BT device open doesn't work in Android Lollipop 5.1.1

[vikaskolapudi]

Hi All

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,

Vikas.

Hi Vikas

lollipop uses different kernel so recommended to apply to vendor of this BT

for updated driver.  Also vendor can provide guidelines for integrating driver

to system.

Best regards
