4  第四部分 扩展模块功能演示

4.1  RTL8188 模块功能演示（WIFI Client）

【测试说明】：使用RTL8188作为无线网卡连接到WIFI AP。
【接口标识】：WIFI、WIFI_ANT
【系统设备】：wlan0
测试操作
1. 确定“WIFI”标识处有贴上WIFI模块，否则无需进行测试。
2. 把WIFI天线连接到“WIFI_ANT”标识的接口上。
3. 生成 SSID 的 WPA PSK 文件
命令格式: wpa_passphrase [passphrase]

=====> 输入指令:

wpa_passphrase MY-TEST-AP myzr2012 > /etc/wpa_supplicant.conf

pkill wpa_supplicant

4. 连接

=====> 输入指令:

wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf

=====> 输出信息：

Successfully initialized wpa_supplicant

rfkill: Cannot open RFKILL control device

==> rtl8188e_iol_efuse_patch

IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

......

5. 获取 IP

=====> 输入指令:

udhcpc -i wlan0

=====> 输出信息：

udhcpc (v1.23.1) started

Sending discover...

Sending select for 192.168.43.121...

Lease of 192.168.43.121 obtained, lease time 3600

/etc/udhcpc.d/50default: Adding DNS 192.168.43.1

6. 测试连接

=====> 输入指令:

ping -I wlan0 192.168.43.1 -c 2 -w 4

=====> 输出信息：

PING 192.168.43.1 (192.168.43.1) from 192.168.43.130 wlan0: 56(84) bytes of data.

64 bytes from 192.168.43.1: icmp_seq=1 ttl=64 time=5.66 ms

64 bytes from 192.168.43.1: icmp_seq=2 ttl=64 time=9.22 ms

2 packets transmitted, 2 received, 0% packet loss, time 1000ms

rtt min/avg/max/mdev = 5.663/7.444/9.226/1.783 ms

测试结果
“0% packet loss”表示WIFI连接正常。

4.2  RTL8188 模块功能演示（WIFI AP mode）

【测试说明】：使用RTL8188作为WIFI AP，并把手机连接到此AP。
【接口标识】：WIFI、WIFI_ANT
【系统设备】：wlan0
测试操作
1. 确定“WIFI”标识处有贴上WIFI模块，否则无需进行测试。
2. 把WIFI天线连接到“WIFI_ANT”标识的接口上。
3. 为 wlan0 配置 IP：

=====> 输入指令:

ifconfig wlan0 192.168.99.1

=====> 输出信息：

==> rtl8188e_iol_efuse_patch

IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

4. 为 wlan0 启用 DHCP 服务：

=====> 输入指令:

touch /var/lib/misc/udhcpd.leases

udhcpd -f /etc/my_udhcpd.conf &

=====> 输出信息：

[1] 469

udhcpd (v1.23.1) started

5. 为 wlan0 启用 Host-AP 功能

=====> 输入指令:

hostapd /etc/my_hostapd.conf -B

=====> 输出信息：

Configuration file: /etc/my_hostapd.conf

rfkill: Cannot open RFKILL control device

Using interface wlan0 with hwaddr e0:b9:4d:7f:e4:40 and ssid "MY_HOSTAP_V25"

RTL871X: set group key camid:1, addr:00:00:00:00:00:00, kid:1, type:AES

wlan0: interface state UNINITIALIZED->ENABLED

wlan0: AP-ENABLED

6. 客户端设备连接到 Host-AP
至此，开发板的 Host-AP 功能已启用，客户端设备可搜索“MY_HOSTAP_V25”，通过密码“myzr2012”连接到此AP。
测试结果
1. 设备连接成功时产生的信息

=====> 输出信息：

Sending OFFER of 192.168.12.20

Sending OFFER of 192.168.12.20

Sending ACK to 192.168.12.20

2. 设备断开连接时产生的信息

=====> 输出信息：

RTL871X: OnDeAuth(wlan0) reason=3, ta=b4:0b:44:f5:64:2f

RTL871X: clear key for addr:b4:0b:44:f5:64:2f, camid:4

4.3  EC20 模块测试

【测试说明】：4G连接成功后，开发板向外网发送ICMP报文来验证连接正常。
【接口标识】：MINI_PCIE
【系统设备】：eth2
测试操作
1. 开发板断电，接上4G模块，接上天线并插入SIM卡后启动评估板。
2. 使用指令进行网络连接：

=====> 输入指令:

/my-demo/gcc-linaro-5.3-arm/quectel-CM &

=====> 输出信息：
