1pcs ESP8266 Serial To WIFI Module ESP-12S Industrial Grade Wireless ESP-12 ESP 8266 IOT | Электроника

Convenient development environment, free virtual machine and familiar with the Linux system, directly in the Windows environment to develop, save development time, ahead of the market to seize; Add AT + CLDSTART, start the cloud connection, the default parameters for the security can Ai-Cloud cloud platform, the implementation of this directive, the system will automatically maintain the cloud connection and heartbeat package, and disconnected. The system handles all protocol layers. AT + CLDSTOP Stop the cloud connection. Release all cloud-related system resources. AT + CLDSEND = Send data to the cloud. Parameter is the data length, the implementation of this command, the system will return ">", then you can send a certain length of data. Data reception When the cloud data comes, you will receive + CLD, : Len is the data length, data is the specific data. Smart connection AT + CWMODE = 1 AT + SMARTSTART = 1 This is done using ESP_TOUCH technology. (1.2.0 version can be directly after the command "AT + CWSTARTSMART", do not need to set the parameters, SmartConfig type can be automatically obtained, no need to set. Added to join the cloud family group command AT + LANSTART, can be easily joined the cloud family group, with the APP side to control; Added exit cloud family group instruction AT + CLDUNBIND, module cloud control transfer? A command to exit the cloud family group, no longer bound by binding; Add WPS function, AT + CWWPSSTART direct open WPS, more convenient configuration WiFi connection; Add AT command AT + CIOWRITE can set the IO state, an instruction can control the different high and low IO level; Added AT command AT + CIOREAD can read IO status, a command can read the status of different IO; Add AT command AT + CSYSHEAP at any time to view the remaining RAM size, the remaining space readily grasp; Added AT command AT + CIOADC can read ADC, input voltage range of 0 ~ 1V.

   Advantages of this module:
