How can I find the long term key being currently used

[Beat Zenerino]

I'm using the s110_nrf51822_5.2.1_softdevice with the NRF51822. If I understand correctly, after pairing the NRF51822 with a phone, a long term key has been generated and stored in flash. Is there a function in the s110 I can use to get a pointer to the LTK or the LTK itself? Or maybe there is a way to intercept a gap or bond_manager event?

Thanks --Beat

Hi Beat Zenerino,

If the LTK have been distributed it will be available when you receive the BLE_GAP_EVT_AUTH_STATUS event. You can either process the event before or after it has been processed by the bond manager, or you can try to tap in to where the bond manager stores it.
