## Description

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

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

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.
