Arduino WiFi101 - WiFi.status()用法及代码示例

说明

返回连接状态。

用法

WiFi.status();

参数

空

WL_CONNECTED：连接到WiFi网络时分配； WL_AP_CONNECTED：当设备以接入点模式连接时分配； WL_AP_LISTENING：在接入点模式下监听连接时分配； WL_NO_SHIELD：当不存在WiFi屏蔽时分配； WL_IDLE_STATUS：它是WiFi时分配的临时状态。begin()被调用并保持活动状态，直到尝试次数到期(导致WL_CONNECT_FAILED)或建立连接(导致WL_CONNECTED)； WL_NO_SSID_AVAIL：当没有SSID可用时分配； WL_SCAN_COMPLETED：扫描网络完成时分配； WL_CONNECT_FAILED：在所有尝试连接失败时分配； WL_CONNECTION_LOST：连接丢失时赋值； WL_DISCONNECTED：断开网络时分配；

示例


#include <SPI.h>
#include <WiFi101.h>

char ssid[] = "yourNetwork";                     // your network SSID (name)
char key[] = "D0D0DEADF00DABBADEAFBEADED";       // your network key
int keyIndex = 0;                                // your network key Index number
int status = WL_IDLE_STATUS;                     // the Wifi radio's status

void setup() {
  //Initialize serial and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }

  // check for the presence of the shield:
  if (WiFi.status() == WL_NO_SHIELD) {
    Serial.println("WiFi shield not present");
    // don't continue:
    while (true);
  }

  // attempt to connect to Wifi network:
  while ( status != WL_CONNECTED) {
    Serial.print("Attempting to connect to WEP network, SSID: ");
    Serial.println(ssid);
    status = WiFi.begin(ssid, keyIndex, key);

    // wait 10 seconds for connection:
    delay(10000);
  }

  // once you are connected :
  Serial.print("You're connected to the network");
}

void loop() {
  // check the network status connection once every 10 seconds:
  delay(10000);
 Serial.println(WiFi.status());
}
