Reverse Engineering Solos Smart Glasses: Displaying Arbitrary Images on a Retro Gadget

2025-09-04

A hacker successfully reverse-engineered the Solos smart glasses released in 2018 and managed to display arbitrary images on their screen. By analyzing Bluetooth packet captures, they discovered the communication protocol between the glasses and the smartphone app. Using a Python script, they RLE-encoded image data and sent it to the glasses, successfully displaying custom images. While some protocol details remain a mystery, this work demonstrates the customizability of the glasses and opens up possibilities for future development, such as displaying email subjects, weather forecasts, and more.
