An IoT gateway aggregates sensor data, translates between sensor protocols, processes sensor data before sending it onward and more.
The Dusun IoT gateways support most connectivity protocols including BLE（4.x/5.0/Mesh）, ZigBee 1.2/3.0, Z-Wave, TCP/UDP, etc. Users can connect the gateway with various BLE devices.
As the Dusun gateway is running based on the Linux system, how to implement an application over Bluez stack to ‘talk’ with BLE devices
Dusun’s gateways run Linux OpenWrt system. UBUS is a message bus in OpenWrt. Its main function is to realize information exchange between different applications.
