We have created many functions for ESP8266.

• allows to connect to a wifi
• Execute an action
• send a float data on our iot platform (https://iot.youpilab.com); return 1 in case of success and 0 in case of failure
• send a String data on our iot platform (https://iot.youpilab.com); return 1 in case of success and 0 in case of failure
• send a int data on our iot platform (https://iot.youpilab.com); return 1 in case of success and 0 in case of failure
• send a boolean data on our iot platform (https://iot.youpilab.com); return 1 in case of success and 0 in case of failure
• Get information from the created Thing on our iot platform
• You can execute a task you have written in the terminal thing using this methode
• count the number of data received by our iot platform
• send feed back

All these functions have been properly commented to your comprehension
