Esp8266 arduino web server example1/23/2024 The function will wait while this is not the connection status and, when identifying it, it will look for the IP address it received on the network. In this project, we are not handling connection failures, so we are only interested in the WL_CONNECTED return. WL_DISCONNECTED: assigned when disconnected from a network.WL_CONNECTION_LOST: assigned when the connection is lost.WL_CONNECT_FAILED: assigned when the connection fails for all the attempts.WL_SCAN_COMPLETED: assigned when the scan networks is completed.WL_NO_SSID_AVAIL: assigned when no SSID are available.WL_IDLE_STATUS: it is a temporary status assigned when WiFi.begin() is called and remains active until the number of attempts expires (resulting in WL_CONNECT_FAILED) or a connection is established (resulting in WL_CONNECTED).WL_NO_SHIELD: assigned when no WiFi shield is present.WL_CONNECTED: assigned when connected to a WiFi network.The WiFi.status() function can return the following values: With Wifi.begin(), ESP8266 will search the network informed in the ssid variable and send a connection request, informing the password (just like what a cell phone would do). The wifiConnect() function will send a connection request and wait for it to be approved. The connection could be executed directly in the setup function, but we will create a standalone function to make the code more organized and so that it can be reused if you want to create a reconnect function.We'll start by creating a variable to store the network name and another one for the password. Now let's connect the ESP8266 to your WIFI network.Remember to remove the data inside the loop function when you finish the test. With this code, the NodeMCU module LED, we expect to change state every 3 seconds.With these inclusions, we will have this code:. To test the function, you can include it in the loop as follows:
