How To Update Firmware
First, grab the latest Ubertooth release.
Then, extract the archive and change into directory
You may then run the
ubertooth-dfu command like so:
$ ubertooth-dfu -d bluetooth_rxtx.dfu -r Checking firmware signature No DFU devices found - attempting to find Ubertooth devices 1) Found 'Ubertooth One' with address 0x1d50 0x6002 Select a device to flash (default:1, exit:0):
Press enter, and the device will automatically enter DFU mode and flash the firmware. When done, you can return it into regular operation mode by unplugging and replugging it, or running
If you run into an error such as "libUSB Error: Command Error: (-1)" or the Ubertooth's 4 LEDs next to each other perform a distinctive chasing pattern, run:
make clean all && make && ubertooth-dfu -r -d bluetooth_rxtx.dfu
What Version Am I Running?
In non-DFU mode, you can obtain firmware information with
ubertooth-util -v. The latest release (2014-02-R1) will appear like this:
$ ubertooth-util -v Firmware revision: 2014-02-R1 $ ubertooth-util -V ubertooth 2014-02-R1 (dominicgs@mercury) Wed Jan 29 23:10:46 GMT 2014
You'll need a toolchain that supports ARM Cortex-M3. The Makefiles in the firmware directory are designed for GCC and a Linux-based toolchain, specifically
arm-none-eabi-gcc and libnewlib-arm-none-eabi. If you are running a Debian based distribution, you can run:
apt-get install gcc-arm-none-eabi libnewlib-arm-none-eabi
Otherwise it can be downloaded from https://launchpad.net/gcc-arm-embedded, just unpack the archive and add the bin directory to your PATH.
To build the firmware, start from the directory where you cloned or unpacked the source and run the following:
cd firmware/bluetooth_rxtx/ make
This will produce a file named
bluetooth_rxtx.dfu which can be written to the Ubertooth using
ubertooth-dfu -d bluetooth_rxtx.dfu -r
Although firmware source and binary images can be found in the release downloads, you will probably want fresh code from git if you are planning to modify the firmware.
