Hi Johnny,

You can check the sniffer trace to see what happened over the air.

If you don't want to use the sniffer, you can check the BLE_GAP_EVT_AUTH_STATUS event and check which security level you end up. If it's LESC and MITM, you will have security mode 1 and level 4. Check p_ble_evt->evt.gap_evt.params.auth_status.sm1_levels.lv4 if it's =1 .

If it's Just work you used, you will end up with security mode 1 and level 2 which is the same level as Legacy Pairing Just Work.

I believe the iOS nRFConnect app will show you if the device is bonded in the app. It say "Not bonded" or "Bonded"
