u-connectXplorer
BLE companion for u-blox
Free · Designed for iPad. Not verified for macOS.
Companion app for u-blox u-connectXpress modules. BLE scan & connect, SPS/NUS serial console, GATT browser, MQTT, sockets, and OTA — built by u-blox engineers.
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.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New in 1.1.3:
• Fixed the app closing immediately at launch on iOS 15–17 (e.g. iPhone 7, iPhone 8, iPhone X). iOS 15 or later is supported again
New in 1.1.2 — stability release:
• Dice Demo no longer slows down during long sessions — the live advertisement feed is now registered once and cleaned up properly
• Fixed memory leaks in BLE scanning and device reconnection: Service Changed subscriptions and advertisement history are now released when a device disconnects or goes stale
• Fixed leaks in the ALMA Demo location stream, the Auracast scanner and Wi-Fi Provisioning
• Steadier performance and lower memory use across long scans and repeated connects
