I am working on my company's BT Device and I would like to integrate it to Android Lollipop, my BT Device driver creates an entry /dev/bt_dev , I have also created libbt-vendor folder in the path /myandroid/hardware/imx/, when I enable BT from GUI control reaches the function userial_vendor_open but it fails in the open system call to /dev/bt_dev , my BT device is up and I can see device listed in /proc/devices. Any idea why open system call is failing. Same code works fine in Kiktat 4.4.3 but it is not working for lollipop.When I checked device driver end the android system doesn't seem to call this /dev/bt_dev open function.
Please help me to move forward.
Thanks & Regards,
