Device not advertising when added DFU service into the applcation.

If you go to the Reference of the function nrf_drv_gpiote_init() in nrf_drv_gpiote.h you can find this:

/**
* @brief Function for initializing the GPIOTE module.
*
* @details Only static configuration is supported to prevent the shared
* resource being customized by the initiator.
*
* @retval NRF_SUCCESS If initialization was successful.
* @retval NRF_ERROR_INVALID_STATE If the driver was already initialized.
*/
ret_code_t nrf_drv_gpiote_init(void);

And error code 0x08 is equal to NRF_ERROR_INVALID_STATE

This meant you already initialize the gpiote driver some where else. Please check in your code.

Hi Hung,

I Debugged the code as you said.

// Initialze driver.
err_code = nrf_drv_gpiote_init();
APP_ERROR_CHECK(err_code);

I am getting error in the above function and the err_code it is throwing is 0x00000008.

Could you please help me in fixing this?

I'm not sure why it should restart, please make sure you change the optimization level to 0, add DEBUG into the preprocessor symbols.

If you can see the error return 0 , I don't think there would be any restart here. If you can step to APP_ERROR_CHECK, how would it restart ? Have you tried to step into nrf_drv_gpiote_in_init() ?

err_code = nrf_drv_gpiote_in_init(13, &in_config, button_duration_handler);
APP_ERROR_CHECK(err_code);

The above function restarting the system.But the returned err_code value is 0.

I am not able to figure out why it is restarting, could you please help me?

Again, please follow the debugging guide. You need to check for the error code AFTER you call a function. In your code, you have APP_ERROR_CHECK(err_code); at line 18 without any value assigned to it.

Hi Hung,

Thanks for the reply, I am able to solve the issue.

I have added

p_ble_enable_params->common_enable_params.vs_uuid_count = 2; in softdevice_handler.c then it is advertising.

Now I am facing another issue where in the same code I have added a gpio interrupt, but when configuring input pin for enabling interrupt it is restarting the system.

///**@brief Function for initializing the GPIOTE handler module.
// */

// Button event handler.
static void button_duration_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
   static uint32_t button_pushed_time;
		static uint32_t button_released_time;
		static uint32_t button_pressed_time;
	   uint32_t err_code;
	
    if (action == APP_BUTTON_PUSH)
    {
        
						     
					        //err_code = app_timer_start(m_led_a_timer_id, APP_TIMER_TICKS(200, APP_TIMER_PRESCALER), NULL);
			            printf("\r\n in the button handler");
                  APP_ERROR_CHECK(err_code);
								  app_timer_cnt_get(&button_pushed_time);
					        button_pushed_time=app_timer_sec(button_pushed_time);
			            while(!nrf_gpio_pin_read(13));
			             app_timer_cnt_get(&button_released_time);
			             button_released_time=app_timer_sec(button_released_time);
							   	app_timer_cnt_diff_compute(button_released_time, button_pushed_time, &button_pressed_time);  
					         if((button_pressed_time<3))
							   	{
							    	nrf_drv_gpiote_out_clear(19);
                    nrf_drv_gpiote_out_set(20);	
								  }
                  else if(button_pressed_time>=3)
							     {
		               nrf_drv_gpiote_out_set(19);
                   nrf_drv_gpiote_out_clear(20);	     
							     }
			             
								
									
                     
    }

 }




// Function for configuring GPIO.
static void gpio_config()
{
    ret_code_t err_code;

    // Initialze driver.
    err_code = nrf_drv_gpiote_init();
    APP_ERROR_CHECK(err_code);
	nrf_gpio_cfg_output(19);
    nrf_gpio_cfg_output(20);
    // Set output pins (this will turn off the LED's).
    nrf_drv_gpiote_out_set(19);
    nrf_drv_gpiote_out_set(20);

    // Make a configuration for input pints. This is suitable for both pins in this example.
    nrf_gpio_cfg_input(13, NRF_GPIO_PIN_PULLUP);
    nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_HITOLO(true);
    in_config.pull = NRF_GPIO_PIN_PULLUP;

    // Configure input pins for buttons, with separate event handlers for each button.
    err_code = nrf_drv_gpiote_in_init(13, &in_config, button_duration_handler);
    APP_ERROR_CHECK(err_code);
    // Enable input pins for buttons.
    nrf_drv_gpiote_in_event_enable(13, true);

}

Above are the functions for button_event_handler and for configuring the gpio.

could you please help me in solving this issue?

Hi Kishor,

When your code doesn't work as expected, for example not advertising, you can debug.

To debug, you can follow this guide. We want to know which function at which file causing assertion and with which error code.
