Hi all,
I 'm working on the feasability of a Talkie-Walkie Application
with two dongles.
Does somebody knows some books or other documentation which
can give me information on how to make an audio application with bluez ?
In your opinion, what is (are) the main(s) problem(s) to realize such application ?
As I have read on the mailing list, the best way to work with SCO links under linux
is to use CSR Chipset. Does anyone know why these chipset is so suited
to work with linux and so bluez ?
thanks very much
Michel

It sounds like you have the luxury of not worrying too much about
latency. Audio is one-way for a walkie-talkie function. Also, you're
writing the code on both ends so you don't have to use any specific
protocol. Choose accordingly.
You could model something after the sco test in bluez or you could model
it after the a2play/a2recv in the btsco project.
sco advantages:
2-way audio
low-latency
low cpu use
a2dp advantages:
higher quality audio, even stereo
one-way audio
The SCO transport driver is only completely working for CSR chips.
