‘Reverse Engineering Furby Connect’s Bluetooth Protocol and Update Format’ #WarrantyVoided
Thanks to reader Mike for letting us know about GitHub user Jeija’s Bluefluff repo, which you can get a glimpse of it in action in the first video below.
With its Bluetooth Connection, Furby Connect is updated frequently with new surprises, like songs. When the antenna glows, this means Furby has something new to show you in the Furby Connect World app. Furby loves to share kid-friendly videos.
First things first: My Furby Connect “Dee-Koh” is safe and has not been harmed in the making of this. There is no need for physical access to the Furby in order to perform these kinds of hacks. This projects aims to reverse engineer / “hack” Furby Connect’s Bluetooth Low Energy protocol, graphics and audio format and eventually find a way to execute own code on Furby.
What I have achieved so far
Understand large parts of Furby’s BLE communication protocol
Open a secret debug menu in Furby’s LCD eyes
Control Furby’s actions, antenna color and LCD backlight
Control Furby’s emotions by setting his hungryness, tiredness, wellness etc. levels.
Get information on Furby’s sensor states including the antenna joystick, tickle / pet sensors and accelerometer
Update Furby with the official update “DLC” files from Hasbro or with my modified versions of those
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
