Where WIFI becomes initialized?

[pom]

Hello,

I'm using ESP12 with Arduino IDE.

When init() is called WIFI is already active.

Is WIFI activated on RTOS level? Or on Arduino code level?

Can anyone tell me where WIFI becomes activate?


Thanks,
Peter

I am not sure about the Arduino interface as it is not officially supported via any documentation by us. But in all the SDKs which Arduino for ESP8266 can use, the init() function is executed when the radio has already been initialized using last-known configurations (stored in flash). If you make any changes to WiFi settings in the init() function, they are executed when you exit init().
