Mtk WIFI常用調試指令

原文：http://blog.csdn.net/gamelife_lch/article/details/21520075

在手機開發之初，我們很多時候要在lcm和tp還沒有正常工作的時候就需要同步的進行wifi子產品功能的開發，是以了解常用的指令會有助于我們快速的開發我們的手機，以下就是列出的常用指令供大家借鑒運用：

 1、開啟或關閉wifi:

首先adb shell進入手機調試

[email protected]:/ # echo 0 > dev/wmtWifi         關閉wifi                                 

[email protected]:/ # echo 1 > dev/wmtWifi         開啟wifi

2、檢視wifi工作狀态指令netcfg

[email protected]:/ # 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   //說明wifi已經正常開啟

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、對wifi進行掃描連接配接等操作由如下兩個操作

首先進入System/bin目錄

[email protected]:/ # cd system/bin/                                                

[email protected]:/system/bin # ./wpa_supplicant -Dnl80211 -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf &   //将wpa_supplicant調起來，可用ps指令檢視是否起來

(如果配置檔案不在上述目錄，請使用這個路徑：/system/etc/wifi/wpa_supplicant.conf)

(上述指令執行後會阻塞在指令行，如果要執行其他指令，請另開一個指令行界面)

(判斷wifi或者supplicant是否運作起來，可以通過ps指令檢視是否有tx_thread和./wpa_supplicant程序)

運作wpa_cli:

如果上面指令不成功，請執行：wpa_cli  -p  /data/misc/wpa_supplicant

接下來我們看一下測試結果：

[email protected]:/ # cd system/bin/                                                

[email protected]:/system/bin # ./wpa_supplicant -Dnl80211 -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf &
