Mqtt.fx connects to Alibaba cloud Internet of things platform

Novice entry level mainly describes the general process and their understanding of learning

Forward thinking ： Old engineer ： Code is not the hardest , The plan is the most difficult . Make clear the plan 、 As long as the code learns it, it will , It will happen sooner or later, right ;

MQTT.fx It is used to debug Alibaba cloud , Just use this configuration , It's the same with SCM configuration , So at the beginning, you don't need to use the board directly. First, use this software to connect Alibaba cloud , Then use the same principle to get it on the board , This chapter focuses on using software to debug Alibaba cloud , SCM provides a general idea

 outline ：
	 Different microcontrollers （srm32 51 NXP...）,				//
	 Different transmission protocols （MQTT HTTPS 4G modbus...）,	//MQTT HTTPS It's all based on TCP/IP Application communication protocol on the Protocol ,modbus It is widely used in industry 
	 Different ECs （ Alibaba cloud   Hua Wei Yun  OneNET( Originator )...）,	// Tencent cloud , Atomic cloud （ The punctual atoms ）
	 They are similar in use , As long as you learn a way to understand the principle, you can draw inferences from one instance .

step ：https://www.processon.com/view/link/6124549ce401fd5228f8f94a password ：5555
Cloud configuration ：（ Here it means STM32 equipment Aliyun server MQTT agreement , The upper configuration is the same ）

It can be concluded that the step is 1. Create products ->1.1 Add equipment 2. New projects ->2.1 New application
1. Create products ：

Create success ：

1.1 Add equipment （ Product selection required , Products must be created first ）

Add success ：

software test （MQTT.fx） Connect ：

Alibaba cloud official website uses MQTT.fx Connect IOT connection steps ：
