Try using this debug method to finc which line is causing the error.

I found some more description on nrf)pwr_mgmt_init(): Depending on configuration, this function sets SEVONPEND in System Control Block (SCB). This operation is unsafe with the SoftDevice from interrupt priority higher than SVC. AND #define POWER_CONFIG_IRQ_PRIORITY 7 at sdk_config.h file.

Does it cause the error? How can I find where and which line the error happened?

Thank you.

Thank again. faced the next "fatal error". this is the infinitive loop:`for (;;) {

    ///---------SAADC----------
  //*
    if(m_saadc_calibrate == true)
    {
        NRF_LOG_INFO("SAADC calibration starting...  \r\n");    //Print on UART
        while(nrf_drv_saadc_calibrate_offset() != NRF_SUCCESS); //Trigger calibration task
        m_saadc_calibrate = false;
    }
    //*/
    nrf_pwr_mgmt_run();
    NRF_LOG_FLUSH();
  
    ////---------SAADC----------
      //Leila, commented if cluase, 170626

// if (NRF_LOG_PROCESS() == false) // { // power_manage(); // } }` It seems at the end power_manage() and nrf_pwr_mgmt_run() do the same. So I commented power_manage(). but still face fatal error which I can not understand where and why.

Could you please help?

Check the API documentation. This error means that the softdevice have been enabled before nrf_drv_power_init is called:

NRF_ERROR_INVALID_STATE: Power driver has to be enabled before SoftDevice.

It was the solution, but after some second I saw fatal error again. I activated again the lines which I previously commented them (just to check if they were mandatory for the rest of code) and now get a fatal error form err_code = nrf_drv_power_init(NULL); as it gets back NRF_ERROR_INVALID_STATE.

could you please help me?

Yes, the softdevice use TIMER0 peripheral and will block access to this for the application. You need to enable another TIMER in sdk_config.h and initialize the timer using NRF_DRV_TIMER_INSTANCE(1);.

Thank you. The problem is solved. Another question regarding to add saadc sample code to ble_blinky; do they have the same resource? I mean they both use the same timer or so on?

Because finally I could Make it without any errors but doesn't work efficiently. It stocks at saadc_sampling_event_init() function and get me back ":ERROE:Fatal" on serial port.

int main(void)
{
    // Initialize.
    leds_init();
    timers_init();
    log_init();
    buttons_init();
    ble_stack_init();
    gap_params_init();
    gatt_init();
    services_init();
    advertising_init();
    conn_params_init();
      //*
    //---------SAADC----------
    //uint32_t err_code;
//    err_code = nrf_drv_power_init(NULL);
//    APP_ERROR_CHECK(err_code);

//    ret_code_t ret_code = nrf_pwr_mgmt_init();
//    APP_ERROR_CHECK(ret_code);

    NRF_LOG_INFO("SAADC HAL simple example.\r\n");
    saadc_init();
    saadc_sampling_event_init();
    saadc_sampling_event_enable();
    ////---------SAADC----------
    //*/
    // Start execution.
    NRF_LOG_INFO("Blinky BLE_ADC example started.\r\n");
    advertising_start();

    // Enter main loop.
    for (;;)
    {
      
        ///---------SAADC----------
      //*
        if(m_saadc_calibrate == true)
        {
            NRF_LOG_INFO("SAADC calibration starting...  \r\n");    //Print on UART
            while(nrf_drv_saadc_calibrate_offset() != NRF_SUCCESS); //Trigger calibration task
            m_saadc_calibrate = false;
        }
        //*/
//        nrf_pwr_mgmt_run();
//        NRF_LOG_FLUSH();
      
        ////---------SAADC----------
        
        if (NRF_LOG_PROCESS() == false)
        {
            power_manage();
        }
    }
}

Did you enable the power peripheral driver in sdk_config.h by setting #define POWER_ENABLED 1? You also need to include the source file in your project:

[SDK_ROOT]\components\drivers_nrf\power\nrf_drv_power.c

Yes, Thank you. That was the problem. Now I got another problem with Linking:

Error[Li005]: no definition for "nrf_drv_power_init" [referenced from C:\Users\admin\Desktop\Essentim\Nordic\Downloads\SDK\SamplenRF5_SDK_13.0.0_04a0bfd\examples\ble_peripheral\experimental_ble_app_blinky\pca10056\s140\iar\_build\main.o]

Could you please let me know how it could be solved?

Did you enable the TIMER module in sdk_config.h in the ble_blinky example by setting #define TIMER_ENABLED 1?
