LogCat Analyzer vs u

LogCat Analyzer: Debug Toolkit Analyze log data directly on your iPhone or iPad. Detect crashes, performance issues, and bugs — no computer required. INTELLIGENT ISSUE DETECTION Instantly detect 6 types of issues from log data: • Crashes — NullPointerException, IndexOutOfBounds, Fatal Signals • ANR — Application Not Responding with root cause • Memory Pressure — GC thrashing, low memory, OutOfMemory • Network Errors — timeouts, DNS failures, SSL errors, HTTP 4xx/5xx • StrictMode Violations — disk/network on main thread, dropped frames • Infinite Loops — repeated error patterns and retry storms Each issue includes a severity badge, occurrence count, root cause explanation, and suggested troubleshooting steps. EXPLAIN & FIX Tap any issue to get a clear explanation: • What happened and why • Likely root cause based on stack trace analysis • Suggested troubleshooting steps • One-tap Google search or AI-assisted insights for deeper help CRASH ANALYSIS • Visual crash timeline with expandable stack traces • Crash summary with severity assessment (Low → Critical) • Group crashes by exception type with occurrence counts • Copy stack traces or export crash reports INSIGHTS DASHBOARD • Log level distribution chart • Device metadata (model, OS version, device type, emulator detection) • File overview with error/warning counts • Quick navigation to crash timeline and summary LOG EXPLORER • Smart context-aware highlighting: red for crashes, blue for lifecycle, yellow for warnings, cyan for network • Search by text, package name (package:), or tag (tag:) • Filter by log level (V/D/I/W/E/A) • Bookmark entries, multi-select, and export as .logcat or .txt • Fullscreen mode, adjustable font size, text wrap toggle • Save and apply filter presets BUILT FOR DEVELOPERS • Import .logcat files from Files app or share sheet • 7 languages: English, Vietnamese, Chinese, Japanese, Korean, French, Russian • Dark and light theme • Works completely offline — your data stays on device

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.
