iOS12 - AccessoryNotReachable and Read/Write Errors

Hi,


Has anyone had issues reading Logs Characterictis in iOS12 or write to the Lock Control Ponit? We are having issues in our app accessing HomeKit DoorLock accessory.

Testing our app against iOS 10 works flawlessly, iOS 11 works reasonably reliably, then iOS 12 gives "Read/Write operation failed" and "Accessory is not reachable" errors frequently throughout use.


Failed to read logs: Error Domain=HMErrorDomain Code=4 "Accessory is not reachable." UserInfo={NSLocalizedDescription=Accessory is not reachable.}


Failed to write clear logs command: Error Domain=HMErrorDomain Code=74 "Read/Write operation failed." UserInfo={NSLocalizedDescription=Read/Write operation failed.}


Any help is appreciated.


Thanks
