These cloud servers provide a large number of platform software basic component modules and API service, which makes the development of platform software efficient and fast. The MQTT communication protocol has become the standard for IOT and smart devices. Using the MQTT protocol is easy to build a communication service with IOT device on the server, whether it is Amazon AWS or Google, Microsoft, Alibaba, Tencent or Huawei clound server have provided MQTT access kits and services. In order to meet the development needs of customers' software platforms, we released our first version MQTT protocol for the T-Box control system.
