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

BCM2033-MD.hex: Mini-driver image.
BCM2033-FW.bin: Firmware image.
/dev/ubtbcmfwN.EE: Endpoint EE of device N.

EXIT STATUS

The bcmfw utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

To download the firmware into the /dev/ubtbcmfw0 device:

bcmfw -n ubtbcmfw0 -m BCM2033-MD.hex
  -f BCM2033-FW.bin
