After android 4.2. The bluetooth stack changed to new Bluedroid stack which is located in /external/bluetooth/bluedroid.

This is android hardware module implementation for android bluetooth stack. This stack will trying to load a vendor library

named libbt-vendor.so.You need to implement your bluetooth chip library.

Android source tree has an example to implement the library in /device/common/libbt. Specially this is broadcom based

BT chipset. It's easy to modify it to support your bluetooth chip. The important things about this library are how to access

your HCI port and how to control Bluetooth RF.

Good luck!

Hi Raymond Wang,

Plat form IMX6SL

bluedroid on adroid kitkat 4.4.3

I have 2 issues one while data transfer, the other while enabling via GUI.

1) After enabling bluetooth, while transferring file from third party mobile to IMX_6SL board, file is getting transferred(TX), but vice versa (RX) is not happening, it is giving the error message :

File not Received

File : sample.jpg

Reason : Storage issue

2) And presently I am inserting my driver via GUI, I am getting an error message while enabling bluetooth via GUI ie Operation not permitted while loading .ko (driver)Please suggest me what to do?? whether I need to install my driver at boot by adding in init.rc?? if I do it always on boot bt will be in ON State only?? OR Do i need to build my driver along with android source code???

Please suggest me how to proceed further???

Thanks and Regards,

Mutyala Rao.

FYI. All my source tree located at xhteam · GitHub

device-fsl/qpad_6dq at imx_jb · xhteam/device-fsl · GitHub

is my board definition directory. It's long time since my developing work almost finished.

And I can't remember when I insert .ko file (init.xxx.rc or in single program)

Hope this can help you.
