Drive Even Realities G2 glasses yourself - no Even app, no cloud. OpenEvenSdk is a local-first toolkit for putting your own content on the G2 lens over Bluetooth, straight from a device you control.

|---|---|
claude-glass-bridge/ |
Python (Mac/PC). Mirrors your live Claude Code sessions onto the glasses: it reads Claude Code's own transcripts and serves them over a small HTTP API. bridge.py = read-only mirror (Python stdlib only); bridge_sdk.py = read/write, which owns SDK-managed sessions so you can spawn / dictate / approve from the glasses. Tested on real hardware. |
ios/ |
A SwiftUI iPhone app that connects both G2 arms over BLE and renders on the lens (and runs a small local HTTP server for pushing text/images directly). |
android/ |
A Kotlin/Compose port of the glasses app. Not yet device-tested. |
PROTOCOL.md |
The G2 BLE wire protocol - the byte-accurate source of truth the apps implement. |
# read-only mirror of your Claude Code sessions (no dependencies):
python3 claude-glass-bridge/bridge.py
# or read/write (spawn / dictate / approve from the glasses):
pip install -r claude-glass-bridge/requirements.txt
CLAUDE_GLASS_CWD=/path/to/repo python3 claude-glass-bridge/bridge_sdk.pyIt prints a URL + token; put both into the app's Settings screen. The phone and the computer running the bridge must be on the same Wi-Fi.
See ios/README.md and android/README.md
for building and pairing. The app owns the BLE link to both arms and speaks the
protocol in PROTOCOL.md.
- The G2 is two BLE peripherals (one per arm). Text goes to both; the EvenHub container/image channel goes to the right arm only.
- Connect, send a fixed 7-packet auth handshake, then a ~1.5 s heartbeat keeps the link alive.
- Text: a paged "teleprompter" flow (25 cols x 10 lines).
- Images / rich UI: the EvenHub protocol - declare containers, then stream a 4-bpp grayscale BMP tiled into a 2x2 grid across the 576x288 lens.
- Everything is CRC16/CCITT-framed in a simple
0xAA 0x21 ...envelope.
Full byte layout, field numbers, and timing are in PROTOCOL.md.
- claude-glass-bridge - working, tested on real G2 glasses. (
bridge.pyis stdlib-only;bridge_sdk.pyneedsclaude-agent-sdkand theclaudeCLI on PATH.) - iOS - tested on real G2 glasses.
- Android - ported from the protocol spec, not yet compiled or device-tested.
The G2 BLE protocol is reverse-engineered from community work - see the Credits
section in PROTOCOL.md and the per-file headers.
