Blinker 如何判断连接状态
我想通过获取连接状态来指示led，这样写：while(! Blinker.connect()) {
digitalWrite(WiFiLedPin, HIGH);
delay(100);
digitalWrite(WiFiLedPin, LOW);
delay(100);
}
digitalWrite(WiFiLedPin, HIGH);未连接成功时闪烁，连接成功后常亮。应该是不行的吧？
我测试使用上面这段代码，运行过几次没有问题，可是后来就连接不上服务器了，提示：
11:56:38.347 -> WiFi Connected.
11:56:38.347 -> IP Address:
11:56:38.347 -> 192.168.0.110
11:56:42.685 -> ERROR: Maybe you have put in the wrong AuthKey!
11:56:42.685 -> ERROR: Or maybe your request is too frequently!
11:56:42.685 -> ERROR: Or maybe your network is disconnected!
应该是那个while导致频繁连接，被服务器拒绝了吧？
我看了源码，这里应该是源码吧？arduino-1.8.13/libraries/blinker-library-dev_3.0/src/Blinker/BlinkerProtocol.h
<div> <span style="color: #0000ff;">int</span> <span style="color: #795e26;">connect</span>() { <span style="color: #af00db;">return</span> <span style="color: #001080;">isInit</span> ? <span style="color: #001080;">conn</span>-><span style="color: #795e26;">connect</span>() : <span style="color: #0000ff;">false</span>; }</div><div> <span style="color: #0000ff;">int</span> <span style="color: #795e26;">connected</span>()</div><div> {</div><div> <span style="color: #af00db;">if</span> (<span style="color: #001080;">isInit</span>)</div><div> {</div><div><span style="color: #008000;"> // if (conn->connected())</span></div><div><span style="color: #008000;"> // {</span></div><div><span style="color: #008000;"> // state == CONNECTED;</span></div><div><span style="color: #008000;"> // return true;</span></div><div><span style="color: #008000;"> // }</span></div><div><span style="color: #008000;"> // else</span></div><div><span style="color: #008000;"> // {</span></div><div><span style="color: #008000;"> // state = DISCONNECTED;</span></div><div><span style="color: #008000;"> // return false;</span></div><div><span style="color: #008000;"> // }</span></div><div> <span style="color: #af00db;">return</span> <span style="color: #001080;">conn</span>-><span style="color: #795e26;">connected</span>();</div><div> }</div><div> <span style="color: #af00db;">else</span></div><div> {</div><div> <span style="color: #001080;">state</span> = <span style="color: #0070c1;">DISCONNECTED</span>;</div><div> <span style="color: #af00db;">return</span> <span style="color: #0000ff;">false</span>;</div><div> }</div>这个 conn->connect() 到底是获取连接状态还是执行连接呢？我猜测大概率是执行连接。
那么，还有什么方法能获取到 WiFi 连接成功以及服务器连接成功的方法呢？这个方法应该是从服务器获取状态而非执行连接后返回的结果。
begin 方法没有返回值，无法作为判断。

参考的一位大佬程序，连接wifi时，LED闪烁，连接后，常亮
