一、前言

Android系统调试是，如果没有系统原生设置应用又需要调试验证WiFi功能时，

可以使用一些指令来验证调试WiFi相关功能，

最常用的就是 svc wifi enable/disable，或者使用iv dev来验证，

但对于AP功能就没办法验证了，并且可调试功能比较少，

其实Android系统自带有组很强大的shell指令集，

这里记录下平时使用的cmd wifi 相关指令。

系统初期开发或者定位一下wifi、热点问题会比较有用。

本文不仅详细介绍cmd wifi相关用法，并且后续有介绍系统Java代码中具体控制位置，

如果有特殊需求可以对命令进行扩展定制。

目前网上还没有这么全面介绍的文章，有wifi调试需求的可以先收藏后续慢慢查看。

二、adb shell cmd wifi 主要命令

### 1、adb shell cmd wifi -h

查看WiFi所有指令以及参数

命令具体信息太多，最后展示。

串口查看命令具体参数技巧，grep 某个关键字：

console:/ # cmd wifi -h | grep   connect-network                               
  connect-network <ssid> open|owe|wpa2|wpa3|wep [<passphrase>] [-x] [-m] [-d] [-b <bssid>] [-r auto|none|persistent|non_persistent]
console:/ #

下面很多命令返回的结果是使用串口工具展示的，串口命令是不需要adb 连接的。

2、打开关闭WLAN

adb shell cmd wifi set-wifi-enabled enabled

adb shell cmd wifi set-wifi-enabled disabled

3、扫描WiFi 和查看扫描列表

adb shell cmd wifi start-scan             //扫描

adb shell cmd wifi list-scan-results    //查看扫描结果

cmd wifi list-scan-results 命令扫描到的信息：

console:/ # 
console:/ # cmd wifi list-scan-results  
    BSSID              Frequency      RSSI           Age(sec)     SSID   Flags
  48:5f:08:ed:f7:f1       5200        -68             10.148    synwcs_5G                         [WPA2-PSK-CCMP][RSN-PSK-CCMP][WPA-PSK-CCMP][ESS]
  34:f7:16:92:87:6c       2442        -38             10.148    syrj                              [WPA-PSK-CCMP][WPA2-PSK-CCMP][RSN-PSK-CCMP][ESS]
  de:00:1a:bc:b3:4a       2422        -57             10.148    IFLYHub_86_7849                   [WPA2-PSK-CCMP][RSN-PSK-CCMP][ESS]
  80:ea:07:28:ef:1c       5240        -96             10.148    HorionRj_5G                       [WPA-PSK-CCMP+TKIP][WPA2-PSK-CCMP+TKIP][RSN-PSK-CCMP+TKIP][ESS]
  48:5f:08:45:a6:c1       5805        -53             10.148    SYEBSW-5G                         [WPA-PSK-CCMP][WPA2-PSK-CCMP][RSN-PSK-CCMP][ESS]
  f4:84:8d:24:19:35       5785        -77             10.148    synwcs-m_5G                       [WPA-PSK-CCMP][WPA2-PSK-CCMP][RSN-PSK-CCMP][ESS]

console:/ #

扫描列表中信息含义：

BSSID     ：MAC地址
Frequency ：信号频段，5G：5160到5865，2.4G：2401~2483MHz
RSSI      ：wifi信号强度，RSSI >=-55为满格信号,level为4，每个level之间的Rssi的跳变为15
Age(sec)  ：响应时间？
SSID      ：wifi名称
Flags     ：加密格式，包含加密相关字符

