R329 EVB5开发板上集成了全志自研的XR829无线芯片，支持2.4G wifi 和BT功能。
Tina Linux系统对无线功能进行集成，可以直接使用内置DEMO连接wiff、BT。
这里主要演示wifi demo 。

首先需要确保开发板上贴上了天线，否则会因为信号强度过弱连接失败。
R329 EVB5开发板标准装中随盒附赠了一根天线。

WiFi 命令
在终端输入命令行 wifi 然后按 TAB键 补全，会看到系统下内置了大量wifi相关的命令，包括打开、关闭、扫描、连接、中文连接、移除等。

root@TinaLinux:/# wifi_
wifi_connect_ap_test wifi_off_test
wifi_connect_ap_with_netid_test wifi_on_off_test
wifi_connect_chinese_ap_test wifi_on_test
wifi_disconnect_ap_test wifi_reconnect_ap_test
wifi_get_connection_info_test wifi_remove_all_networks_test
wifi_get_netid_test wifi_remove_network_test
wifi_list_networks_test wifi_scan.sh
wifi_longtime_scan_test wifi_scan_results_test
wifi_longtime_test wifi_wps_pbc_test

搜索附近WiFi
输入 wifi_scan_results_test ，即可搜索到附近的wifi信号，会显示bssid、频率、信号强度、加密方式和SSID等信息：

root@TinaLinux:/# wifi_scan_results_test
