BLE tools with terminal vs Device Protocol Studio

A practical BluetoothLE scanning tool that can connect to BLE Bluetooth devices to obtain information, supports terminal mode, and can set function keys. It is a very convenient tool for developers of Arduino or Raspberry pie. Support the reminder function of Bluetooth device [online]. When the stored Bluetooth device is scanned, a reminder will appear. The distance can be judged by the value of rssi. If there is a Bluetooth headset forgotten where to put it, you can use this function to find . There is also an interesting application method for this function. For example, put the Bluetooth headset in the suitcase when going abroad. When the suitcase turntable sends the luggage out, the mobile phone will remind the user that the luggage is here!

Device Protocol Studio (DPS) is a professional communication, protocol development, and testing toolkit built for embedded developers, firmware engineers, hardware engineers, and IoT developers. Connect to real hardware, simulate virtual devices, design custom protocols, monitor live data, and build repeatable test workflows — all from your iPhone. SUPPORTED COMMUNICATION • Bluetooth Low Energy (BLE) • TCP Client / Server • UDP • MQTT • WebSocket • HTTP / REST • CoAP DEVICE COMMUNICATION Connect to real devices and inspect communication in real time. • BLE scanning and connection • GATT service and characteristic exploration • Read, Write, and Notify operations • Dynamic RX / TX characteristic binding • TCP, UDP, MQTT, WebSocket, HTTP, and CoAP communication • Real-time terminal with ASCII, text, and binary workflows REAL-TIME DATA & PLOTTING Turn incoming device data into live engineering telemetry. • Multi-channel real-time plotting • Live CSV / ASCII data monitoring • High-speed data updates • Session logging and data export • Real-time RX / TX monitoring PROTOCOL DESIGNER Build and test your own communication protocols directly on your device. • Custom packet field definitions • Header and footer fields • Length and opcode fields • Payload configuration • CRC and checksum support • Custom field ordering • Reusable protocol presets VIRTUAL DEVICES Test communication workflows even when physical hardware is not available. • Built-in virtual device environment • BLE virtual device testing • TCP / UDP virtual communication • Simulated sensor data • Rapid protocol and UI verification TEST STUDIO Create repeatable communication tests for device and protocol development. • Command and response testing • Expected-response validation • Automated test sequences • Timeout and failure detection • Reusable test scenarios BUILT FOR ENGINEERS DPS is designed to reduce the number of separate tools needed during embedded and IoT development. Use one workspace to connect, inspect, design, simulate, plot, log, and test your device communication. PRIVACY-FIRST Your engineering data stays under your control. DPS is designed around local workflows without requiring external cloud synchronization for core development and testing. Whether you are debugging a BLE peripheral, testing a TCP device, designing a binary protocol, monitoring sensor telemetry, or validating command/response behavior, Device Protocol Studio gives you a portable engineering workspace directly on your iPhone.
