Hi All,

After cross compiling my driver, I am getting an error while inserting the bt modules.

Unknown symbol hci_free_dev (err 0)
Unknown symbol hci_alloc_dev (err 0)

Unknown symbol hci_unregister_dev (err 0)
Unknown symbol hci_recv_frame (err 0)
Unknown symbol hci_register_dev (err 0)

Please help me how to solve this issue.

Thanks in advance.

Hi All,

I have resolved the above issue, by compiling bluetooth as a module (ie by compiling kernel by placing 'M'--> as a module ),

But now After inserting BT, I need to scan for the devices using the tools "hciconfig and hcitool", so please tell me how to get those tools on the board.

Thanks in advance.

Hello Mutyalarao Neelapala,

Those tools are included on Bluez as far as I know. I would recommend reviewing which Bluez version you have on your image or adding one if needed.
