RTLBTFW(8) System Manager's Manual RTLBTFW(8) NAME rtlbtfw -- load firmware for Realtek 87XX/88XX Bluetooth USB devices SYNOPSIS rtlbtfw -d device_name -f firmware_path rtlbtfw -h DESCRIPTION The rtlbtfw utility downloads the specified firmware file to the speci- fied 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 cur- rently 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. EXIT STATUS The rtlbtfw utility exits 0 on success, and >0 if an error occurs.
