u vs BLE Scope

u-connectXplorer is the official companion app for u-blox u-connectXpress wireless modules. It is built for engineers and developers evaluating, integrating, or debugging u-blox short-range modules. The app supports BLE Central (GATT Client), BLE Peripheral (GATT Server), socket terminals, MQTT, and OTA firmware update — all in one tool. SUPPORTED u-blox MODULES • NORA-W36 — Wi-Fi 4 + BLE 5.3 • NORA-B26 — BLE 6.0 • NORA-B27 — BLE 6.0 • NORA-B20 series — BLE 6.0 with DFU OTA BLUETOOTH CENTRAL • Scan with name, UUID, RSSI, and Resolvable Set Identifier filters • Full GATT browser — discover services, read, write, subscribe to notifications • GATT profile cards — Battery, Heart Rate, Device Information, Environmental Sensing, Current Time, Automation IO • MTU negotiation up to 247 bytes • Connection dashboard with live RSSI, MTU, and PHY information SERIAL CONSOLE • u-blox SPS (Serial Port Service) — credit-based flow control • Nordic UART Service (NUS) — bidirectional serial • Throughput tests with live kB/s chart (Echo, TX flood, RX, RTT) BLE PERIPHERAL (GATT SERVER) • Advertise SPS or NUS for module testing • Standard GATT profiles — Battery, Heart Rate, Environmental, Device Info, HID Keyboard, Current Time • Custom GATT service builder — define your own UUIDs and characteristics WI-FI TOOLS • Wi-Fi Provisioning over BLE (Nordic protocol) — configure modules wirelessly NETWORK & IoT TOOLS • Socket Terminal — TCP, UDP, TLS (client and server) with mutual-TLS support • TLS certificate manager — upload PEM certificates, build SecurityContext • MQTT 3.1.1 client — publish, subscribe, QoS, last will, TLS • Network diagnostics — ping with RTT chart and gateway detection, mDNS service discovery, iperf2 bandwidth test, network interface info FIRMWARE UPDATE OVER BLE • Nordic DFU OTA for nRF-based modules • SMP / mcumgr / SUIT OTA for nRF54 series (NORA-B20, B26, B27) • Firmware browser with version picker CHANNEL SOUNDING • Simulated distance demo with live chart, statistics, and CSV export • Live measurement requires an Android 16+ device with Bluetooth 6.0 hardware ADDITIONAL TOOLS • Protocol Analyzer — real-time BLE packet capture, hex + text payload, JSON/CSV export • Tracker detection — AirTag, SmartTag, Tile, Find My Device Network • BLE Chat — peer-to-peer messaging and collaborative drawing over SPS/NUS • Remote control API — JSON-RPC 2.0 WebSocket server for automation DEMOS • Dice Demo — a 3D dice mirrors a real ANNA-B5 die's motion in real time over BLE • ALMA Demo — asset tracking with the ALMA-B2 on-device NPU (drops, shakes, hits) and a map-linked event log • IMU Streamer — stream the phone's motion sensors over UDP, BLE GATT, or MQTT This app does not collect, store, or transmit any personal data. All wireless communication happens directly between your iPhone, your u-blox module, and the destinations you choose.

BLE Scope is a lightweight utility for anyone working with Bluetooth Low Energy hardware — firmware developers, integrators, and hobbyists who need to see exactly what a device is broadcasting and talk to it directly. SCAN - Real-time scan of nearby BLE peripherals with continuous RSSI updates. - Per-device RSSI history chart with a moving-average line, so you can watch signal behaviour as you move around. - Signal-strength grouping and sorting that stays readable while scanning. INSPECT ADVERTISEMENTS - Connectable flag, Tx power level, and advertised service UUIDs with well-known names resolved. - Hex dump of manufacturer-specific and service data, with the company identifier decoded. GATT - Connect to a peripheral and discover its services, characteristics, and descriptors. - Read characteristic values, with decoders for well-known characteristics. - Subscribe to notifications and indications with a rolling value log. - Write values as hex or text, with or without response. FAVORITES - Mark the peripherals you care about; favorites are stored on device and persist across sessions. BLE Scope has no account, makes no network connections, shows no ads, and collects no data. Scanning and connections run only while the app is in the foreground.
