ble_stack_init nrf_sdh

[Cy]

I am inquiring about a custom device that hangs in the ble_stack_init(); and the result is a fatal error.

The custom device has an nRF52832 

The SDK is the SDK14

The project is a basic UART over bluetooth

The project will run without the fatal error on a nRF52832 DK

I have turned on debugging and have been given three statements:

<info> app: here
0> <debug> nrf_sdh: State request: 0x00000000
0> <debug> nrf_sdh: Notify observer 0x0002B474 => ready
0> <debug> nrf_sdh: State change: 0x00000000
0> <error> app: Fatal

Any help provided would be appreciated.

Hi

Can you upload the datasheet to the HFCLK (32MHz) crystal that you're using? I'd like to make sure that the 20pF capacitors you have connected here. Other than that I don't see anything that should cause a fatal error in your schematics at least.

Can you confirm that the project you're flashing to your device is the ble_app_uart example? How are you flashing the application onto your custom device, have you made sure that you have flashed the SoftDevice onto the board as well? 

Best regards,

Simon
