Manual Pages  — RTLBTFW

The rtlbtfw utility downloads the specified firmware file to the specified ugen(4) device.

This utility will 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 ( 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.

Firmware files are available in the comms/rtlbt-firmware port.

The rtlbtfw utility will query the device to determine which firmware image and board configuration to load in at runtime.

The options are as follows:

-D
	Enable verbose debugging.
-d device_name
	Specify ugen(4) device name.
-I
	Enable informational debugging.
-f firmware_path
	Specify the directory containing the firmware files to search and upload.
-h
	Display usage message and exit.
