QR Code Tool Master vs Bluelyze

QR Code Tool Master is a powerful QR code and barcode scanning tool. Whether scanning through the camera or selecting from the gallery, you can quickly obtain scan results and save them for later reference in the scan history.

Your BLE devices are talking. Bluelyze lets you listen. Bluelyze is a professional Bluetooth Low Energy toolkit built for iOS developers, hardware engineers, and IoT tinkerers who need real insight into the wireless world around them — without connecting a laptop. -- SCAN & DISCOVER -- Detect nearby BLE peripherals instantly. Live signal-strength bars, device-type detection, manufacturer identification, and a built-in advertisement logger that captures every broadcast in real time. -- GATT BROWSER -- Connect to any BLE device and explore its complete GATT profile: services, characteristics, and descriptors. Read, write, and subscribe to notifications on any characteristic. Bookmark frequently used services with custom names. -- MULTI-DEVICE CONNECTIONS -- Connect to up to 4 devices at the same time and monitor their characteristic dashboards side by side. Ideal for comparing sensor nodes, debugging multi-peripheral setups, or stress-testing firmware. -- PROXIMITY FINDER -- Track down a specific device using RSSI-based proximity guidance. Real-time visual feedback gets you to the hardware without guesswork. -- BEACON DETECTION -- Decode iBeacon and Eddystone beacons in full: UUID, major, minor, TX power, and frame type. Verify deployments and audit proximity zones on the spot. -- PERIPHERAL EMITTER -- Turn your iPhone into a BLE peripheral. Broadcast custom GATT services and characteristics to test your apps, SDKs, or hardware integrations without a second device. -- MQTT & WEBHOOK PUSH -- Push characteristic data to any MQTT broker or HTTP webhook endpoint. Wire Bluelyze into your cloud pipeline, home-automation hub, or IoT dashboard — no code required. -- EXPORT & SHARE -- Export advertisement logs and device data as CSV or JSON. Share with teammates, import into analysis tools, or archive for compliance. WHAT MAKES BLUELYZE DIFFERENT - 4 simultaneous connections vs. 1 in most BLE apps - Advertisement logger with real-time capture (rare in this category) - MQTT + webhook push built in, not as paid add-on - BLE peripheral emitter included in the free tier - 44 languages supported out of the box BUILT FOR Embedded firmware developers testing BLE hardware IoT engineers building connected products QA teams verifying beacon deployments Home-automation enthusiasts integrating BLE sensors Students and hobbyists exploring Bluetooth technology Bluelyze is the BLE workbench that fits in your pocket — and now on your Mac too, via Mac Catalyst.
