Hi,

I have been using bluez 4.58 with 2.6.30 on ARM platform , I am newbie
and found problem with Headset & Dongle version mismatch.

I can use v2.0 Dongle with v2.0 Headset & v2.1 Dongle with v2.1
Headset.( result is good I can hear voice on HS)

But if I use v2.0 Dongle with v2.1 HS & v2.1 Dongle with v2.0 HS
result is unpredictable some time noise or No voice).

I am doing anything wrong with SCO implementation? OR Bluetooth have
limitation with version mismatch. OR I must use same version Dongle &
HS(why ?).

Thanks in Advance
