How to send AT commands through UART on B-U585I-IOT02A?

Hello!

I have a question - I'm working on interfacing with the STM32WB5M module on the B-U585I-IOT02A. From what I understand, the STM32WB5M module is already flashed with an example for AT commands (in the STM32Cube_FW_WB_V1.13.3/Projects/P-NUCLEO-WB55.Nucleo/Applications/BLE/BLE_MultiAppAt).

I was hoping to be able to create a STM32 project for the B-U585I-IOT02A board without flashing anything to the STM32WB5M module. For now, I just wanted to be able to send an AT command according to the AN5379 application notes and receive some sort of info back from the module. If there is a way to do this, or if I have some conceptual error, please let me know!

Thank you,

Jake U.

AT Commands are just text strings.

The important thing to remember about AT Commands is that you need to pay attention to the responses to the commands you send - don't send the next command until the device has confirmed that it has completed the previous one.

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
