Re: [Bluez-users] How to enable eSCO in linux 2.6.18?

["dong yan" <semiydsemiyd@gmail.com>]

Hi Sumeet VERMA:

    I'm just writing this to tell you that your esco patch for 2.6.18
works well.I modified some settings within the sff file , use "hstest"
to establish an esco connection and then send the audio data directly
into pcm interface connected to stlc2500. Now i can play/record music
on esco.
    Thanks for the patch!

Best Regards

semiyd
