Prohibit a certain Bluetooth address with the same UUID from connecting

[tony55723]

Hello Nordic Engineer,

I used SDK17.1.0

First chip is examples \ ble_central_and_peripheral \ experimental \ ble_app_multirole_lesc

static void scan_init(void)
{
    ret_code_t          err_code;
    ble_uuid_t          target_uuid = 
    {
        .uuid = BLE_UUID_HEART_RATE_SERVICE,
        .type = BLE_UUID_TYPE_BLE
    };

    err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_UUID_FILTER, &target_uuid);
}

Second chip is examples \ ble_peripheral \ ble_app_hrs

And Second chip BLE address is 11:22:33:44:55:66

static void scan_evt_handler(scan_evt_t const * p_scan_evt)
{
    ret_code_t err_code;

    switch(p_scan_evt->scan_evt_id)
    {
        case NRF_BLE_SCAN_EVT_CONNECTING_ERROR:
        {
            err_code = p_scan_evt->params.connecting_err.err_code;
            APP_ERROR_CHECK(err_code);
        } break;
		
		case NRF_BLE_SCAN_EVT_WHITELIST_ADV_REPORT:
        {
            // do something
        } break;

        default:
            break;
    }
}

If I want to ban the device with the address "11:22:33:44:55:66", should I do something in the "do something" in the code block?

Thanks

Hi tony55723,

Our apologies for the wait, it has been a holiday here.

The answer depends on what scanning mode you are using.

As you have set a filter, I assume you are scanning with a filter, and not with a Whitelist. If so, you need to handle NRF_BLE_SCAN_EVT_FILTER_MATCH. Though in this case, to avoid a device, it is simplest to just exclude it in the list of address to filter for.

If you are using scanning with whitelist, then the event generated will be NRF_BLE_SCAN_WHITELIST_ADV_REPORT.

For more information, please go over the Scanning Module documentation: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_ble_scan.html.
