Re: Is there a document for setting up Bluetooth on a Raspberry Pi 3B?

Besides GENERIC64 lacking the driver (which can be easily fixed), there
are other issues. The dtb (or something else) needs to configure the
GPIO pins correctly, you need to decide between console and BT interface,
you need the correct firmware files for the RPI model and BT chip, and
there is no safe method yet to recover the interface when it ran into
a problem.

If it works, it looks like:

arnold# uname -srp
NetBSD 10.99.10 aarch64
arnold# sysctl hw.model
hw.model = raspberrypi,4-model-b
arnold# btconfig

The "name" is confusing, the substring "Raspberry Pi 3" does not
refer to a Raspberry Pi Model 3.

N.B. the "Broadcom Bluetooth Device" above is a ubt(4) device in
a Thinkpad T420.
