Universal BLE vs BLE Insight

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

BLE Insight is a powerful Bluetooth Low Energy development tool designed for developers, engineers, and IoT professionals. Scan, connect, and communicate with any BLE device — all from your iPhone. Visualize every detail of BLE communication with real-time sequence diagrams, live RSSI monitoring, and interactive data graphs. KEY FEATURES • Device Scanner Discover nearby BLE devices instantly. View device names, RSSI signal strength, and detailed advertisement data including service UUIDs, manufacturer data, and TX power. • Service & Characteristic Explorer Browse all services and characteristics of connected devices. Read, write, and subscribe to characteristics with a single tap. Supports Hex, UTF-8, and Decimal data formats. • Real-Time Sequence View Watch BLE communication unfold in real time. Every connection event, service discovery, read, write, and notification is displayed in a clear, chronological timeline. • RSSI Signal Monitor Track signal strength with a live-updating chart. View current, min, max, and average RSSI values at a glance with color-coded signal quality indicators. • Data Graphing & Logging Plot numeric characteristic values on real-time graphs. Supports standard integers, floats, and IEEE 11073 FLOAT formats. Export logged data as CSV. • Automated Test Scripts Record communication sessions and convert them into reusable test scripts. Create custom test sequences manually. Run scripts and verify each step with pass/fail results. • Beacon Scanner Detect iBeacon and Eddystone beacons nearby. View UUID, Major, Minor, proximity, and signal strength for each beacon. • Favorites & Session History Star your frequently used devices for quick access. All communication sessions are automatically saved and can be reviewed or exported anytime. • Connection Parameters View MTU sizes and connection details. Configure connection options including background notifications and auto-reconnect (iOS 17+). Built for professionals who need visibility into BLE communication. Whether you're developing firmware, debugging a sensor, or testing an IoT product — BLE Insight gives you the tools to understand what's happening over the air. Requires iOS 17.0 or later. Bluetooth 4.0+ (BLE) capable device required.
