NRF52840 advertise start and stop manually in logic

[manobala12]

Hi all,

I want to ON and OFF advertise manually

My code working steps 

1) (APP_ADV_DURATION 3000 ) after this seconds over  

2) It hits on_adv_evt() function in this function case :BLE_ADV_EVT_IDLE i use sd_ble_gap_adv_stop(m_advertising.adv_handle);

Till this point it's working properly

3) In uart_event_handle() function 

char buff[2];

char str_cmp[2]= "ON";

if ((data_array[index - 1] == '\n') || (data_array[index - 1] == '\r') || (index >= m_ble_nus_max_data_len))

{

      memmove(buff,data_array,2);

      if(buff == str_cmp)

      {

          int Val = memcmp(buff,str_cmp,2);

          if(Val == 0)

          {

               NRF_LOG_INFO("ON\n");

               ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);

               // ble_advertising_restart_without_whitelist(&m_advertising);

          }

      else

      {

             NRF_LOG_INFO("OFF\n");

         

       }

....

}

4) My Doubt is after 2nd Point hits 3rd Point will work or not

 

Otherwise suggest me how to advertise manually using uart_event_handle() function or any Idea

Hi,

If you want to due unlimited advertising duration, set APP_ADV_DURATION to 0 

And make sure you use General Discoverable Mode. i.e. in advertising_init() you have this:

init.advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

Then it will not time-out and stop.

And if you want to stop it manually,  try using sd_ble_gap_adv_stop()
