a 5V bench PSU.i connect the B-WL5M-SUBG1 to an MB1440B board to access the tx and rx pins easier. I connect the Tx and Rx pins to the T+ and T- ...

Ah thank you. I set up USART2 as Asynchronous, I guess RS485 is a different option. I’ll look at this tomorrow too. Thank you.
