Bluetooth stack

A Bluetooth stack is software that is an implementation of the Bluetooth protocol stack.

Bluetooth stacks can be roughly divided into two distinct categories:

The FreeBSD bluetooth stack is implemented using the Netgraph framework. A broad variety of Bluetooth USB dongles are supported by the ng_ubt driver.

The implementation was committed in 2002, and first released with FreeBSD 5.0.

NetBSD has its own Bluetooth implementation, committed in 2006, and first released with NetBSD § 4.0.

OpenBSD has had the implementation from NetBSD for some time, but it was removed in 2014 due lack of maintainership and code rot.

DragonFly BSD has had NetBSD's Bluetooth implementation since 1.11 (2008), first released with DragonFly BSD § 1.12.

A netgraph-based implementation from FreeBSD has also been available in the tree since 2008, dating to an import of Netgraph from the FreeBSD 7 timeframe into DragonFly, but was possibly disabled until 2014-11-15, and may still require more work.
