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

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?

[Vincent]

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?

Hi The whole Information like below: SDK: nRF5_SDK_12.1.0_0d23e2a Example Code: ble_app_hrs_rscs_relay MCU: nRF52832 on PCA10040 Board SD: 132 The Modify parts:

static void adv_scan_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 scanning for peripherals and initiate connection to devices which
    // advertise Heart Rate or Running speed and cadence UUIDs.
    //scan_start();

    // Turn on the LED to signal scanning.
    LEDS_ON(CENTRAL_SCANNING_LED);

    // Start advertising.
    err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);
}

}

#define NRF_CLOCK_LFCLKSRC      {.source        = NRF_CLOCK_LF_SRC_RC,            \
                             .rc_ctiv       = 16,                                \
                             .rc_temp_ctiv  = 0,                                \
                             .xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}

That are parts of example code I modify. and I set the

#define APP_ADV_TIMEOUT_IN_SECONDS       20

and the nRF52 stop advertising after 20 second but the on_adv_evt has no BLE_ADV_EVT_IDLE flag trigger.

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"); LEDS_ON(PERIPHERAL_ADVERTISING_LED); break;//BLE_ADV_EVT_FAST

    case BLE_ADV_EVT_IDLE:
    {
				  NRF_LOG_INFO("BLE_ADV_EVT_IDLE\r\n");
        ret_code_t err_code;
        err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
        APP_ERROR_CHECK(err_code);
    } break;//BLE_ADV_EVT_IDLE

    default:
        // No implementation needed.
        break;
}

}

Okay, I see. Do you have added (registered) on_adv_evt (..) as the event handler in ble_advertising_init(..)?
