/*
|
|
This example demonstrates how to use WPS.
|
|
It supports two modes, which can be selected in menuconfig.
|
|
|
|
WPS_TYPE_PBC:
|
|
Start ESP32 and it will enter WPS PBC mode. Then push WPS button on the router.
|
|
ESP32 will receive SSID and password, and connect to the router.
|
|
|
|
WPS_TYPE_PIN:
|
|
Start ESP32, you'll see an eight-digit PIN number in log output.
|
|
Enter the PIN code on the router and then the ESP32 will get connected to router.
