In the last some days i read a lot and found the following :
1. download the widcomm stack from axim site : LINK
2. install it + do a soft reset
3. get a registry edittor (Resco, CECMD etc.)
4. change these values :
BaudRate=115200 (Won't start at higher rate.)
Port=1 (This is the most important thing!)
-at the today screen you will find a BT icon, click on it and have fun
-BT FTP, tested with : SE K750i, hx4700.
-ActiveSync : NOT WORKING
-unable to control from comm manager
-blue led not flashing, easy to forget
-a2dp not tested
-tested on aku3.2 and aku2.3 roms, others maybe ok.
-other devices can't download bt services list, but the services works well.
-maybe unable to remove, not tested yet
-turns off, when you trun off your device, that maybe a problem with BT headset.
DO IT ON YOUR OWN RISK
