@ohos.wifiManager (WLAN) (System API)

The WLAN module provides basic wireless local area network (WLAN) functions, peer-to-peer (P2P) functions, and WLAN message notification services. It allows applications to communicate with devices over WLAN.

NOTE The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version. This topic describes only the system APIs provided by the module. For details about its public APIs, see @ohos.wifiManager (WLAN).
