  • Solos Smart Glasses were released in 2018 targeting cyclists and runners but were not a commercial success.
  • The glasses were reverse-engineered to understand their Bluetooth protocol for displaying images.
  • Bluetooth traffic was captured and analyzed to decode the image data transmission format, which uses Run-Length Encoding (RLE).
  • A Python script was developed to send custom images to the glasses, demonstrating the ability to display arbitrary content.
  • The glasses can still be used with their original app, making the modifications non-destructive.
  • Future enhancements could include utilizing the built-in microphone and speakers for additional functionality.
