Stop Advertising on nrf52832

[Mauro Silva]

Hi! What is the proper use of sd_ble_gap_adv_stop in SDK 15? I'm using nrf52832 in my application but can't seen to find a corret way to stop advertising.

Looking on ble_gap.h I've seen that this function requires a adv_handle as a parameter but what exactly is it expecting?

I think you can look around this document which shows how to use Advertising on BLE. Moreover, if you want to stop advertising, you can do like this.

- You have to generate the event with interval delay after sd_ble_gap_adv_start is called then try to call sd_ble_gap_adv_stop after calling sd_ble_gap_adv_start and waiting for time with timer.

I've found a workaround.

I was using sd_ble_gap_adv_stop(m_advertising.adv_handle)  inside a timer handler which had a return type of void while sd_ble_gap_adv_stop has a return type of uint32_t, so I just adjusted that and now it's stopping advertising and not showing the error.

Since app_timer_create was complaining about the uint32_t type I just called a function inside it to match the types.

//handler
void test_handler(void *p_context){

advertising_stop();

}
//advertising_stop
uint32_t advertising_stop(void)
{

uint32_t ret_error2;
ret_error2=sd_ble_gap_adv_stop(m_advertising.adv_handle);
APP_ERROR_CHECK(ret_error2);
NRF_LOG_INFO("ADV. Stopped");

}
