Unable to setup UART communication between Arduino nano and STEVAL-ESC002V1

[shashank7]

Hello everyone,
I’m trying to communicate between an Arduino Nano and the STEVAL-ESC002V1 board via UART, but I’m unable to get any proper response or control signal exchange. I’ve configured both devices at 115200 baud rate, but communication doesn’t seem to work.

 Any guidance or example code would be really helpful.

Hello @shashank7,

Did you review chapter 27. Universal synchronous/asynchronous receiver transmitter (USART/UART), of the STM32F0 Reference manual?
