I assume that you have not made any changes to the firmware of the Find me project. Please check the following points:
1. Check if you have followed the hardware design recommendations correctly from this document.
2. You can also refer the development kit schematics and check once. Please refer CY8CKIT-062 kit schematics from the link below:
The important points to be considered are the decoupling capacitors on the VCCD pin, VDDIO, VDDR pins.
If everything is correct and still you are facing the issue, please check the return of the API Cy_BLE_StackInit(&stackInitParam); and Cy_BLE_Start(NULL). Please update them in this thread.
Please ensure that you are using latest PDL (PDL 3.1.0).