4、连接WiFi

adb shell cmd wifi connect-network wifiName wpa2 12345678

//wifiName 连接WiFi名称

//wpa2 加密方式,如果没有密码写 open ，最后的密码不用写

//12345678 密码

如果没有密码，连接xm名称的wifi：

cmd wifi connect-network xm open

5、查看WiFi状态

adb shell cmd wifi status

(1) wifi 正常连接下的信息：

C:\Users\As11040>adb shell cmd wifi status
Wifi is enabled //（1）查看到Wifi的开关状态
Wifi scanning is only available when wifi is enabled //（2）扫描状态
==== Primary ClientModeManager instance ====
Wifi is connected to "xm5G" //（3）wifi连接的名称，下面是详细信息
WifiInfo: SSID: "xm5G", BSSID: 8c:53:c3:53:c6:59, MAC: c0:f5:35:4f:a3:e0, IP: /192.168.31.17, Security type: 0, Supplicant state: COMPLETED, Wi-Fi standard: 5, RSSI: -46, Link speed: 702Mbps, Tx Link speed: 702Mbps, Max Supported Tx Link speed: 866Mbps, Rx Link speed: 780Mbps, Max Supported Rx Link speed: 866Mbps, Frequency: 5785MHz, Net ID: 2, Metered hint: false, score: 60, isUsable: true, CarrierMerged: false, SubscriptionId: -1, IsPrimary: 1, Trusted: true, Restricted: false, Ephemeral: false, OEM paid: false, OEM private: false, OSU AP: false, FQDN: <none>, Provider friendly name: <none>, Requesting package name: <none>"xm5G"openMLO Information: , Is TID-To-Link negotiation supported by the AP: false, AP MLD Address: <none>, AP MLO Link Id: <none>, AP MLO Affiliated links: <none>

lostTxPacketsPerSecond: 0.0
successfulRxPackets: 173
successfulRxPacketsPerSecond: 2.4364789031543634

C:\Users\As11040>

(2)串口查看wifi关闭情况的信息：

console:/ # cmd wifi status                                                    
Wifi is disabled
Wifi scanning is only available when wifi is enabled
console:/ #

(3)串口查看wifi开启，但是未连接wifi情况的信息：

console:/ # cmd wifi status                                                    
Wifi is enabled
Wifi scanning is only available when wifi is enabled
==== ClientModeManager instance: ConcreteClientModeManager{id=2374293 iface=wlan0 role=ROLE_CLIENT_PRIMARY} ====
Wifi is not connected
console:/ #

6、查看已保存或者连接的WiFi列表

Unknown command: list-network //未连接wifi前的情况
255|console:/ # cmd wifi list-networks                                         
No networks
console:/ # 

console:/ # cmd wifi list-networks //连接wifi后的打印   
Network Id      SSID                         Security type
0            xm5G                             open
0            xm5G                             owe^
1            syrj                             wpa2-psk
1            syrj                             wpa3-sae^
console:/ # 
console:/ #

上面可以看到每连接一个wifi都会有重复多一个，另外一个信息是不准确的，这个不影响。

7、打开关闭热点

（1）打开热点

adb shell cmd wifi start-softap ap_ssidxx wpa2 12345678 -b 5

// ap_ssidxx 热点名称

// wpa2 加密方式

//12345678 密码

//-b 5 5G频段

实际运行运行中，运行上面代码，会有点小问题：

热点是开启了，也可以被搜到和连接上；

但是打开Setings应用发现，热点名称，密码，加密类型等信息并没有修改，重启后也是无效的；

所以说这个方法开启热点只能单次有效。

（2）关闭热点

adb shell cmd wifi stop-softap

关闭是没啥问题的。

上面标记了15个可能会用到的场景，其他的场景看不懂，也没怎么用过，有兴趣的可以自己看看。

整个信息太多了，有时候不好找。

可以在adb shell 或者设备串口中使用 grep 过滤关键字查看相关信息：

cmd wifi -h | grep xxx关键字

2、 adb shell cmd wifi 命令在系统中的具体代码

Android cmd wifi 控制和查询wifi命令的控制代码都在 WifiShellCommand.java 里面。

WifiShellCommand.java 代码位置：

Android13 或者更新版本的 WifiShellCommand.java 的具体位置：
package\modules\Wifi\service\java\com\android\server\wifi\WifiShellCommand.java
Android11 或者更旧版本的 WifiShellCommand.java 的具体位置：
frameworks\opt\net\wifi\service\java\com\android\server\wifi\WifiShellCommand.java

关键代码如下：

public class WifiShellCommand extends BasicShellCommandHandler {
    @VisibleForTesting
    public static String SHELL_PACKAGE_NAME = "com.android.shell";

    // These don't require root access.
    // However, these do perform permission checks in the corresponding WifiService methods.

