Preface  

        Anxinco technology released a while ago NB-IoT Module ——EC Series modules . It also supports TCP、HTTP、MQTT And LwM2M agreement . especially LwM2M agreement , This is a WiFi What the module does not have .OneNET There is also a separate product creation of this Agreement on the platform , But this Agreement does not apply to WiFi Access to .

        So here's the problem , If you want to use WiFi and EC Family modules also support access OneNet How to achieve ,OneNET In the old version of the platform , There are multiple protocol access ways to create products . For example, use MQTT Access Agreement , So you can use it WiFi Class direct connected devices and NB Class devices are connected at the same time .

        This chapter will teach you how to multi protocol access OneNET Open platform of Internet of things .

One 、OneNET Creation of multi protocol access

 1. Enter into OneNET Home page ：OneNET - China Mobile Internet of things open platform , And go to the console ：

  2. Switch to the old console ：OneNET - Old version of IOT console

 

 3. Create multi protocol access products

  4. Create device

Two 、EC-01 Access preparation

1. Platform connection elements

        EC-01 Three elements are needed to access the created device ：

• product ID, This article tests ID：485938
• equipment ID, This article tests ID：877672367
• Device authentication information , Equipment authentication in this paper ：ec01test

product ID You can check it in the product overview ：

equipment ID And authentication information can be found in ： device details . see

2.EC-01 Development board ready

        Anxinko's EC There are three development boards in the series , In line with the consistent stingy principle of the sufficient author , We choose EC-01F-Kit This development board ：

The total required hardware equipment is ：

• EC-01F-Kit Development board
• Mobile IOT network card 300M A year
• NB The antenna

On some treasure , The whole set is for sale , But here's the thing ：

After the IOT network card is connected to the development board , You can't load other development boards , Otherwise, it will cause locking .

  3、 ... and 、 Instruction access

1. First EC-01F To complete network access ：

        Only after successful network access , To access OneNET, The instruction flow related to network access is as follows ：

 2. Access OneNET 

        After successful network access , You can use AT Instruction access OneNET, The specific process is as follows ：

• step 1： Use mqtt conf Command configuration cloud The type is OneNet 
• step 2： Use mqtt open and mqtt connect establish mqtt Connect
• step 3： Use mqtt sub subscribe topic
• step 4： Use mqtt pub send data
• step 5： When mqtt server When sending data ,mqtt receive The command will be automatically received , And ”+ECMTRECV: XXX” Of Format , Print out
• step 6： Use mqtt disconnect Delete mqtt Connect

  The specific instructions are as follows ：

  // step 1：
  AT+ECMTCFG ="cloud",0,1,3
  // step 2：
  AT+ECMTOPEN=0,"183.230.40.39",6002
  // step 3：AT+ECMTCONN=0," equipment ID"," product ID"," Authentication information "
  AT+ECMTCONN=0,"877672367","485938","eec01test"
  // subscribe Topic  Use it to receive the platform carefully 
  AT+ECMTSUB=0,1,"test",2
  // Publishing data streams 
  AT+ECMTPUB=0,0,0,0,"$dp","{"ec_data":36,"es_data_str":"hello OneNET"}"
  // disconnect 
  AT+ECMTDISC=0

  The normal process is as follows ：

  Four 、 Data interaction

 1. Data upload

        Data upload uses release instructions ：AT+ECMTPUB

        The upload format is generally json Format , Instruction example ：

AT+ECMTPUB=0,0,0,0,"$dp","{"ec_data":36,"es_data_str":"hello OneNET"}"

In this directive , Uploaded numerical data named ："ec_data", The value is ：36;

The string type data name is ："es_data_str", The content of the string is ："hello OneNET"

The platform displays the result as ：

 2. Data reception

        be familiar with MQTT Everyone who agrees knows , Want to receive data , All need to subscribe , Subscription requires Topic, however OneNET The products of multi protocol access are different , It has no Topic, So we can subscribe Topic, The instructions are as follows ：

AT+ECMTSUB=0,1,"test",1

Directive ：“test”, Namely Topic, Specific parameters can be found in the official website of Anxin docs see ：https://docs.ai-thinker.com/_media/nb-iot/nb-ioAT Instruction set v1.0.pdf

OneNET The platform issues instructions ：

        Article OneNET Platform equipment is test equipment , Post article , I will delete relevant devices , Please create your own products and equipment for testing ,AT The parameters of the instruction should be your own related parameters .
