MQTT
A lightweight publish-subscribe messaging protocol designed for IoT devices with limited bandwidth and unreliable networks. MQTT uses a broker-based architecture where devices publish messages to topics and subscribe to topics of interest.
Why It Matters
MQTT is the dominant protocol for IoT communication due to its small packet overhead, quality-of-service levels, and persistent sessions that handle disconnections gracefully. In robotics, MQTT connects devices to cloud platforms for telemetry, commands, and configuration.
How Roboticks Implements It
Roboticks uses AWS IoT Core MQTT for all device-to-cloud communication. Devices authenticate with X.509 certificates and communicate over TLS 1.3-encrypted channels. The SDK handles connection management, reconnection, and message queuing transparently.
