ESPT66的WiFi盾牌版本由WangTongze连接到arduino UNO

Question

对不起，我的英语不好。

我和Shield和Arduino UNO之间的通信有问题。这些是图像：

Wifi shield使用FTDI程序员与Arduino IDE进行通信。引脚已正确连接。当我想在屏蔽上添加代码时，“红色小盒子”上的引脚分别是1-DOWN，2-DOWN，3-UP，4-UP，所以一切都还好。当我使用Arduino IDE中的Wifi AP示例（文件 - >示例 - > ESP8266WiFi - > WifiAccesPoint）并将其上传到WiFiShield时，我可以在手机上看到WiFi网络。这是代码：

    WiFi.softAP(ssid, password);

    IPAddress myIP = WiFi.softAPIP();
    Serial.print("AP IP address: ");
    Serial.println(myIP);
    server.on("/", handleRoot);
  server.on("/toggle",toggle);

}

有一张照片来自手机：

当我按下按钮时，我可以从Arduino IDE的串行监视器中看到来自WebPage的消息，说明：“点击”

现在，存在大问题。当我将屏蔽连接到Arduino时，wifi网络仍然可见，我可以按下按钮，因为FTDI始终与USB COM10通信（在我的情况下）。

然后，当我将Arduino UNO连接到USB端口时，wifi网络仍处于活动状态。

但是当我使用FTDI与USB断开使用Wifishield通信时，仍然连接了Arduino UNO电缆，WiFi网络消失了。

所以，我只想将Arduino UNO连接到usb Arduino IDE，我想看到用wifi屏蔽创建的wifi网络可见。然后它将始终可见（同样当wifishield断开连接时，只连接UNO）我希望它发送消息，在这种情况下消息“Click”到Arduino UNO串行监视器。有任何想法吗？非常感谢你！

我想你应该检查你的电缆，两个端口：ard Tx，Rx - usb Tx，Rx
