我是靠谱客的博主追寻白开水，最近开发中收集的这篇文章主要介绍Mtk WIFI常用调试命令，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

在手机开发之初，我们很多时候要在lcm和tp还没有正常工作的时候就需要同步的进行wifi模块功能的开发，所以了解常用的命令会有助于我们快速的开发我们的手机，以下就是列出的常用命令供大家借鉴运用：

1、开启或关闭wifi:

首先adb shell进入手机调试

root@Eclipse:/ # echo 0 > dev/wmtWifi 关闭wifi
root@Eclipse:/ # echo 1 > dev/wmtWifi 开启wifi

2、查看wifi工作状态命令netcfg

root@Eclipse:/ # netcfg
rndis0 UP 192.168.42.129/24 0x00001043 b6:49:11:24:f4:74
ip6tnl0 DOWN 0.0.0.0/0 0x00000080 00:00:00:00:00:00
sit0 DOWN 0.0.0.0/0 0x00000080 00:00:00:00:00:00
ifb1 DOWN 0.0.0.0/0 0x00000082 f6:c2:f5:3b:86:5f
ifb0 DOWN 0.0.0.0/0 0x00000082 62:76:1d:10:b5:1f
lo UP 127.0.0.1/8 0x00000049 00:00:00:00:00:00
wlan0 UP 172.26.61.36/24 0x00001043 78:f5:fd:64:7b:fa //说明wifi已经正常开启
tunl0 DOWN 0.0.0.0/0 0x00000080 00:00:00:00:00:00
ccmni2 DOWN 0.0.0.0/0 0x00000080 96:25:62:66:5b:91
ccmni1 DOWN 0.0.0.0/0 0x00000080 16:d9:3b:66:9e:69
ccmni0 DOWN 0.0.0.0/0 0x00000080 62:eb:82:7d:ec:b3

3、对wifi进行扫描连接等操作由如下两个操作

首先进入System/bin目录

root@Eclipse:/ # cd system/bin/
root@Eclipse:/system/bin # ./wpa_supplicant -Dnl80211 -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf & //将wpa_supplicant调起来，可用ps命令查看是否起来

(如果配置文件不在上述目录，请使用这个路径：/system/etc/wifi/wpa_supplicant.conf)
(上述命令执行后会阻塞在命令行，如果要执行其他命令，请另开一个命令行界面)
(判断wifi或者supplicant是否运行起来，可以通过ps命令查看是否有tx_thread和./wpa_supplicant进程)
运行wpa_cli:

如果上面命令不成功，请执行：wpa_cli -p /data/misc/wpa_supplicant

接下来我们看一下测试结果：

root@Eclipse:/ # cd system/bin/
root@Eclipse:/system/bin # ./wpa_supplicant -Dnl80211 -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf &
[1] 22855
