SDk12 ble_app_hrs_rscs_relay has no BLE_ADV_EVT_IDLE in on_adv_evt

[Vincent]

Hi I use ble_app_hrs_rscs_relay example with sdk12 and when the APP_ADV_TIMEOUT_IN_SECONDS is reach the nrf52 stop advertising but the on_adv_evt has no BLE_ADV_EVT_IDLE flag coming.

I do ble_advertising_start only now. Do I need call sd_ble_gap_scan_start on the same time with this example.

Thanks

Yes, in BLE_ADV_EVT_IDLE, calling ble_advertising_start() is all you need to do to start advertising.

Note: If you don't want advertising to time out, the advertising timeout can be set to '0'.

Hi Kristin, Sorry I means I did calling

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

and it did timeout because it has no any ble advertising but the on_adv_evt has no BLE_ADV_EVT_IDLE occur.

of course I just need keep ble advertising until the Phone scan and connect. I will set the timeout to 0. but why the on_adv_evt has no BLE_ADV_EVT_IDLE occur.

Thank you.

Did you add BLE_ADV_EVT_IDLE to on_adv_evt(..), but BLE_ADV_EVT_IDLE never occurs?

static void adv_start(void) { ret_code_t err_code; uint32_t count;

//check if there are no flash operations in progress
err_code = fs_queued_op_count_get(&count);
APP_ERROR_CHECK(err_code);

if (count == 0)
{
    // Start advertising.
    err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);
}
	else
	{
		  NRF_LOG_INFO("flash operations in progress\r\n");
	}

}

static void on_adv_evt(ble_adv_evt_t ble_adv_evt)

{ switch (ble_adv_evt) { case BLE_ADV_EVT_FAST: NRF_LOG_INFO("Fast Advertising\r\n"); break;//BLE_ADV_EVT_FAST

    case BLE_ADV_EVT_IDLE:
				  NRF_LOG_INFO("Advertising Idle\r\n");
        //adv_start();
			break;//BLE_ADV_EVT_IDLE

    default:
        // No implementation needed.
        break;
}

}

I only add the printf and I was thought when the on_adv_evt got the BLE_ADV_EVT_IDLE then I scan again. The timeout time I set it is 30 second and it did stop advertising but I dont see the printf and mcu did not advertising again.

Thanks

Which version of the SDK do you use? When I test ble_app_gls from SDK 12.1.0 and enables fast advertising then timeout, it works ( the application hits BLE_ADV_EVT_IDLE).

How do you configure fast advertising?
