NAME

bcmfw - firmware download utility for Broadcom BCM2033 chip

based Bluetooth USB devices

SYNOPSIS

bcmfw [-h] -f firmware_file_name -m mini-driver_file_name -n
device_name

DESCRIPTION

The bcmfw utility downloads the specified mini-driver and

firmware files
to the specified device.

This utility will only work with Broadcom BCM2033 chip based

Bluetooth
USB devices. The identification is currently based on USB

vendor
ID/product ID pair. The vendor ID should be 0x0a5c

(USB_VENDOR_BROADCOM)
and the product ID should be 0x2033.

Due to copyright issues I will no longer provide mini-driver

and firmware
files for the device. These files can be obtained from the

Linux BlueZ
bluez-firmware package.

Visit http://www.bluez.org/download.html for details.

I am using the following files from the bluez-firmware-1.0

package:

MD5 (BCM2033-MD.hex) =

5580317158d07fc4ace90af04f8e1c73
MD5 (BCM2033-FW.bin) =

b4e142b3272cfe5a84b32fda6b4b032f

The options are as follows:

-f firmware_file_name

Specify firmware file name for download.

-h Display usage message and exit.

-m mini-driver_file_name

Specify mini-driver file name for download.

-n device_name

Specify device name.

FILES
