ble_app_uart system reset at nrf_sdh_enable_request()!

[Yogeshwaran]

Hi i was trying to add nrf calender part which i found in git hub for nrf52 chip with ble app uart example, but when i nrf_sdh_enable_request() called to initialize ble system reset is happening.

Is it because both uses XTAL CLK configuration? will the clock configuration cause issue? The error reported was 0x1001 and if anybody can give reference to how to add nrf_calendar with soft device example that would save little bit time in my development. 

Thanks in advance.

You cannot configure clock directly in your application when you are using softdevice. The error you get is 

#define NRF_ERROR_SDM_INCORRECT_INTERRUPT_CONFIGURATION (NRF_ERROR_SDM_BASE_NUM + 1)  ///< Incorrect interrupt configuration (can be caused by using illegal priority levels, or having enabled SoftDevice interrupts).

Let the softdevice configure the LFCLK when you configure nrf_sdh_enable_request. Move everything that needs the LFCLK to after you enable the softdevice and do not configure the XTAL CLK directly from your app.

Thanks and sorry for late reply. I made changes as you said and now it is working fine.
