STM32WB55 Nucleo --- working with debugger and not without

[SWenn.1]

Hello all....

Looking for some pointers. I have an application I created in CubeMX/IDE on a WB55 nucleo board. I am using nRF Connect app on my phone as the Client. When I run the nucleo server application with the debugger connected all seems to work fine, both BLE and application. That is to say the nRF Connect discovers the nucleo and I can read/write to nucleo. However when I disconnect the debugger and power the board via a power supply / battery or even re-plugging the usb power back onto the nucleo the nucleo (server) almost never shows up in the list of devices in the nRF Connect application.

With debugger disconnected:

I have verified power to the board and it is all good. I also (via a scope) see my application code running as expected via the Time Server. I use the word "almost" above because on two occasions I was able to power the boards and the app at the correct moment and I was connected and all looked good. I based my code on the BLE_Custom application. Can anyone give me some guidance as to what to look into??

Thanks

Hello Remy....

WOW!!!! That worked...I would have spent a career trying to find that one. Is there an ST location that lists bugs and fixes somewhere public? by the way I was running 1.12 CubeIDE and the change in the .id file was required there. Can you please give me a description of the problem that the "period (.) " in the file was creating?

Thank you very much for the insight
