Bluetooth MIDI connection fails in Catalina

Since I upgraded to Catalina, my IOS devices can't connect to my Mac when I try to use a Bluetooth MIDI connection. I get the error in the console:


"...Error encountered checking pairing status: Error Domain=CBATTErrorDomain Code=15 "Encryption is insufficient."


Instead, it works to connect two IOS devices to each other via Bluetooth MIDI.


Does anybody has an advice on how to further narrow down the error? It seems that the protocol has been changed?

I can start a Bluetooth Connection from an IOS 12.4.2 Device. Only my updated IOS 13.2.3 Devices have this issue. Very dissapointing. Since my update to IOS 13.2.3 the Bluetooth Midi function is useless!
Does anyone have any advice on what to do to solve this problem?
