Hello ST Community,
I recently made PCB using STM32WB55CGU6 MCU. I used STM32WB-Dongle as reference and designed 4-layer PCB.
After board bring up and soldering I found that every peripherals of my board are working except Bluetooth.
I am using P2P-server application code and I see nothing on ST-ble mobile app.
Can anyone suggest how can I make Bluetooth working?
Thanks and Regards,
Nikunj Panchani

After so many trials and errors, I found that the external LSE was stuck due to the supercapacitor.
After removing the component LSE went well and the hardware worked.
