NAME

       ubertooth-dfu - Device firmware update for Ubertooth

SYNOPSIS

       To update firmware, run:

              ubertooth-dfu -d bluetooth_rxtx.dfu -r

DESCRIPTION

       ubertooth-dfu(1)  is  a  utility  for  updating firmware on Ubertooth. It can also download the currently
       running firmware from the device.

       Running the upload or  download  command  automatically  resets  the  device  into  the  firmware  update
       bootloader.  The  USB ID of the Ubertooth will change in the bootloader, and this may cause problems when
       attempting to update firmware from inside a VM.

       In the DFU bootloader, the TX, RX, and USR LEDs will turn on and off in sequence. If this does not occur,
       you  can  try  to  manually  force  the  device  to boot into the bootloader. Refer to [MANUALLY ENTERING
       BOOTLOADER][].

OPTIONS

       Major modes:

              • -d <firmware.dfu> : Download - write DFU file to device

              • -u <output.dfu> : Upload - read DFU file from device

              • -r : Reset device after performing operation

       Miscellaneous:

              • -s <file.bin> : Add DFU suffix to binary firmware file

              • -U <0-7> : Which Ubertooth device to use

MANUALLY ENTERING BOOTLOADER

       If the device does not enter the bootloader when running the upload or download commands, it is  possible
       to  force  the  device  to boot into that mode when it is inserted. To do so, you will need to jumper two
       pins on the expansion header.

       The expansion header is a 2x3 pin header between the two  largest  chips  on  the  board,  about  halfway
       between  the USB connector and antenna. It is labeled "EXPAND" on the back side of the board. Holding the
       board so USB is pointed up, on the front side of the board the expansion header looks like this:

                +-------+
              6 + O | O | 3
                +---+---+
              5 + O | O | 2
                +---+---+
              4 + O | X | 1
                +---+---+

       PIN #1, marked X, is square.

       With Ubertooth unplugged, use a piece of wire, paperclip, staple, etc to connect pins 1 and  2  together.
       When  it  it  plugged  in, the Ubertooth should enter bootloader mode (LEDs will be turning on and off in
       sequence).

       The bootloader will exit after 5 seconds of no activity and boot into the main firmware.
