# open-g2-hub: a local Even G2 client built on BLE protocol findings

> open-g2-hub replaces the Even Realities G2 companion app with a local hub for native widgets and voice input on stock firmware. Its protocol notes describe dual-lens BLE characteristics, an AA 21 control frame, CRC-16 checksums, service IDs, heartbeats and LC3 microphone data.
