.Nd firmware download utility for Realtek 87XX/88XX chip based Bluetooth
USB devices
.Sh SYNOPSIS
.Nm
.Fl d Ar device_name
.Fl f Ar firmware_path
.Nm
.Fl h
.Sh DESCRIPTION
The
.Nm
utility downloads the specified firmware file to the specified
.Xr ugen 4
device.
.Pp
This utility will
.Em only
work with Realtek 87XX/88XX chip based Bluetooth USB devices and some of
their successors.
The identification is currently based on USB vendor ID/product ID pair and
interface class.
For Realtek devices the vendor ID should be 0x0bda
.Pq Dv USB_VENDOR_REALTEK
and the 0-th interface class/subclass/protocol should be a Bluetooth RF
Wireless Controller.
Non-Realtek devices are identified based on USB vendor ID/product ID pair.
.Pp
Firmware files are available in the
.Pa comms/rtlbt-firmware
port.
.Pp
The
.Nm
utility will query the device to determine which firmware image and board
configuration to load in at runtime.
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl D
Enable verbose debugging.
.It Fl d Ar device_name
Specify
.Xr ugen 4
device name.
.It Fl I
Enable informational debugging.
.It Fl f Ar firmware_path
Specify the directory containing the firmware files to search and upload.
.It Fl h
Display usage message and exit.
.El
.Sh EXIT STATUS
.Ex -std
.Sh SEE ALSO
.Xr libusb 3 ,
.Xr ng_ubt 4 ,
.Xr ugen 4 ,
.Xr devd 8
.Sh AUTHORS
.Nm
is based on
.Xr ath3kfw 8
utility used as firmware downloader template and on Linux btrtl driver
source code.
It is written by
.An Vladimir Kondratyev Aq Mt wulf@FreeBSD.org
under sponsorship from Future Crew LLC.
.Sh BUGS
Most likely.
Please report if found.
