Hi Sowmya.

I don't use /dev/dsp to get audio samples. I use ALSA project library and i=
t
works (I suggest you should look for code samples about it, specially those
regarding to headsets).

CVSD is the default on-the-air coding for SCO packets but you can change it
by means of "hciconfig".

For SCO transmission, just open a socket as in scotest.c (bluez-utils/test)
and use write and read on it.

There is no documentation about BlueZ and, if you want to use it, you must
read and undestand the code.

Bye!
