### Wi-Fi Scanning
|
||||
|
||||
Provisioning manager also supports providing real-time Wi-Fi scan results (performed on the device) during provisioning. This allows the client side applications to choose the AP for which the device Wi-Fi station is to be configured. Various information about the visible APs is available, like signal strength (RSSI) and security type, etc. Also, the manager now provides capabilities information which can be used by client applications to determine the security type and availability of specific features (like `wifi_scan`).
