nrf51 DK crash after 5mins

[ypearson]

I'm running a BLE Free rtos example code with the UART service example code.

I noticed that after 3-5 minutues of advertising the BLE service it stop advertising...I'm guessing a crash. Any ideas why ? How would one debug this kind of issue. thanks,

Below is the ble thread, pretty much just stock code from the SDK.

    static void ble_stack_thread(void * arg)

{
    uint32_t err_code;
    bool erase_bonds;

    APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);

    ble_stack_init();
    gap_params_init();
    services_init();
    advertising_init();
    conn_params_init();

    err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);

    while (1)
    {
        /* Wait for event from SoftDevice */
        while(pdFALSE == xSemaphoreTake(m_ble_event_ready, portMAX_DELAY))
        {
            // Just wait again in the case when INCLUDE_vTaskSuspend is not enabled
        }

        // This function gets events from the SoftDevice and processes them by calling the function
        // registered by softdevice_ble_evt_handler_set during stack initialization.
        // In this code ble_evt_dispatch would be called for every event found.
        intern_softdevice_events_execute();
    }

}

static uint32_t ble_new_event_handler(void)
{
    BaseType_t yield_req = pdFALSE;
    // The returned value may be safely ignored, if error is returned it only means that
    // the semaphore is already given (raised).
    UNUSED_VARIABLE(xSemaphoreGiveFromISR(m_ble_event_ready, &yield_req));
    portYIELD_FROM_ISR(yield_req);
    return NRF_SUCCESS;
}

Most SDK examples stop advertising after some time. This is due to usage of a advertising manager module ble_advertising.h. Google suggests that you are using example code similar to this. Look for on_adv_evt function, specifically for BLE_ADV_EVT_IDLE event. Change sleep_mode_enter(); to advertising_start();. As for debugging use nrf_log.h and either UART or RTT.

That's likely it. Thanks

I'll test it and report back.
