UniversalBle Explorer vs BLE Insight

UniversalBle Explorer is an open-source developer tool for discovering, connecting to and debugging Bluetooth Low Energy devices. Built on the universal_ble Flutter plugin, it offers a consistent experience across all platforms. SCAN & DISCOVER • Real-time scanning with a prominent scan button and a Start Scan prompt when no devices are found • Filter by service UUIDs, name prefix or manufacturer data, with saved presets that persist between sessions • Search devices by name or company name, resolved from Bluetooth SIG company identifiers • Sort by RSSI, last seen or name • View RSSI, the last advertisement and a live advertisement list that flashes as new packets arrive • Scanning continues while you inspect a device • Inspect devices already connected at system level on supported platforms CONNECT • One-tap connect and disconnect with live connection state • Optional autoConnect for automatic reconnection • Multiple simultaneous connections SERVICES & CHARACTERISTICS • Full GATT discovery with clear, human-readable output • Favorite services first, system services last • Property filter chips for read, write, notify, indicate and more • Text search by characteristic UUID, ignoring case and hyphens • Previous/next navigation between characteristics • Copy the complete service layout from the panel header READ, WRITE & SUBSCRIBE • Read characteristic values on demand • Write with or without response • Subscribe to notifications and indications, individually or for all at once • Live values in the log with timestamps GATT SERVER • Create, edit and manage GATT server profiles with services and characteristics • Run a peripheral server with advertising • Add or remove services at runtime • Import and export profiles as JSON DEVICE FINGERPRINT • Capture a complete fingerprint in one tap: 60 seconds of consolidated advertisements, discovered services, all readable values and a rolling-ID check after reconnecting • Copy the full report or stop the capture at any time LOGS & DIAGNOSTICS • Add custom log entries and clear individual entries • Auto-scroll to the newest entry, with a persisted toggle • Characteristic UUIDs included on read, write and error entries • Copy advertisements with an optional RSSI column • Detailed error codes and a configurable operation timeout POWER USER TOOLS • Command queue: Global, Per Device, Auto or None • Request a larger MTU for higher throughput • Pair and unpair devices with live pairing state • Guided permission flow and Bluetooth availability indicator BUILT FOR DEVELOPERS Whether you are building a BLE product, testing hardware, validating firmware or learning Bluetooth Low Energy, UniversalBle Explorer gives you the visibility and control you need. It is free, open source and built on the universal_ble plugin.

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.
