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

Hello port-arm,

So far I have not found much information about this.

I see a commented out line in /etc/bluetooth/btattach.conf referencing
/dev/dplcom0, which I have uncommented. I also added a device "speaker"
along with its address for testing.

I did find a reference to needing the file
/libdata/firmware/bcm43xx/BCM43430A1.hcd which I found and have
installed.

The Gentoo wiki also suggested adding dtparam=krnbt=on to
/boot/config.txt but this had no effect.

This is NetBSD 10.0 arm64 image, a few boot message lines:
  simplebus0 at armfdt0: Raspberry Pi 3 Model B Rev 1.2
  plcom0 at simplebus1: ARM PL011 UART
  plcom0: txfifo disabled
  plcom0: interrupting on icu irq 57

When the rc.d/bluetooth runs, it shows:
  attaching Bluetooth controller to dplcom0
  btattach: bth5: Device not configured
  configuring Bluetooth controllers:.
  starting Bluetooth Link Key/PIN Code manager
  attaching Bluetooth HSET service from "speaker"
  btdevctl: sbt0: Device not configured
  attaching Bluetooth HSET service from "speaker"
  btdevctl: ubt0: Device not configured
  starting Bluetooth Service Discovery server


I find man pages for ubt and sbt, but nothing about bth.
also "btconfig" command returns nothing,
