Detailed Description

A component thet implements web-based configuration portal accessible from local network.

The portal can be used to upload OTA update, both in access point and station mode. There's also web-based terminal which can be used to debug the device and examine realitme application logs.

In case of confiugrator application, please don't add this component directly and use ksWifiConfigurator instead. In case of "normal application", you have to add the component manually if you want to use it.
