Hi everybody, We are currently passing BlueZ 5.50 (LE Host Subsystem) qualification process. I would like to know if anyone has already passed test cases "L2CAP/LE/CFC/BV-13-C" and "L2CAP/LE/CFC/BV-15-C". Test case "L2CAP/LE/CFC/BV-13-C" seems to require authorization at GATT service level instead of GATT characteristic level. Does it have sense? As far as I have seen there is no way in BlueZ tools (bluetoothctl, gatttool) to add authorization requirement to services, is it? KR, César
