RAIOTerm: Arduino ESP Control+

RAIO TECH

About this app

RAIOTerm is the universal hardware bridge, advanced serial monitor, and interactive IoT dashboard platform built for developers, embedded engineers, and makers. Replacing traditional apps, RAIOTerm connects your Android device directly to your microcontrollers to visualize sensor data, control hardware, and debug projects in real-time.

Whether prototyping a smart home ecosystem with an ESP32, NodeMCU, or ESP8266, debugging an Arduino robotics project via USB OTG, or monitoring industrial sensors over local TCP/IP networks, RAIOTerm provides a custom dashboard and terminal right in your pocket.



🔌 UNIVERSAL CONNECTIVITY & PROTOCOLS

Stop downloading separate apps. RAIOTerm is an all-in-one hardware testing tool:
• Bluetooth Low Energy (BLE): Scan, connect, and subscribe to BLE characteristics. Perfect for modern low-power IoT devices.
• Bluetooth Classic (SPP): Communicate seamlessly with legacy serial modules like the HC-05 and HC-06.
• USB Serial Terminal: Connect directly via a USB OTG cable. Supports FTDI, CH340, and CP2102 for zero-latency serial monitoring.
• TCP/IP Sockets: Connect to local servers, remote IoT brokers, or WiFi modules over your network.



🎨 35+ INTERACTIVE DASHBOARD WIDGETS

Build stunning interfaces without writing front-end code. Map incoming data to specific command IDs and visualize your project instantly:
• Controls: Buttons, Toggle Switches, Sliders, Joysticks, D-Pads, Steppers, Dropdowns, and Light Dimmers.
• Displays & Indicators: Gauges, LED Indicators, Liquid Levels, Battery Meters, and Segment Displays.
• Data Tracking: Advanced Live Graphs, Data Tables, Map integrations, and Value Displays for precise plotting and data tracking of any particular widget stream.
• Device Inputs: Utilize your phone's Mobile Sensors, Camera Feeds, and Text Inputs as hardware triggers.



📊 ADVANCED SERIAL MONITOR & TERMINAL

• Pro Terminal Features: Auto-scroll, timestamping, hex-view, and color-coded inbound/outbound traffic.
• Command Execution: Send JSON commands, raw ASCII text, or Hexadecimal arrays directly to your boards.



🔔 TELEGRAM & DISCORD WEBHOOKS

Take your IoT automation to the next level natively. Trigger automated alerts, status updates, and messages directly from your hardware to your favorite Discord servers and Telegram chats using our built-in webhook setup!
