USB support in Bluedroid stack [Android 4.4.3 for imx6-Sololite]

Silwerstar — Wed, 24 Jun 2015 06:09:28 GMT

Hi,

Is support for USB available for Android 4.4.3 or higher android versions for imx6 platforms? I would like to connect my BT-USB device to the imx6 platform but I read somewhere that there isn't any support for USB in Bluedroid. What changes do I need to do in Android to support USB? Will it be available in the upcoming Android releases?

I was of the opinion that Bluedroid is a user-space stack so it may not have anything to do with the device interface. But looks like there is some dependency. Can someone help me with this question?

Thanks!

Hi all,

I am glad to inform you that the above issue which I have posted earlier got resolved, but I have another 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.
