sd_app_evt_wait not wake from sleep mode

[nagaraj]

Hi,

   We are using nrf51822 QFAAH00 with SDK 110 v10.0.0 with softdevice 8.0.0 in our project, In Application we are using gpio,timer,uart interrupt handler, In main function added sd_app_evt_wait function in while to wake up on event or interrupt, after sometime Application stuck in sleep mode and executing only the gpio,ble_event_handler,timer interrupt handler and bluetooth connection with central working fine. is it sd_app_evt_wait function failing to wake up from sleep mode?

Thanks,

nagaraj

I am not sure what this means? Do you mean that after calling sd_app_evt_wait() in a while loop, if still gpio interrupt handler is working, then the chip is waking up from sleep and going back to sleep again.

hi...susheel

kindly help me ... i want to put my device is sleep mode 

i have called the sd_app_evt_wait() in main loop but it doesn't work

/**@brief Application main function.
 */
int main(void)

{
    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();
    
    twi_init();
    LM75B_set_mode();
    
      while (true)
    {
        nrf_delay_ms(5000);

        do
        {
            __WFE();
        }while (m_xfer_done == false);
      
     
       
        // read_sensor_data();
       //  power_manage();
         threshold_value();
      sd_app_evt_wait();
        NRF_LOG_FLUSH();
    }
    }
