Getting Started with the NodeMCU- Access Point and Station (By Akshet Patel)
- 2. What is an Access Point and Station ? When you set the ESP8266 as an access point you create its own Wi-Fi network and nearby Wi-Fi devices (stations) can connect to it (like your smartphone or your computer). When the NodeMCU is in Station mode, it can connect itself to any Hotspot or Wi-Fi network router.
- 4. Some Important Commands: Library: A library is a reusable chunk of code that you may want to include in your programs. These may include message templates, pre-written code and subroutines, values or type specifications. 1. #include <ESP8266WiFi.h> No wifi related commands will work without this library. 2. WiFi.begin("WiFiName", "WiFiPassword"); //Command to connect to a WiFi Network 3. WiFi.status(); //To check if it is connected to a Network or not. WiFi.status() values can be: WL_CONNECTED - connected WL_IDLE_STATUS - trying to connect WL_CONNECT_FAILED - connection failed 4. WiFi.localIP: returns the IP address of the connected network.
- 5. 5. WiFi.scanNetworks(): Scans for available WiFi networks and returns the discovered number. 6. WiFi.softAP(“network name”, “network password”): Creates its own network and generates its own IP Address. 7. WiFi.softAPIP(): Returns the IP address generated by the nodeMCU behaving as an access point. 8. WiFiClient: Creates a client that can connect to to a specified internet IP address. 9. server.available(): Gets a client that is connected to the server and has data available for reading.
