1、无密码和有密码的scanresults 里信息是啥样的？
主要区别就是里面的capabilities
有密码的：
07-26 05:42:01.153 3355 3355 I WifiBroadcastReceiver: scanResult==== : SSID: Redmi_697B, BSSID: a4:39:b3:70:8c:20, capabilities: [WPA2-PSK-CCMP][RSN-PSK-CCMP][ESS][WPS], level: -20, frequency: 2437, timestamp: 2568823930, distance: ?(cm), distanceSd: ?(cm), passpoint: no, ChannelBandwidth: 0, centerFreq0: 2437, centerFreq1: 0, standard: 11n, 80211mcResponder: is not supported, Radio Chain Infos: [RadioChainInfo: id=0, level=-22, RadioChainInfo: id=1, level=-19]
无密码的：