                        pw.println("Network Id      SSID                         Security type");
                        for (WifiConfiguration network : networks.getList()) {
                            String securityType = network.getSecurityParamsList().stream()
                                    .map(p -> WifiConfiguration.getSecurityTypeName(
                                                    p.getSecurityType())
                                            + (p.isAddedByAutoUpgrade() ? "^" : ""))
                                    .collect(Collectors.joining("/"));
                            pw.println(String.format("%-12d %-32s %-4s",
                                    network.networkId, WifiInfo.sanitizeSsid(network.SSID),
                                    securityType));
                        }
                    }
                    return 0;
                case ...
            }
        }
    }
    
}

上面只展示了set-wifi-enabled 和 list-networks 命令相关代码，

其他的也是类似的调用WifiService 相关api实现具体功能，部分接口是有用print打印返回的数据。

代码大概有两千多行,有兴趣的可以看看源码：

3、svc控制 wifi、热点、蓝牙命令

svc 主要命令：

adb shell svc power|wifi|bluetooth|usb|nfc

从上面介绍可以知道，其实只要记住 svc，那么就是提示其他相关命令，然后再输入功能命令，就会显示具体参数介绍。

svc 功能只能对某个模块开关等基础功能。

4、iw dev命令

（1）iw dev 示例

iw dev 命令比较特殊，这个命令是直接对节点数据进行查询和设置的，不需要经过WifiService那些Java逻辑。

console:/ # iw dev //查看无线设备信息,和相关节点                                                           
phy#0
        Unnamed/non-netdev interface
                wdev 0x4
                addr c2:f5:35:4f:a3:e0
                type P2P-device
                txpower 31.00 dBm
        Interface wlan1 //热点 节点
                ifindex 17
                wdev 0x2
                addr d2:4e:71:f2:ce:56
                ssid AndroidAP_1026 //热点名称
                type AP
                channel 157 (5785 MHz), width: 80 MHz, center1: 5775 MHz
                txpower 31.00 dBm
        Interface wlan0 //wifi节点
                ifindex 16
                wdev 0x1
                addr c0:f5:35:4f:a3:e0
                ssid xm5G //wifi已连接的名称
                type managed
                channel 157 (5785 MHz), width: 80 MHz, center1: 5775 MHz
                txpower 31.00 dBm
console:/ # sched_stop

这个命令我也不熟悉，是最近几天通过驱动底层开发人员一起调试设备了解到的命令。

（2）通过wifi节点搜索wifi列表

比如搜索wifi列表, iw wlan0 scan | grep SSID：

console:/ # iw wlan0 scan | grep SSID
        SSID: 
        SSID: syrj_5G
                 * SSID List
        SSID: B-LINK-5G_EE7180
        SSID: xm5G
        SSID: ktceb-vpn-5G
        SSID: VPN_5G
        SSID: SYEBSW-5G
        SSID: syrj
                 * SSID List
        SSID: ktceb-vpn-2.4G
        SSID: 
        SSID: SYEBSW-2.4G
console:/ #

如果没有grep SSID会看到很多打印，比如每个wifi的加密情况和其他配置信息。

实际开发调试中系统有出现过上层接口无法打开wifi的情况（原因：上层调用IWifi接口卡死），

但是强制up打开 wlan0 后，是直接可以使用iw wlan0 命令搜索到wifi 列表，

说明内核是正常加载的，后面发现是binder IWifi异常了，是hardware 层的服务无法连接，

并不是WifiManager到WifiService的 binder异常，

底层适配修改了 usb_inotify 、ko驱动和相关加载逻辑进行解决。

（3）iw dev 主要命令

iw 命令后面加上不同的参数，例如：

iw dev interface add 用于添加一个新的接口

iw dev del 用于删除一个接口

iw dev scan 用于扫描可用的无线网络

iw dev support 用于查看设备支持的参数

dev 表示不同的节点名称，比我wifi的 wlan0

请注意，某些命令可能需要root权限才能运行。

常用的就是：iw dev del，iw dev scan ，其他命令简单执行了一下，发现返回的提示数据非常多，有点看不懂。
