Instead of 'Connection refused' messages, the Fedora client would now get 'Connection reset by peer'. There was nothing obvious in the logs on either machine but I can post them if necessary. I decided to try other versions of BlueZ to see if it made any difference. I built and installed the following from source on Ubuntu 15.10: v5.36: segfault on bluetoothd startup v5.34: same failure behavior as 5.35 above v5.33: same failure behavior as 5.35 above v5.32: same failure behavior as 5.35 above v5.31: same failure behavior as 5.35 above v5.30: works! I compared the v5.30 and v5.31 sources to see if anything stood out. I noticed this entry in the ChangeLog: > Fix issue with profile connections from remote devices. Sounds like it might be relevant to my situation. Is there any more information on this issue?
