An independent developer has published a detailed technical breakdown of how he reverse-engineered the Solos Smart Glasses, a wearable device originally released in 2018 and now largely abandoned.
With no official SDK or documentation available, the project began with a $30 eBay purchase and turned into a full protocol analysis. The result: custom image rendering on the device’s heads-up display using Python and Bluetooth packet injection.

Key Technical Highlights
- Captured Bluetooth packets between the official app and device
- Identified proprietary packet prefix (
1d60) - Decoded image data using Run-Length Encoding (RLE)
- Reconstructed RGB 5:6:5 frames for 428×240 pixel display
- Sent custom visuals to the HUD using Python tooling
Why It Matters
This project demonstrates how legacy hardware can be repurposed through reverse engineering, even without vendor support. It also showcases practical techniques for protocol analysis, image encoding, and embedded display control.
For developers interested in Bluetooth hacking, wearable tech, or hardware preservation, it’s a compelling case study in low-level device interfacing.
If you’re working on similar projects or curious about how to revive forgotten devices, this is worth a read.
