Hi TI member,

I face some BT porting issue for on it and following the link

http://processors.wiki.ti.com/index.php/TI-Android-JB-4.2.2-DevKit-4.1.1_PortingGuide#Bluetooth

it will show some failed logs as like below, I may some mistake for it ,

is there any information I can follow ? I've found Android 4.2 can not support "hciconfig" control,

how should implement ? any location of information I could reference ?
