/**

|
* Manages connection and provisioning of WiFI
|
||
|
|
*
|
||
|
|
* Starts in state AP_PROVISIONING, where device is an access point without password.
|
||
|
|
* Device should not work normally in this mode, only API is served to set password.
|
||
|
|
* Two options:
|
||
|
|
* - connect to existing WiFi (station mode), via setStaCredentials
|
||
|
|
* - create secured access point, via setApCredentials
|
||
|
|
*
|
||
|
|
* When operating in access point mode, the device IP is 192.168.42.1
|
||
|
|
*
|
||
|
|
* call wifiWatchdog regularly to reconnect in station mode if connection was lost
