Universal BLE vs BLE Debugger

Universal BLE is an open-source developer tool for exploring and testing Bluetooth Low Energy (BLE) devices. It empowers developers, engineers, and hobbyists to discover, connect, and debug BLE devices with a consistent cross-platform experience. Key Features Device Discovery Real-time scanning — Discover nearby BLE devices with live results; scanning continues when you open a device's detail screen Flexible filters — Filter by service UUIDs, name prefix, or manufacturer data (comma- or newline-separated) Saved filter presets — Save, rename, and reuse filter combinations; filters persist across app sessions Search — Search devices by name or by company name (resolved from manufacturer data via Bluetooth company identifiers) Sort options — Sort the device list by RSSI, last seen, or name Company identification — Show company name from manufacturer data using the Bluetooth SIG company identifier list RSSI and advertisements — View signal strength (RSSI), last advertisement (name, RSSI, timestamp), and a list of received ads that flashes on new advertisements System devices — On supported platforms, view and connect to devices already connected at the system level (with optional service filter) Connection Management Connect and disconnect — Connect to and disconnect from BLE peripherals with one tap Auto-reconnect — Optional auto-connect for reconnection when a device becomes available again Connection state — Real-time connection state updates Multiple connections — Support for multiple simultaneous device connections Service & Characteristic Exploration GATT discovery — Discover all services and characteristics on connected devices with detailed, human-readable formatting Favorite services — Mark services as favorites; they appear first in the list (system services last) Property filters — Filter characteristics by property (read, write, notify, indicate, etc.) with visual filter chips Navigation — Previous/next buttons to move between characteristics without collapsing the list Copy services — Copy the full discovered GATT layout (e.g. for documentation or debugging) from the Services panel header Data Operations Read — Read characteristic values on demand Write — Write data to characteristics (with or without response) Subscribe — Subscribe to notifications/indications per characteristic or "subscribe to all" for notifiable characteristics Live updates — Incoming values are shown in the logs with timestamps; clear or copy the full log Pairing & Security Pair and unpair — Initiate pairing and unpair devices when supported Pairing state — Monitor pairing state changes in real time Advanced & Developer Options MTU — Request a larger MTU (e.g. 247) for better throughput where supported Command queue — Choose queue type in the drawer: Global (single queue), Per Device, or None (parallel) Configurable timeout — Set operation timeout (e.g. 10 seconds) for all BLE operations Logs — Operation log with copy-all and per-entry clear; comprehensive error handling with detailed codes UUID formats — Accepts common UUID string formats (e.g. with or without hyphens) UI & Cross-Platform Responsive layout — Adapts to mobile, tablet, and desktop (e.g. breakpoints at 600px and 1000px) Bluetooth status — Bluetooth availability icon with tooltip (tap on mobile to see state) Permissions — Guided permission flow where required (e.g. location for BLE on Android); re-checks on app resume Cross-platform — Built with the universal_ble plugin for consistent behavior across supported platforms Perfect For Developers building BLE-enabled applications Engineers testing and debugging BLE devices Hobbyists exploring IoT and smart device capabilities Students learning about Bluetooth Low Energy technology QA teams validating BLE device functionality

# Bluetooth Debugger — Connect, Test and Automate BLE Devices Faster Stop switching between multiple tools to debug Bluetooth devices. Bluetooth Debugger helps you discover devices, inspect GATT services, exchange data in real time, and automate repetitive testing — all in one place. Whether you're developing IoT hardware, validating firmware, debugging communication issues, or reverse-engineering BLE behavior, Bluetooth Debugger helps you move faster. # Debug Devices in Minutes, Not Hours Connect to nearby BLE devices and immediately inspect services, characteristics, and live data. No extra setup. No custom test tools. • Scan and identify nearby devices • View device information and signal strength • Explore services and characteristics • Read and monitor characteristic values live # Turn BLE Communication Into a Real Conversation Testing BLE should not feel like editing raw packets. Session Mode lets you interact with devices like a terminal: • Send and receive messages in real time • Save frequently used commands • Continuously send test data automatically • Validate responses instantly # Automate Repetitive Testing Stop repeating the same read → write → wait → read sequence. Create automation flows and run them with one tap. Perfect for: • Device validation • Firmware debugging • Regression testing • Factory and development workflows # Understand What Happened Capture logs and export data for later analysis. Track device interactions and troubleshoot issues with confidence. # Built for People Who Work With BLE Developers · QA Engineers · IoT Builders · Embedded Engineers · Hardware Teams Connect faster.
