Bumblebee is a specific firmware designed for Texas Instruments CC2531 RF System-on-Chip that allows IEEE 802.15.4 (ZigBee) packets sniffing and packet injection for RiverSecLoop's Killerbee framework.

This firmware is based on Contiki (not Contiki-ng), and uses a USB CDC serial interface to communicate.

This firmware is designed to run on a $10 TI CC2531 USB device shown below:

The last compiled version of this firmware is available in the Releases section. This is the recommended way to get a fully working and tested version of Bumblebee.

First, you need to install the correct version of SDCC by following these instructions.

Then, clone this repository including the submodules:

$ git clone --recursive https://github.com/virtualabs/cc2531-killerbee-fw.git

And build the firmware:

$ cd cc2531-killerbee-fw
$ make

The firmware file will be generated and named cc2531-bumblebee.hex.

If you own a CC Debugger, just follow this tutorial and use Bumblebee firmware (.hex release) instead of ZNP.

If you are looking for alternatives, follow this other tutorial with Bumblebee firmware. You may need an Arduino board, an ESP8266 or a Raspberry Pi to be able to flash your CC2531 USB dongle.
