Alexander Yurchenko just committed some stuff which introduces Bluetooth support in OpenBSD:

Log message:
First step in Bluetooth protocol stack support.

Full commit message is available at MARC.

NOTE: This is work in progress, more to be done, so you cannot use GPRS from your cellular phone to go online yet.

    Awesome! I had looked into doing this myself, but it was over my head. How fully featured are the plans and how compatible is it with software for the FreeBSD stack? The log message says L2CAP and RFCOMM are on the way, but will major effort be needed to import things like sdpd and bthid (or will they be ported/imported at all)? There was some recent discussion over in FreeBSD about a virtual keyboard driver for bthid to send keyboard events to and they even mentioned wscons as an alternative solution, so maybe we've got a jump on that end of things.

    Way to go! Need testers? I've got 3 BT adapters, 2 BT capable phones, a BT headset, a BT keyboard, and a BT mouse (that I never could get working well, even in Windows).

      Socket interface is fully compatible with FreeBSD, so all FreeBSD apps require minimal porting work.

    Wow, this is definitely COOOL!!!

    Alexander, You make my day!

    the following might also be interesting to some: http://anil.recoil.org/projects/blueproxy.html (and yes, it has a bsd license)...

    This is definately cool. Especially since I just got an laptop with bluetooth support. :-)

    I think I will run out and buy a bluetooth USB-adapter tomorrow. They aren't that expensive.

    Which USB->Bluetooth adapters might be supported?

    1. By Bruno Rohée (82.224.28.96) bruno@rohee.com on

      e.g. my Dlink DBT-120 is. Recognized as

      ubt0: Cambridge Silicon Radio Bluetooth, rev 1.10/4.43, addr 2

      There aren't many bluetooth chipsets out there. Most USB bluetooth adapters are built on the CSR chipset (several versions out now). I believe the FreeBSD driver supports most of them, so I imagine this one will as well. All 3 of my BT adapters are CSR based and all 3 are from different manufacturers (Sony, TDK, and Microsoft).

          From what I've read, the Linux and FreeBSD Bluetooth drivers support some PCMCIA Bluetooth devices, but that they aren't recommended. The reason is that the USB BT adapters actually have a defined standard interface they all are supposed to generally comply with, but the PCMCIA adapters don't have anything like that. The result is that specific drivers have to be written (or adapted to) each card individually.

      My cheapo generic usb bluetooth adapter with a silicon wave chipset is supported.

      dmesg[0] and usbdevs -v[1] here. Product url[2]

      Oh, this is on a macppc machine.
