从 Android 访问信标帧信息
是否可以读取接入点在定期发送的信标帧中提供的信息? 或者至少有可能监视信标帧吗?
Is it possible to read the information provided by Access Points in their periodically sent beacon frames?
Or is it possible to at least monitor beacon frames at all?

当然可以,不然为什么要先发呢?
这正是 WiFi 驱动程序的作用。如果您希望在应用程序中包含此信息,则必须将驱动程序配置为嗅探器模式(如果支持)并安装某种嗅探应用程序,例如
wireshark
。Of course it's possible, otherwise why would it be sent in the first place?..
That's exactly what WiFi driver does. If you want to have this info in your application, you must configure your driver to sniffer mode (if supported) and install some kind of sniffing application such as
wireshark
.
