The perfect blend!! Reversing a Bluetooth protocol for better smoothies! - Ryan Mast at !!Con 2024

The Perfect Blend!! Reverse engineering a bluetooth protocol for better smoothies! Have you ever gone to make a smoothie, only to have the blades spin fruitlessly while the fruit sticks just out of reach on the walls of the cup? I’ve wrestled with a “smart” blender over this and other issues on many occasions, often resorting to tossing the single serving cup to dislodge stubborn pieces of fruit. In this talk, I’ll share how I learned to reverse engineer BLE devices in order to control the exact settings used by the blender, including initial failures and how I overcame them. And in the end, we’ll create a custom blending profile for the perfect blend! Ryan is a software engineer working on open source projects to make the electric grid more reliable. His interests include software security, niche video games, and reverse engineering audio/video hardware used in live productions.
