Built-in cloud services is that you can use three commands into the global remote control function.
Use Shun Technology official firmware can be achieved:
1) Convenient development environment, a virtual machine installed free and familiar with Linux systems, developed directly in the Windows environment, saving development time, advance to seize the market;
2) New AT + CLDSTART, start Cloud connection, the default parameters can Shun Ai-Cloud cloud platform, after executing the entry instruction, the system will automatically maintain the cloud connection heartbeat packet, and reconnection. The system handles all protocol layers.
3) AT + CLDSTOP stop the cloud connection. Releases any system resources associated with the cloud.
4) AT + CLDSEND = <len> to send data to the cloud.
Argument is the data length, after executing this command, the system returns a ">", then you can send a certain length of data.
5) Data received
Cloud data received when + CLD, <len>: <data>
len is the length of the data, data is specific data.
6) intelligent connection
AT + CWMODE = 1
AT + SMARTSTART = 1
This time using ESP_TOUCH technical configuration.
(Version 1.2.0 can be used directly after the command "AT + CWSTARTSMART", you do not need to set the parameters, SmartConfig types can automatically, without setting.
7) added new cloud family group instruction AT + LANSTART, can be easily added to the cloud family group to APP end connection control;
8) new set of instructions to exit the cloud family AT + CLDUNBIND, module Drive Control Transfer? An instruction to exit the cloud family group, no longer bound by the shackles;
9) New WPS function, AT + CWWPSSTART directly open the WPS, more convenient to configure WiFi connection;
10) Add the AT command AT + CIOWRITE can set the IO state, an instruction to control the high and low of different IO;
11) Add the AT command AT + CIOREAD read IO state, an instruction to read different IO state;
12) Add the AT command AT + CSYSHEAP can always see the remaining RAM size, the remaining space is readily grasp;
13) Add the AT command AT + CIOADC read ADC, the input voltage range of 0 ~ 1V;
Shun cloud can be used in two ways:
Cloud service code can run 1 Shun Shun on the host can be free of charge to you.
Cloud service code runs 2 Shun can on your own host.
For the module side:
AT with only a call to join the cloud server command, and then directly send and receive data remotely. very simple
If you do not want to use AT commands to develop, then we can use our EMC can be embedded in the AI-CLOUD 8266 SDK to develop.
For mobile phone APP side:
We can offer based Shun Andrews and IOS source code that demonstrates the entire common IOT architecture. Such as WIFI socket, WIFI lamps, WIFI fan, WIFI alarms.
This module Advantages:
1) low price, basically only to earn a small profit, we hope that this will drive more rapid development of the Internetof Things.
2) do the smallest around 11 * 10 mm, size of a fingernail. It is easily embedded into any product
3) Powerful internal protocol run LWIP
4) supports three modes: AP, STA, AP + STA coexistence mode
5) perfect simple and efficient AT commands, allows you to develop easier.
