Re: [Bluez-devel] handsfree profile

[robert <rbscott@cadvium.net>]

Hello Marcel,

So I was planning to implement the profile inside of java, which is  
why I am working on the Avetana BT stack, but I don't beleive that I  
can handle any of the SCO communication from java.  Essentially I am  
planning write the command processor for handling the AT commands in  
Java (easier to maintain and debug), and then just create a small  
daemon that handles routing traffic between the SCO channel and the  
Alsa devices.  Perhaps communicate between the two using D-Bus?

Is that possible?

Cheers,
Robert
