小米4 hostapd配置热点

Posted 2022-12-21 osnet

hostapd

adb shell：
hostapd -i wlan0 /data/misc/wifi/hostapd.conf

配置ip地址
ifconfig wlan0 192.168.2.15 up

hw_mode表示采用哪种协议模式，其中a = IEEE 802.11a支持5.0Ghz，默认g = IEEE 802.11g 2.4G频段
#Operation mode (a = IEEE 802.11a, b = IEEE 802.11b, g = IEEE 802.11g,
#n = IEEE 802.11n, g_only = IEEE 802.11g_only, n_only = IEEE 802.11n_only,
#Default: IEEE 802.11n
hw_mode=a

netd

ndc命令可以配置热点模式，
netd中根据channel个数决定采用IEEE 802.11a还是IEEE 802.11g
std::string wbuf(StringPrintf(“interface=%s\\n”
“driver=nl80211\\n”
“ctrl_interface=/data/misc/wifi/hostapd\\n”
“ssid=%s\\n”
“channel=%d\\n”
“ieee80211n=1\\n”
“hw_mode=%c\\n”
“ignore_broadcast_ssid=%d\\n”
“wowlan_triggers=any\\n”,
argv[2], argv[3], channel, (channel <= 14) ? ‘g’ : ‘a’, hidden));
