Wanting to code a bluetooth driver. Starting point?

OK, SO...

I am running FreeBSD 12.1-RELEASE on a Lenovo x260

I got the mobile broadband module working after some help and encouragement from members of the forums.

In an effort to have everything working on the laptop I've come up to a problem...

Bluetooth on this device doesn't seem to be supported.

I get the following after running service bluetooth start
/etc/rc.d/bluetooth: ERROR: Unsupported device

Soo. I'm guessing Bluetooth for this laptop isn't yet supported. dmesg doesn't have a ubt0 anywhere and in /var/log/messages the only mention of bluetooth is: /etc/rc.d/bluetooth: ERROR: Unable to setup Bluetooth stack for device ubt0

Yes I have searched google. Yes I have followed the handbook. The conclusion I come up with is it is a 4.1 Bluetooth device and not currently supported.

So.. What to do?

I am an intermediately skilled C programmer, I know the difference between a process and a thread, know what pointers are and how to abuse them as well as structs and linked lists.

I figure I might as well become part of the community and try and contribute something.. Where do I start?

I have a copy of the following;

FreeBSD device drivers
FreeBSD Rootkits(kernel hacking)

as well as; The design and implementation of the FreeBSD Operating System, 2nd Ed.

So I'm good for reading material. I just need a starting point. I have the laptop datasheet.

I like the ideals of FreeBSD and the community around it..I guess I'm just trying to say 'Hello World'

cheers.

Look for the code of the Linux driver (if it exists). Understand it and convert it to FreeBSD.
