Device not advertising when added DFU service into the applcation.

I am trying to add DFU service to my custom application, I have taken ble_app_hrs_s132 with DFU as a reference and added all the required files and made required changes in my application but when I flashed the code into the board, the board is not advertising.

I am using nRF52832 board, sdk v11.

The below one is the code.

Could anyone help me in solving this.

  • 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.

        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?

  • 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. 

  • 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?

  • 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() ? 

  • 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?
