android - 在Wi-Fi 热点模式下，如何获取周围的打开wifi 的终端设备列表

Question

stackoverflow 上看到一个 Android:Hotspot is not detecting all ...

Android 手机可以通过读取/proc/net/arp 文件获取设备列表，但是这些设备是需要成功连上wifi 的。Ubuntu 上的hostapd 也可以。看系统日志，终端设备的MAC 地址是终端设备主动连接之后， dnsmasq 进程获得的。

有没有办法， 获取不一定会连上热点的周围所有设备列表？就是说能否让AP 主动扫描设备？

如果Android 上直接有办法更好，毕竟不需要电源，使用方便。如果是其它平台，PC或者修改路由器的固件(如OpenWrt, Tomato)达到目标的办法或者思路， 也非常欢迎。

Answer 1

Solved, as long as there is network communication, wireshark can hear the data, and the MAC addresses of both parties are visible.

On the Android platform, there is also a ported version of wireshark, Shark for Root
