How to handle GAP Security related events?

[RJ Fang]

Hi all,

I was looking at all ble events and found a few GAP events related to security:

BLE_GAP_EVT_SEC_PARAMS_REQUEST

BLE_GAP_EVT_SEC_INFO_REQUEST

BLE_GAP_EVT_PASSKEY_DISPLAY

BLE_GAP_EVT_KEY_PRESSED

BLE_GAP_EVT_AUTH_KEY_REQUEST

BLE_GAP_EVT_AUTH_STATUS

BLE_GAP_EVT_CONN_SEC_UPDATE

and I found they are handled in the security_dispatcher.c, is there anything I need to do to handle these events? Or I can just let the softdevice handle them.

Best regards,

RJ

Hi,

If you want to support bonding the recommended approach is to start with an BLE example project that support bonding already. If the BLE example include the Peer Manager library, then the example support bonding, ref documentation: 
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_peer_manager.html and 
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_pm_usage.html 

If you want to understand more about the BLE events and softdevice api the Peer Manager is calling you can find BLE message sequence charts useful:
