Watch Dog timer with Template/ble_app_uart example

Hello,

You need remove the nrf_soc.c and nrf_nvic.c file from the project. These files are only meant to be used in projects which don't include the Softdevice.

Hello Vidar,

Thanks for your reply

Now WDT is running properly...!!

i am trying to add WDT to ble_app_uart  example here is my main function code

int main(void)
{
        //==================================================================================
    
    uint32_t err_code = NRF_SUCCESS;

    //BSP configuration for button support: button pushing will feed the dog.
    err_code = nrf_drv_clock_init();
    APP_ERROR_CHECK(err_code);
    nrf_drv_clock_lfclk_request(NULL);

    err_code = app_timer_init();
    APP_ERROR_CHECK(err_code);

    err_code = bsp_init(BSP_INIT_BUTTONS, bsp_event_callback);
    APP_ERROR_CHECK(err_code);

    //Configure all LEDs on board.
    bsp_board_init(BSP_INIT_LEDS);

    //Configure WDT.
    nrf_drv_wdt_config_t config = NRF_DRV_WDT_DEAFULT_CONFIG;
    err_code = nrf_drv_wdt_init(&config, wdt_event_handler);
    APP_ERROR_CHECK(err_code);
    err_code = nrf_drv_wdt_channel_alloc(&m_channel_id);
    APP_ERROR_CHECK(err_code);
    nrf_drv_wdt_enable();

    //Indicate program start on LEDs.
    for (uint32_t i = 0; i < LEDS_NUMBER; i++)
    {   
        nrf_delay_ms(200);
        bsp_board_led_on(i);
    }
     err_code = bsp_buttons_enable();
     APP_ERROR_CHECK(err_code);
    
    nrf_drv_wdt_enable();
    
    //==================================================================================

    bool erase_bonds;

    // Initialize.
    uart_init();
    log_init();
    timers_init();
    buttons_leds_init(&erase_bonds);
    power_management_init();
    ble_stack_init();
    gap_params_init();
    gatt_init();
    services_init();
    advertising_init();
    conn_params_init();

    // Start execution.
    printf("\r\nUART started.\r\n");
    NRF_LOG_INFO("Debug logging for UART over RTT started.");
    advertising_start();

    // Enter main loop.
    for (;;)
    {
        //idle_state_handle();
    }
}

now i am facing the issue that, the device (nRF52832 DK) is not advertising (Nordic_UART)   so plz let me know the proper position to add the WDT code in main function.

the WDT delay i have changed from 2sec to 10sec.

So my requirement is i want to reset device for every 10sec.....

(now reset is happening but not advertising)

Hello,

I have already offered to debug your project. Just zip the project folder and upload it here if you can.

Hello,

thank you in advance

pca10040-->s132-->ses

Hello Vidar,

Plz let me know if u want any thing else

Hello,

Here's an updated version of your project:

I re-enabled logging over RTT. You can view the logs in the Debug terminal if you start a debug session in SES.

Hello Vidar,

Thank you so much... its working i assigned 15 pin for led but its 18..so i thought its not running...sorry...

now if i  use sd_power_system_off(); will WDT works after turn off device..??

turn off means just running sd_power_system_off(); 

my requirement is i want to turn off the device after my operation. and i should turn on using WDT. so how can we do  that

instead of   sd_power_system_off();  what can we use to save the power of the device

Hi..., '

can any body suggest the solution..??

It depends what you are trying to do. There are 2 main power modes on the chip: System OFF mode and System ON mode. The latter is more common and is entered by calling idle_state_handle() from the main loop.
