ESP8266WiFi STA WL_CONNECTED WL_NO_SSID_AVAIL WL_CONNECT_FAILED WL_IDLE_STATUS WL_DISCONNECTED - WiFi.begin() 开始wifi连接 - WiFi.config(local_ip, gateway, subnet, dns1, dns2) Change IP configuration settings disabling the dhcp client 参数 local_ip Static ip configuration gateway Static gateway configuration subnet Static Subnet mask dns1 Static DNS server 1 dns2 Static DNS server 2 返回：bool - WiFi.reconnect() will force a disconnect and then start reconnecting to AP 返回：bool - WiFi.disconnect(bool wifioff) Disconnect from the network 返回：bool - WiFi.isConnected() 检查是否已连接 返回：bool - WiFi.setAutoConnect(bool autoConnect) 设置是否复位自动连接，默认自动连接 返回：bool - WiFi.setAutoConnect() 检查是否设置了复位自动连接 返回：bool - WiFi.setAutoReconnect(bool autoReconnect) 设置当连接断开时是否重新连接 返回：bool - WiFi.waitForConnectResult() Wait for WiFi connection to reach a result returns the status reached or disconnect if STA is off 返回：连接状态 WL_CONNECTED WL_NO_SSID_AVAIL; WL_CONNECT_FAILED; WL_IDLE_STATUS; WL_DISCONNECTED; - WiFi.localIP() 获取IP地址，用于STA模式 返回：IPAddress - WiFi.macAddress(uint8_t* mac) 获取MAC地址，用于STA模式 返回：uint8_t* - WiFi.macAddress(void) 获取MAC地址，用于STA模式 返回：String - WiFi.subnetMask() Get the interface subnet mask address. 返回：IPAddress - WiFi.gatewayIP() Get the gateway ip address. 返回：IPAddress - WiFi.dnsIP(uint8_t dns_no) Get the DNS ip address. 返回：IPAddress - WiFi.hostname(void) Get ESP8266 station DHCP hostname 返回：String - WiFi.hostname(char* aHostname) Set ESP8266 station DHCP hostname 返回：bool - WiFi.hostname(const char* aHostname) Set ESP8266 station DHCP hostname 返回：bool - WiFi.hostname(String aHostname) Set ESP8266 station DHCP hostname 返回：bool - WiFi.SSID() 获取当前连接网络的SSID 返回：String - WiFi.psk() 获取当前连接网络的共享秘钥 返回：String - WiFi.BSSID(void) Return the current bssid / mac associated with the network if configured 返回：uint8_t* - WiFi.BSSIDstr(void) Return the current bssid / mac associated with the network if configured 返回：String - WiFi.RSSI(void) Return the current network RSSI. 返回：int32_t (RSSI value) STA远程配置 - WiFi.beginWPSConfig(void) WPS配置（so far only WPS_TYPE_PBC is supported (SDK 1.2.0)） 返回：bool - WiFi.beginSmartConfig() 开始 SmartConfig 返回：bool - WiFi.stopSmartConfig() 停止 SmartConfig 返回：bool - WiFi.smartConfigDone() 查询 SmartConfig 状态，决定何时停止配置 返回：bool

ESP8266WiFi Server The Server class creates servers which can send data to and receive data from connected clients (programs running on other computers or devices). - Server - WiFiServer(IPAddress addr, uint16_t port) 开启服务 参数 addr：ip地址 port：端口 - WiFiServer(uint16_t port) 开启服务 参数 port：端口 - WiFi.begin() 开始 SmartConfig - begin() - available() - WiFi.available() 开始 SmartConfig - write() - print() - println()

ESP8266WiFi Client The client class creates clients that can connect to servers and send and receive data. - Client - WiFiClient() - connected() - connect() - write() - print() - println() - available() - read() - flush() - stop()

ESP8266WiFi Udp The UDP class enables UDP message to be sent and received. -WiFiUDP -begin() -available() -beginPacket() -endPacket() -write() -parsePacket() -peek() -read() -flush() -stop() -remoteIP() -remotePort()
