USB dongle BLE STM32WB55

[michaldunajski]

I have a problem with STM32WB55 USB dongle Nucleo. After adding some code (according to: AN5289 Building wireless applications with STM32WB series MCUs, https://stcommunity.st.com/t5/stm32-mcus/how-to-run-a-ble-p2p-server-simultaneously-with-usb-cdc-on/ta-p/49433, https://wiki.st.com/stm32mcu/wiki/Category:Bluetooth_Low_Energy, https://www.youtube.com/watch?v=7_wBH7mTQ2g&list=PLnMKNibPkDnG9JRe2fbOOpVpWY7E4WbJ-) Nucleo board randomly stops appearing in available Bluetooth device list after reattach to PC USB port. I have to then plug/unplug this device as many times as I will see device on Bluetooth device list. I enabled log tracing BT Application stack and the logs are the same with discoverable BT device on available BT device list and when the device is not discoverable (even if the App stack log says otherwise).

Log below.

I also upload to this case proof of that in some cases this device is discoverable, FUS info read via ST Link nad .ioc project file - maybe it can somehow help get information what peripherals I use.

Is there a way to somehow check why it is happening? Maybe combination of some registers?

Shall I upload something else to this case?
