how to use STM32WB5MMG in B-U585I-IOT02A as HC-05 replacement?

[Fguna.1]

Hi, I want to use B-U585I-IOT02A as a controller for mobile robot, I use a smartphone for the remote control. For now I am using HC-05 as the bluetooth interface because I can't find out how to program the STM32WB5MMG to act similar with HC-05. Can anyone give me any guide or reference how to do it? I just need it to work as the bluetooth interface to receive serial data and send it to the STM32U585.

And I use MITAppInventor 2 to create the smartphone software if anyone wondering.

Hello,

You can use BLE_AT_Client application on STM32U5 side available here:

https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/B-U585I-IOT02A/Applications/BLE/BLE_AT_Client

You can use BLE_AT_Server application on STM32WB5MMG side available here:

https://github.com/STMicroelectronics/STM32CubeWB/tree/master/Projects/P-NUCLEO-WB55.Nucleo/Applications/BLE/BLE_AT_Server

You can find information about AT command on this wiki page:
