Using an Async web server has many benefits as discussed on the official GitHub page of this library: In this tutorial, we will use the ESPAsyncWebServer library to build an Asynchronous Web Server with ESP8266 NodeMCU and Arduino IDE. In other words, in an asynchronous server, client HTTP requests do not block each other and get executed concurrently. It has a worker process that accepts HTTP requests from all clients and processes client requests by using event-driven efficient loops. On the contrary, Asynchronous servers do not create a separate thread for each client request. But it may induce blocking problems when a server is waiting for the process to release the resources. In the case of traditional thread based servers, there is a dedicated separate thread for each client to serve that particular client.
This function has two parameters: a network SSID and password. To connect your ESP8266 to the local WiFi network, call nnect(). Serial.println("Unable to communicate with the ESP8266 :(") Įsp8266.begin() must be called before any other ESP8266 function. Serial.println("ESP8266 ready to go!") // Communication and setup successful
If (esp8266.begin()) // Initialize the ESP8266 and check it's return status This function will return either true or false, indicating if communication was successful with the ESP8266. In your setup(), to initialize the ESP8266 and make sure it's functioning, call esp8266.begin(). #include // Include the ESP8266 AT library
#Esp8266 serial library software
#include // Include software serial library, ESP8266 library dependency You'll need to include two libraries at the top of any ESP8266-using Arduino sketch: and : language:c For more documentation check out the library's GitHub repository. This section will document some of the more commonly-used functions. The example from the previous section - and the others included with the library - should go a long way towards demonstrating the usage of the SparkFun ESP8266 AT library.
