Debugging UART and BLE Advertising Issues on STM32WB05KZ (stm32cubewb0-v1-3-0)

[atuls2004]

I am currently working on BLE applications for a custom STM32WB05KZ board using the SDK stm32cubewb0-v1-3-0. In general, peripherals such as GPIO and UART are functioning correctly when running non-BLE examples provided in the SDK.

However, when I run BLE applications (such as Beacon, Server, or Client), I am unable to receive any logs over UART (configured on PB0 and PA1). I have verified that an LED, which is initialized prior to the BLE initialization in app_entry.c, operates correctly, indicating that the application is executing at least up to that point.

The main issues I am facing are:

• No log output is observed on the UART interface during BLE operation.

• The device does not appear to advertise(No address is visible: random or public), as it is not detected by the ST BLE Toolbox application.

I would appreciate any guidance or suggestions to help identify and resolve this issue.
