my platform is arm based.

my A2DP can work over bluetooth-audio-service, you know the A2DP is mapped to ACL. now I want to test SCO link to apply in headset, so how to do this?

I get some information through http://wiki.bluez.org/wiki/HOWTO/AudioDevices, but it needs python/python-dbus support, is there any method that go without python?
