Serial Terminal : USB and BLE

Serial Terminal : USB and BLE is a modern, high-performance serial monitor and debugging console engineered for developers, makers, and embedded systems engineers. Connect seamlessly to Arduino, ESP32, ESP8266, Raspberry Pi Pico, STM32, microcontrollers, and wireless modules over USB OTG, Bluetooth Classic (SPP), Bluetooth Low Energy (BLE GATT UART), and local WiFi TCP sockets. ✦ ALL-IN-ONE HARDWARE TRANSPORTS 1. USB SERIAL (UART): • Direct USB OTG host communication with popular USB-to-UART bridge chipsets. • Supported drivers: FTDI (FT232R, FT2232), Silicon Labs CP2102/CP2104, Prolific PL2303, WCH CH340 / CH341, and standard USB CDC ACM devices. • Baud rates from 300 to 921,600 bps with customizable data bits (5–8), stop bits (1, 1.5, 2), parity (None, Odd, Even, Mark, Space), and flow control (RTS/CTS, DTR/DSR, XON/XOFF). • Hardware modem line controls: Toggle DTR and RTS; monitor real-time CTS, DSR, CD, and RI states; trigger Send BREAK. 2. BLUETOOTH CLASSIC (SPP): • Connect to HC-05, HC-06, and standard Bluetooth Serial Port Profile (SPP) modules. • Fast discovery of paired and nearby Bluetooth devices with reliable background RFCOMM socket handling. 3. BLUETOOTH LOW ENERGY (BLE GATT): • Dedicated BLE GATT client with automatic MTU negotiation (up to 512 bytes) and CCCD notification subscriptions. • Built-in profiles: Nordic UART Service (NUS), TI / HM-10, Microchip RN4870, and custom service/characteristic UUIDs. • Live RSSI signal monitoring and chunked write buffering. 4. WIFI / ETHERNET TCP SOCKET: • Low-latency TCP socket client (TCP_NODELAY, keep-alive) for microcontrollers connected to LAN or running SoftAP. • Instant one-tap presets for ESP32 and ESP8266 default access points (192.168.4.1:8080). ✦ PROFESSIONAL TERMINAL ENGINE • Live Monospace Display: Color-coded RX/TX direction markers, millisecond timestamps, and line numbers. • Dual Display Modes: Seamlessly switch between Text (ASCII/UTF-8) and raw HEX byte dumps. • Non-Destructive Pause: Freeze terminal rendering to inspect live logs without dropping incoming hardware packets. • In-Buffer Search: Instant text filtering with match highlighting across thousands of buffered lines. • Pinch-to-Zoom Scaling: Dynamically adjust terminal font size from 10sp to 24sp. • Custom Line Endings: Support for CR+LF (\r\n), LF (\n), CR (\r), or None. • HEX Input Mode: Send raw binary bytes formatted as "0xAA 0x55" or clean hex streams. ✦ AUTOMATION & EMBEDDED TOOLS • Command Macros: Save parameterized AT commands, sensor calibration payloads, and frequent commands. • Multi-Step Sequences: Execute automated command workflows with configurable delays (ms) and loop counts. • Auto-Repeat Pinger: Continuously transmit periodic packets (100ms – 60s) with safety iteration limits. • Side-by-Side HEX Inspector: Inspect packet buffers with address offsets, 16-byte hex dumps, and ASCII previews. • Hardware Profiles: One-tap connection presets for Arduino Uno/Mega, ESP32, HC-05, and Nordic BLE. • Session Logging: Export logs directly to TXT, CSV, or raw binary (.bin) files. ✦ 100% PRIVATE & OFFLINE-READY Serial Terminal : USB and BLE operates locally. Your serial packets, Bluetooth data, sensor readings, and logs remain strictly on your physical Android device. Active background connections are kept persistent via an Android Foreground Service. *Note: USB serial functionality requires an Android device with USB Host (OTG) support and an OTG cable/adapter.*
