Before the change, with only the GET_WIFI_INFO permission, the application can obtain the BSSID of the hotspot connected by the user, and further determines the location of the user. This poses security risks. 12 13**Change Impact** 14 15This change is a non-compatible change. 16 17Before the change: 18 19With the GET_WIFI_INFO permission only, the application can obtain the BSSID of the hotspot connected by the user. 20 21After the change: 22 23To obtain the BSSID of the connected hotspot, the application must have the GET_WIFI_INFO and GET_WIFI_PEERS_MAC permissions. If the application does not have the GET_WIFI_PEERS_MAC permission, the returned BSSID is empty. 24 25**Start API Level** 26 27API 12 28 29**Change Since** 30 31OpenHarmony 5.0.0.37 32 33**Key API/Component Changes** 34 35getLinkedInfo/wifi module 36 37**Adaptation Guide** 38 39No adaptation is required.
