Communication Protocols

Specification of all communication interfaces — BLE services, MQTT topics, REST APIs, UART protocols — with message formats, error handling, and sequence diagrams.

Why It Matters

Communication bugs between devices, apps, and cloud services are painful to debug. A clear protocol specification eliminates ambiguity and enables parallel development.

What's Included

Protocol overview
Message formats
Sequence diagrams
Error handling
Retry and timeout policies
Security considerations

How It's Generated

1

AI Research

Gemini with Google Search Grounding researches current SDK documentation, API references, and best practices for your specific hardware platform.

2

Document Generation

GPT-5.1 generates a comprehensive Protocols Doc using the research context, tailored to your project requirements and hardware.
