As you know, it is either the phone or the nRF51 device that disconnects the link. If you run the nRF51 in debug mode you can set a breakpoint on sd_ble_gap_disconnect(..) and the event BLE_GAP_EVT_DISCONNECTED. If the code hits sd_ble_gap_disconnect(..), it is the nRF51 that is disconnecting, and if the code hits BLE_GAP_EVT_DISCONNECTED, it is the phone that is disconnecting.
