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 ?).
