If push button is detected * to be pressed at boot time, the thing will use the initial * password for accepting connections in Access Point mode. This * is usefull e.g. when custom password was lost. * (See previous examples for more details!) * * Hardware setup for this example: * - An LED is attached to LED_BUILTIN pin with setup On=LOW. * This is hopefully already attached by default. * - A push button is attached to pin D2, the other leg of the * button should be attached to GND. */ #include // -- Initial name of the Thing.
