Ble Agent Gateway

BLE Agent Gateway

An AI-powered control layer for BLE devices. Runs on a Raspberry Pi (or any machine with Bluetooth), monitors sensors, detects device presence, reacts to events, and acts autonomously — no rules engine, no rigid automation. Just tell it what you want.

Connects to BLE hardware via the [BLE MCP Server](https://github.com/es617/ble-mcp-server). Exposes itself as an MCP server so you can chat with it from Claude Desktop, Claude mobile, or any MCP client.

Built with [fast-agent](https://github.com/evalstate/fast-agent).

What it does

The gateway has two agents:

**Controller** (autonomous, uses Sonnet) — the brain:

• Receives BLE notifications in real time
• Creates and manages plugins for continuous monitoring
• Writes and fixes its own code — verifies plugins work, debugs when they don't
• Stores all events and rules in a SQLite database
• Acts on rules set by the user

**User agent** (interactive, uses Haiku) — the interface:

• Presents data to the user (queries database)
• Passes user instructions to the controller in plain language
• Handles one-off BLE operations (quick scans, reads)
• Explains what happened and who did what
