嵌入式系统中启动Hostapd

# 构造 WiFi AP 参数，其中 ssid 和 wpa_passphrase 分别对应 SSID 和 密码， 例如此配置文件对应的 SSID 是 rokid，密码是 rokidos_psk

# 创建虚拟网卡　
iw wlan0 interface add wlan1 type managed

# 启动 hostapd (AP 管理软件)
hostapd -B /etc/hostapd_temp.conf

# 配置网卡的 IP 地址
ifconfig wlan0 192.168.2.1

# 启动 dns 和 dhcp 服务， 其中注意 IP 参数要与 IP 地址相对应

		Add a new virtual interface with the given configuration.
		Valid interface types are: managed, ibss, monitor, mesh, wds.
		
		The flags are only used for monitor interfaces, valid flags are:
		none:     no special flags
		fcsfail:  show frames with FCS errors
		control:  show control frames
		otherbss: show frames from other BSSes
		cook:     use cooked mode
		active:   use active mode (ACK incoming unicast packets)
		
		The mesh_id is used only for mesh mode.
