Got it, thank you! I'll try to implement restart_without_whitelist() then, that seems like exactly what I need.

Hi,

There seems to be a bug in the HID mouse example. The handling of the BLE_ADV_EVT_SLOW_WHITELIST event is like this:

        case BLE_ADV_EVT_SLOW_WHITELIST:
            NRF_LOG_INFO("Slow advertising with whitelist.");
            err_code = bsp_indication_set(BSP_INDICATE_ADVERTISING_WHITELIST);
            APP_ERROR_CHECK(err_code);
            err_code = ble_advertising_restart_without_whitelist(&m_advertising);
            APP_ERROR_CHECK(err_code);
            break;

which is not correct. It should have been the same as the keyboard example (where it does not start advertising without whitelist here):

        case BLE_ADV_EVT_SLOW_WHITELIST:
            NRF_LOG_INFO("Slow advertising with whitelist.");
            err_code = bsp_indication_set(BSP_INDICATE_ADVERTISING_WHITELIST);
            APP_ERROR_CHECK(err_code);
            break;

In both cases whitelisting can be explicitly turned off by a button press, where ble_advertising_restart_without_whitelist() is called on the BSP_EVENT_WHITELIST_OFF event. This is the correct approach for a HID device, which you only want to advertise without whitelisting when you are specifically trying to connect it to a new central.
