I'm trying to setup a bluetooth-box with freeBSD 13. uname -a:
loading ng_ubt.ko in /etc/loader.conf
results in a two or three times mode to be started.
but the third time it's quiet and that's always a good sign for a machine.
Scanning is ok, my a2dp-sink bluetooth box is recognized.
But now:
hccontrol -n ubt0hci read_connection_list
leads to:
No matter what kinda kernel or stack (ubt1) I use, this shit happens.
Is it a driver error, a compile failure or a system bug?
Bluetooth with freeBSD would be cool thing, I'd save a lot for the dentist.
And with this Ubitek Magic Box under linux it's an example of the fight against proprietarism (pE A2DP fix!).
You'd handle her with care or she's gonna kill you and your family with making @world and @buildkernel bringing me to foreground - such a lota responsibility for not getting anything at all - but a lotta revenge-tribal-stuff-emotion is keeping us going!
Interested in any related reply,
