key delay and nrf_delay_ms() function

[xiang san]

HI

   The SDK is "nRF5_SDK_for_Thread_and_Zigbee_v4.1.0" and I find a question that is: for all thread programs, add  nrf_ delay_ ms () function in while (true) will affect the operation delay of the key, what's the matter? 

  thanks!

You want a delay on a button in your application, is that correct? Please check out the button handler library, because a delay function in your main loop will just add a delay between what ever functions are on either side between the two.

Best regards,

Simon

Hi 

Yes,you are right,but my question is adding a delay to the main loop  why cause a delay of button event? you can have a try ,so you can know what I say.  and if I add code segment in main loop it will cause button maybe invalid.

thanks.

static void bsp_event_handler(bsp_event_t event)
{
    switch (event)
    {
        case BSP_EVENT_KEY_0:
            nrf_gpio_pin_clear(14);// new add
            //thread_coap_utils_unicast_light_request_send(THREAD_COAP_UTILS_LIGHT_CMD_TOGGLE);
            break;



while (true)
    {
        thread_process();
        app_sched_execute();
       
        nrf_delay_ms(1000);  //new add
       
        if (NRF_LOG_PROCESS() == false)
        {
            thread_sleep();
        }
    }
