UniversalBle Explorer vs BT/BLE Scanner

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.

Bluetooth Scanner turns your iPhone into a Bluetooth Low Energy explorer. Scan the environment, save the devices you care about, and inspect everything they broadcast — right down to the raw advertisement data. No cloud, no account, no internet connection needed: everything happens locally, straight from your device's Bluetooth hardware. FEATURES • Live scan of nearby Bluetooth LE devices, sorted by signal strength • Save devices to your list and give them your own nicknames • Swipe to remove a saved device at any time • Full detail view per device: signal strength (RSSI), TX power, MTU, connectable state, service UUIDs, manufacturer data, and more • Automatic background refresh keeps saved devices' signal strength and data up to date while you're on the Home screen • On-demand decoding of common BLE beacon formats — iBeacon, Eddystone, and Apple Continuity — shown as readable fields instead of raw hex • Export your saved device list as a JSON file via the share sheet • Scan preferences: auto-stop timer, hide unnamed devices, minimum signal strength filter — all remembered between launches • Dark mode by default, with a light mode toggle — your choice is remembered too • Fully offline operation, no tracking, no analytics PRIVACY Bluetooth Scanner does not collect, transmit, or store any data outside your device. Scanned and saved devices exist only for your current session; only your display preferences (theme and scan filters) are remembered locally on your device.
