Bluetooth and buffer overflow issues

Bluetooth and buffer overflow issues

Fedora 30 all latest updates applied (could try and update to 31 to see
if it makes any difference but I doubt it)

Tried re-scanning and re-pairing with no change.

Heinrichs Weikamp OSTC3+ firmware 3.05 and just updated to 3.07 with no
difference

Both Shearwater Petrel 2 and Nerd 2 Bluetooth both download ok with my
self built latest master.



latest Appimage:Import > Import from dive computerNot available
The local Bluetooth adaptor cannot be accessed.
from terminal ./Subsurface.AppImage -vvCannot find a running Bluez.
Please check the Bluez installation.

4.9.3 offical appimage could also not find the bluetooth radio but I
thought that had been fixed in more recent builds so is this a
regression?Maybe I am mistaken and it has only been my own builds that
work?
