/**
|
|
* Example: Status and Reset
|
|
* Description:
|
|
* This example is very similar to the "mininal" example.
|
|
* But here we provide a status indicator LED, to get feedback
|
|
* of the thing state.
|
|
* Further more we set up a push button. 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.
