UniversalBle Explorer vs BlueTerm

UniversalBle Explorer is an open-source developer tool for discovering, connecting to and debugging Bluetooth Low Energy devices. Built on the universal_ble Flutter plugin, it offers a consistent experience across all platforms. SCAN & DISCOVER • Real-time scanning with a prominent scan button and a Start Scan prompt when no devices are found • Filter by service UUIDs, name prefix or manufacturer data, with saved presets that persist between sessions • Search devices by name or company name, resolved from Bluetooth SIG company identifiers • Sort by RSSI, last seen or name • View RSSI, the last advertisement and a live advertisement list that flashes as new packets arrive • Scanning continues while you inspect a device • Inspect devices already connected at system level on supported platforms CONNECT • One-tap connect and disconnect with live connection state • Optional autoConnect for automatic reconnection • Multiple simultaneous connections SERVICES & CHARACTERISTICS • Full GATT discovery with clear, human-readable output • Favorite services first, system services last • Property filter chips for read, write, notify, indicate and more • Text search by characteristic UUID, ignoring case and hyphens • Previous/next navigation between characteristics • Copy the complete service layout from the panel header READ, WRITE & SUBSCRIBE • Read characteristic values on demand • Write with or without response • Subscribe to notifications and indications, individually or for all at once • Live values in the log with timestamps GATT SERVER • Create, edit and manage GATT server profiles with services and characteristics • Run a peripheral server with advertising • Add or remove services at runtime • Import and export profiles as JSON DEVICE FINGERPRINT • Capture a complete fingerprint in one tap: 60 seconds of consolidated advertisements, discovered services, all readable values and a rolling-ID check after reconnecting • Copy the full report or stop the capture at any time LOGS & DIAGNOSTICS • Add custom log entries and clear individual entries • Auto-scroll to the newest entry, with a persisted toggle • Characteristic UUIDs included on read, write and error entries • Copy advertisements with an optional RSSI column • Detailed error codes and a configurable operation timeout POWER USER TOOLS • Command queue: Global, Per Device, Auto or None • Request a larger MTU for higher throughput • Pair and unpair devices with live pairing state • Guided permission flow and Bluetooth availability indicator BUILT FOR DEVELOPERS Whether you are building a BLE product, testing hardware, validating firmware or learning Bluetooth Low Energy, UniversalBle Explorer gives you the visibility and control you need. It is free, open source and built on the universal_ble plugin.

BlueTerm turns your phone into a bridge between a Bluetooth serial device and your computer's browser. Connect the device once on the phone, flip one switch, and any browser on the same Wi-Fi becomes a full terminal and live plotter for it. NEW IN 1.2.2 - Firmware update over Bluetooth (free) - update Zephyr / nRF Connect SDK (MCUboot) and ESP32 (experimental) devices with a file from your phone. The new image is test-booted, then confirmed, and rolls back if it fails to boot. - Two devices at once (Pro) - connect a sensor and a controller together, see both logs and send to either one; side by side on tablets. - AI agent test loops - an MCP agent can send and wait for the reply, stop on a failure line, wait until a value meets a condition and run multi-step tests in one call (Pro). KEY FEATURES - Browser Bridge - one switch serves a terminal and a live plot to any browser on your Wi-Fi. No cable, no driver, nothing to install on the computer. - BLE (Bluetooth Low Energy) - Nordic UART devices connect automatically, and a built-in GATT explorer lets you pick the notify and write characteristics yourself when a device uses its own UUIDs. - A terminal that reads like one - timestamps, hex view, selectable line endings (LF / CRLF / CR / none) and one-tap command macros. - Live plotting - numbers your device sends (temp:23.5, rpm=1200, >speed:3.14 or plain CSV) are charted in real time, in the app and in the browser. - Export what you captured - CSV or JSON through the share sheet, so it lands in iCloud Drive, Google Drive or anywhere you choose. - Try it without hardware - a built-in simulator streams sample sensor data, so you can see the whole flow before you own a device. NEW IN 1.2 - AUTOMATION AND AI AGENTS - AI coding agents (MCP) - turn on MCP on the Bridge screen (open it from the terminal's top bar) and an MCP client on your computer, such as Claude Code or Cursor, can read the live log and channel values over the same Wi-Fi (free). With Pro it can also send commands to the device. MCP is off by default, needs its own key and works while BlueTerm is open. - Auto-reply rules and send sequences - reply to a matching line automatically, or send a list of commands with delays and repeats. Free: 1 rule and 1 sequence; Pro: 10 of each. - Trigger capture - when a value crosses a threshold or a pattern appears, the lines before and after are saved for review and export. Free: 1 trigger and 3 saved captures; Pro: 10 triggers and 100 captures. - Long recording (Pro) - write the whole session to files of up to 50 MB each, keeping the latest 20. - Session history - every connection is recorded on the device automatically: all received and sent lines with timestamps. Search it, share it as TXT or CSV, or delete it. Free keeps the last 5 sessions, Pro keeps 100. - Commands sent by a rule or an agent are marked in the phone and browser terminals. BlueTerm Pro is a one-time lifetime purchase, not a subscription. It also removes ads and raises the scrollback, macro and browser limits. WHY THIS APP? Every other Bluetooth serial app ends inside the phone screen. But the work - reading long logs, comparing graphs, copying values into your notes - happens on a computer, and computers have no standard way to open a Bluetooth serial port. Access to the bridge is protected by a password you set yourself, with a lockout after repeated failures, and the address is served on your local network only.
