BlueZ 5.64
DBus Monitor output
If I understand this log correctly, member=Pair gets an error reply of "error_name=org.bluez.Error.AlreadyExists", "Already Paired", even though the "Paired"? property is false, and never gets a "PropertiesChanged" member message.
This problem went away after rebooting, but happened over and over again, every time I ran my program.
If I understand this log correctly, member=Pair gets an error reply of "error_name=org.bluez.Error.AlreadyExists", "Already Paired", even though the "Paired" property is false, and never gets a "PropertiesChanged" member message.
Is this a problem in my program, or a bug? Because I was getting this issue, I put a loop in my program to Pair multiple times, waiting a second between attempts, and always check the get results of the Paired property which was always false. Each time I attempted the pair, I got the error that it was already paired.
