MQTT-SN specification

MQTT-SN (Message Queuing Telemetry Transport for Sensor Networks) is a lightweight messaging protocol designed for communication between devices in networks with limited resources, such as sensors and IoT devices. It simplifies data exchange by using small message sizes and streamlined communication methods, making it ideal for environments with constrained bandwidth, power, or processing capabilities. MQTT-SN extends the standard MQTT protocol to work efficiently over non-Internet networks like Zigbee or Bluetooth, focusing on low power consumption, ease of deployment, and reliable message delivery in sensor and device networks.
