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