Connect to BLE devices, AI explains the data streams

The Problem

BLE device data is cryptic and documentation is often missing or wrong

Current Solutions (Not Great)

nRF Connect (raw data), reading spec sheets, trial and error

Who Needs This

IoT developers, hardware hackers, fitness device tinkerers, smart home enthusiasts

Bluetooth Low Energy devices stream cryptic data that's hard to interpret without documentation. Bluetooth Diagnostics connects to any BLE device, shows you the raw data streams, and uses AI to help interpret what the numbers mean. Perfect for IoT developers, fitness device hackers, and anyone trying to understand what their smart devices are actually broadcasting.

Honest Take

Very niche—IoT developers and hardware hackers are a small but passionate audience. nRF Connect is the standard but has a learning curve. The AI interpretation angle is genuinely novel and useful. Web Bluetooth support is limited (Chrome only, and many devices won't connect). Best for developers already frustrated with BLE debugging.

Build Prompt

Use this prompt with an AI assistant to start building

Build a React PWA called 'Bluetooth Diagnostics' using WebInfer and Web Bluetooth API. UI: 'Scan Devices' button, device list, connected device panel with services/characteristics tree, live data stream graph. Use navigator.bluetooth.requestDevice() with acceptAllDevices for scanning. Connect and enumerate services via device.gatt.connect(). For each characteristic, show UUID, properties, current value. Subscribe to notifications for live updates. Display raw bytes + attempted ASCII/number interpretation. Use generateObject with context: { serviceUUID: string, characteristicUUID: string, values: number[], pattern: string } to return { likelyMeaning: string, protocol: string, fields: [{ bytes: string, interpretation: string }], confidence: number, documentation?: string }. Live graph of numeric values over time (Chart.js). Export log as CSV.
