OneNET AT example

We use OneNET AT commands to quickly get started with OneNET, and let's demonstrate a smart bulb project.

Hardware: NodeMCU development board

App: android:onenetdemo_android_1.0.0_20170321.zip iOS:onenetdemo_ios_03_16.zip

Documentation: onenet_android_user_guide.pdf　onenetdemo_ios_user_guide.pdf

Firmware: ai-thinker_esp8266_dio_onenet_v1.4_20160518.7z

Tools: 开发工具清单 (including serial port tools and download tools)

* Log in to http://open.iot.10086.cn/

* Register a platform account

After logging in to your account, click to enter the developer center:

* Click to create product

* Fill in product parameters

We choose wifi, open protocol, EDP protocol, and named it smart bulb light.

* The creation is complete.

The product ID and APIKey in the above column are two important parameters, which will be used by AT commands.

Here is a demonstration with my project parameters.

Use the USB data cable to connect the NodeMCU development board, the serial port configuration 115200,N,8,1, open the serial port.

Burn OneNET AT firmware ai-thinker_esp8266_dio_onenet_v1.4_20160518.7z

* Connect router

AT+CWMODE=1
OK

AT+CWJAP="TP-LINK_9E20","admin123456"
WIFI DISCONNECT
WIFI CONNECTED
WIFI GOT IP

* Configure OneNET parameters

AT+CIOT? // Query whether the OneNET parameters have been configured
+ERR=-102 // No master_apikey
+ERR=-103 // No device serial number
+ERR=-104 // There is no project ID of the project to which the device belongs

AT+CIOTMKEYA="0sS65LxJsWcPvR8oaGmVTljCxqc=" // Configure the apikey of the bulb project
+OK=0sS65LxJsWcPvR8oaGmVTljCxqc=

AT+CIOTPID="41880" // Configure project ID
+OK=41880

AT+CIOTSN="light-56834" // Configure the serial number (Note: The serial number must be unique, otherwise it will not be registered on OneNET, you can use a random number as the serial number)
+OK=light-56834

AT+CIOTNAME="Light" // Set the name prefix for the device, you will see the device name of Light_xxxxxxxx_xxxxxxxx if the device is created successfully
+OK=Light

AT+CIOT? // Check again whether the parameters have been configured
+OK

* Connect OneNET

AT+CIOTINIT // Connect OneNET, register the device
+OK // Return +OK if the device is registered successfully, otherwise an error will be returned. If an error occurs, return to the previous step to reconfigure the correct project parameters.
                         // Note that the sequence must be unique and cannot be repeated.

AT+CIOTSTART=0 // Connect to OneNET (TCP connection), 0: no encryption.
+OK

AT+CIOTSTATUS // Query the online status of the device: device_down, device_up
+OK=device_up

AT+CIOTQUIT // Disconnect OneNET
+OK

* Send data points

AT+CIOTDAT=5,r,,240,g,,200,b,,80,w,,80,s,,1 // Send 5 data points (r,g,b,w,s), reference AT command format document
+OK

Because OneNet does not open the account system for the time being, we can only log in with apikey.

* Fill in the master_apikey of the project (0sS65LxJsWcPvR8oaGmVTljCxqc=)

* Get device list Click Go To Device List

* controlling device

* Data points sent by the APP to the device

 +IOTCMD=5,r:107 // 5 means 5 characters have been received, and the printed characters are after the comma
 +IOTCMD=5,b:217
 +IOTCMD=4,g:87
 +IOTCMD=3,s:0
 +IOTCMD=3,s:1
