Re: [Bluez-devel] gumstix+infineon can't scan/connect

[Brad Midgley <bmidgley@xmission.com>]

hmmm

this was all done by ssh'ing into the gumstix over a PAN connection. I 
guess this radio is like those in cellphones... it can only handle one 
connection at a time (argh).

the good news is a2play is able to run with a load of 1.6. this is with 
too short a usleep delay and soft double-precision fp. so things can 
only improve with real timing and maybe using single-precision soft fp 
and eventually integer-only ops.

things are still pretty flakey with infineon bluetooth. sometimes 
something like avdtp negotiation won't work but after resetting the 
stick it works fine.
