About this app

Xiao – Universal Device Communication Hub

Xiao is an all-in-one tool designed for developers, engineers, and makers to connect, test, and interact with a wide range of devices and communication protocols from a single app.

The app supports Bluetooth Low Energy (BLE) and classic Bluetooth for scanning, connecting, and exchanging data with nearby devices. It also provides powerful Wi-Fi networking capabilities including TCP and UDP sockets, WebSocket communication, and mDNS discovery for seamless local network integration.

For IoT workflows, Xiao includes MQTT support, allowing you to connect to brokers and send or receive messages in real time. You can also test and interact with HTTP APIs and WebSocket endpoints, making it useful for both local and cloud-based systems.

Xiao includes NFC support for scanning and interacting with NFC tags and compatible devices. The app features a clean and intuitive interface that allows quick setup and efficient data exchange.

Built with developers in mind, Xiao offers tools for payload customization, protocol selection, and real-time data monitoring, helping you debug and experiment with ease.

Xiao is ideal for IoT prototyping, embedded systems development, network and protocol testing, and general hardware communication tasks.
