WiFiServer::WiFiServer |
Constructs a WiFiServer object and creates a server that listens for incoming connections on the specified port |
Public Methods |
|
WiFiServer::available |
Gets a client that is connected to the server and has data available for reading. The connection persists when the returned client object goes out of scope; you can close it by calling the client.stop() |
WiFiServer::begin |
Tells the server to begin listening for incoming connections |
WiFiServer::write |
Write data to all the clients connected to a server |
