UniversalBle Explorer vs HelloBlue

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.

HelloBlue turns your iPhone or iPad into a Bluetooth Low Energy (BLE) debugging tool. Scan nearby devices, connect in a tap, explore every service and characteristic, send data, and watch the traffic live, all in one clean app. Built for firmware engineers, IoT developers, testers, and hardware makers who need to inspect and talk to BLE devices quickly. KEY FEATURES - Scan and connect Discover nearby BLE devices with live signal strength (RSSI). Search by name or UUID, sort by name or signal, rename devices, and reconnect to recent devices automatically. - Services and characteristics Browse every GATT service and characteristic. Read values as hex and text, write data, and subscribe to notifications. Give services and characteristics names that make sense to you. - Send data your way Send in Hex, String, or JSON. Save frequently used commands as quick texts and resend them with one tap. - Live operation logs Watch reads, writes, notifications, and errors stream in real time from any screen. Filter entries and turn auto-scroll on or off. - Session history Every session and automation run is saved. Review past logs, rename them, export them to share with your team, or delete what you no longer need. - Automation workflows Chain connect, write, delay, and loop steps into reusable flows. Set message intervals and repeat counts, and choose whether each step stops or continues on failure. - Location history HelloBlue records where a device was each time it connects, making it easier to find again. - iPhone and iPad Works on both, with layouts designed for each screen. Bluetooth must be turned on, and HelloBlue needs Bluetooth permission to scan and connect. Location history requires location permission. Some features depend on the services and characteristics your device provides.
