Binary Protocol

bitchat uses an efficient binary protocol optimized for Bluetooth LE:

• Compact packet format with 1-byte type field
• TTL-based message routing (max 7 hops)
• Automatic fragmentation for large messages
• Message deduplication via unique IDs

Mesh Networking

• Each device acts as both client and peripheral
• Automatic peer discovery and connection management
• Store-and-forward for offline message delivery
• Adaptive duty cycling for battery optimization
