u vs ByteSniffer

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.

ByteSniffer is a professional network debugging tool designed for iOS developers, QA engineers, and networking professionals. It supports real-time capture and analysis of HTTP/HTTPS, SSE, WebSocket, TCP, and UDP traffic. You can inspect request headers, response content, real-time messages, bidirectional raw data, and data in multiple formats including Hex, Text, and JSON. ByteSniffer also provides useful tools such as Host filtering, capture history, full-text search, sharing and export, request replay, content rewriting, breakpoints, and JavaScript scripting. These features help you quickly troubleshoot API errors, connection issues, and data transmission problems. HTTPS and WSS traffic analysis requires installing and trusting the MITM certificate provided by the app. Some advanced features require Pro access. Please use ByteSniffer only with applications and network environments that you own or are authorized to test. Membership Purchase: Unlock permanent access for only CNY 19.9, including MITM, HTTPS, SSE, WebSocket, TCP, UDP, Replay, Rewrite, Breakpoints, and Scripts — for about the price of a cup of milk tea.
