If you are using the advertisement module you simple stop and start advertisement, and then on BLE_ADV_EVT_WHITELIST_REQUEST event you call ble_advertising_whitelist_reply() with the desired peer.

If you are not using the advertisement module it should be possible to call sd_ble_gap_whitelist_set() directly yes.

Thank you, But i how to enable BLE_GAP_EVT_SCAN_REQ_REPORT event in event handler? because i followed many blogs but i could not achieve it.

You can use the BLE_GAP_EVT_SCAN_REQ_REPORT event, because this event include RSSI value and GAP address of the scanner, and based on this you can the for instance add the scanner to the whitelist if you want to allow connection.

For this to work you should set BLE_GAP_ADV_FP_FILTER_CONNREQ when advertisement, since it will allow all peers to send scan request (cause BLE_GAP_EVT_SCAN_REQ_REPORT event), but only those in the whitelist can connect.

how to add Known MAC ID to the whitelist without bonding ?

It is typically used to whitelist devices that have been previously bonded yes. But you may just add devices (if you know the gap address of the peer) as you see fit on BLE_ADV_EVT_WHITELIST_REQUEST.

Hi,

Peer id is:
http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.2.0%2Fgroup__peer__manager.html&anchor=ga0aa174d9642816af3ba36db985465f46

Usage:
http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/lib_pm_usage.html?cp=4_0_0_3_2_7_2

If you set: init.config.ble_adv_whitelist_enabled = true;
before calling: err_code = ble_advertising_init(&m_advertising, &init);

Then the advertisement will ask for the whitelist by BLE_ADV_EVT_WHITELIST_REQUEST in on_adv_evt(). Look at the hid keyboard example how the application request the peer manager to create the whitelist from already bonded peers.

Best regards,
Kenneth
