I have been reverse engineering the Even Realities G2 smart glasses BLE protocol. If you are interersted in joining this effort, please do!
The G2 glasses use a custom protocol created by EvenRealities. This BLE (bluetooth) protocol is used to transmit data in packets to and from the glasses. Currently, the G2 glasses are restricted to the functionality offered in the Even app - reverse engineering the BLE protocol removes this restriction.
| Feature | Status | Notes |
|---|---|---|
| BLE Connection | Working | Standard BLE, no special pairing |
| Authentication | Working | 7-packet handshake sequence |
| Teleprompter | Working | Custom text display confirmed |
| Calendar Widget | Working | Display events on glasses |
| Notifications | Partial | Metadata only (app + count) |
| Even AI | Research | Protocol identified |
| Navigation | Research | High display traffic observed |

# Display custom text on glasses
python teleprompter.py "Hello from Python!"
# Multi-line text
python teleprompter.py "Line one
Line two
Line three"- BLE Services & UUIDs - Complete characteristic mapping
- Packet Structure - Transport layer format
- Service Reference - All known service IDs
- Teleprompter Protocol - Text display implementation (Work in Progress)
- proto/ - Protobuf definitions for payload encoding
- Type: CRC-16/CCITT
- Init: 0xFFFF
- Polynomial: 0x1021
- Scope: Calculated over payload bytes only (skip 8-byte header)
- Format: Little-endian
[AA] [21] [seq] [len] [01] [01] [svc_hi] [svc_lo] [payload...] [crc_lo] [crc_hi]
The G2 uses a dual-channel design:
- Content Channel (0x5401): What to display (text, data)
- Rendering Channel (0x6402): How to display (positioning, styling)
Pull requests welcome! Areas needing research:
- Navigation turn-by-turn protocol
- Even AI request/response format
- Translation feature
- Display rendering commands (0x6402)
- Protocol research by the Even Realities community
