RaioLink provides the official connectivity layer for RaioTerm "Pair" devices. It abstracts away the complex binary framing (0xC0 protocol) and provides a simple Chat-like interface for your microcontroller.

• ESP32 (All variants)
• ESP8266 (NodeMCU, D1 Mini)
• Raspberry Pi Pico W (Arduino Core)

1. #include <RaioLink.h>
2. Create object: RaioLink link(mqttClient);
3. Setup: link.begin("pair_123", 'A');
4. Loop: link.join() inside your MQTT reconnect block.
