Ok well it didn't work, attached is the gsmbluetooth.state file I am trying to use if anyone is
interested and wants to try it. I set this as best I could from comparing the differences between
the gsmhandset.state and gsmheadset.state for the gta01 and transcribing to gta02 as best as
possible given the undocumented differences between the two.
After calling the cell phone I did an alsactl -f gsmbluetooth.state restore.
In the process I just discovered the Qtopia (this is for you Lorn ;) did not load
/usr/share/openmoko/scenarios/gsmhandset.state when the call was answered, I had to do it manually,
I'm pretty sure this is a regression.
Also the options available in the menu when in a call to set speakerphone handset or bluetooth do
not seem to do anything.
I'm pretty much out of ideas on how to get a working gsmbluetooth.state file for gta02, so someone
else chime in if you think of anything.
I see this as a show stopper for the unit being usable as a phone so if anyone at OM cares I'd get
on it ASAP.
