[FEATURE] MQTT-SN support #2059
Description
Implementing MQTT-SN in the ThingsBoard IoT Gateway will significantly benefit both users and the overall ecosystem by bridging the gap between high-performance cloud backbones and power-constrained edge hardware.
Key Benefits for Users
- Drastic Power Savings: Users can deploy battery-powered sensors that utilize MQTT-SN’s native "Sleep Mode" and connectionless UDP transport, extending device life from weeks to years.
- Reduced Connectivity Costs: By replacing long topic strings with 2-byte Topic IDs, the gateway reduces bandwidth consumption, which is critical for users on expensive satellite or NB-IoT data plans.
Benefits for the ThingsBoard Ecosystem
- Hardware Interoperability: This feature opens the ecosystem to a vast range of ultra-lightweight Zigbee and Bluetooth sensors that cannot maintain a standard TCP/IP stack.
- Architectural Scalability: Offloading protocol translation to the Gateway prevents "code bloat" in the broker core, ensuring the system remains lean and high-performance while still supporting legacy and constrained protocols at the edge.
