BLE scanner & server for devs
Free · Designed for iPad. Not verified for macOS.
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
