MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. Dusun gateway supports MQTT protocol to connect to cloud platform.

The DSGW-040 is a gateway product used in the smart home, intelligent security industry, pension services. It’s a central device, supports LTE-M1 (EMTC), Wi-Fi, zigbee3.0, Bluetooth and Z-WAVE wireless protocol.

The DSGW-040 gateway makes it easier for users to connect the network through LTE-M1, Wi-Fi and Ethernet. In addition, smart sensors can be connected through zigbee3.0, Bluetooth and Z-wave.  

An IoT gateway aggregates sensor data, translates between sensor protocols, processes sensor data before sending it onward and more. The Dusun gateways supports most connectivity protocols including BLE（4.x/5.0/Mesh）, ZigBee 1.2/3.0, Z-Wave, TCP/UDP.

Gateways communicate with sensors/devices over varying connectivity types. Dusun smart gateways are Linux based and programmable. Then Dusun’s gateway can use any standard protocols to transfer data into Cloud.

Many IoT smart devices including Dusun’s smart home sensors can be connected and operated through these Apps. This guide will show how to connect Dusun’s Gateway and smart devices.
