    Can we authenticate ble pairing on devices with no input and no output capabilities?



      I'm using BLE 4.2 in a project with GAP security level "Unauthenticated pairing with encryption" since I have no I/O capabilities currently available. I was wondering if there's any standard way to implement authentication for such devices? Is dedicating a GATT characteristic to exchange custom authentication keys, a good idea?


      Any suggestions are much appreciated.
