I am not at home. I’ll take a look if I can share that with you. De nada. Abraço, Rodrigo

No, I haven't. Can you share a piece of code of how to do this? Obrigado Rodrigo!

I am always using a blocking way to write and a non-blocking way to read. Have you tried?

Hi Rodrigo, Yes the pins are okay. I can confirm the STM32 is sending a testing message (I connected the sending UART to my computer and read the input). Looks like the code to read the response is no

Gustavo, Are you sure the pins are setup ok? You can try to use a ftdi connector to be sure. Do you have an dts overlay? Best regards, Rodrigo

Thank you Stefan, I'll take a look. I'll share here the simple code I'm doing but so far it is not working. The pins PA9 and PA10 of my STM32 are connected to an adapter to serial port (TX->RX, RX->TX

Hey Gustavo, I had the same problem some moths ago. Some help to get into it: 1.) check how uarts work in ZephyrOS(poll/interrupt driven) https://github.com/zephyrproject-rtos/zephyr/tree/master/tests
