BLE_AT_CLIENT on B-U585-IOT02A – AT+BLE_SVC=1 does not appear despite WB5M update

Delta1
Associate II

Hello everyone,

I am currently working with the BLE_AT_CLIENT example on the B-U585-IOT02A and have previously updated the integrated STM32WB5M according to the instructions in readme.md. The start screen of the example appears correctly (screenshot: BLE.png).

However, a problem occurs which, according to this article https://mind.be/blog/using-the-bluetooth-stack-on-the-b-u585i-iot02a-board/ should occur immediately at start-up and independently of a BLE connection:

The command TX: AT+BLE_SVC=1 does not appear for me.

Normally, this command should be sent automatically immediately after TX: AT. However, only TX: AT is displayed on my device, and then nothing else happens.

Question for the community:

Is anyone familiar with this behaviour or know what could be causing the example to stop at initialisation and prevent AT+BLE_SVC=1 from being sent in the first place?

I would be very grateful for any tips on diagnosis or possible pitfalls.

Many thanks!
