ESP8266 WIFI_AP_STA模式

Question

我正在使用ESP8266。我被抓到了一个地方。如果你能帮助我，我会很高兴的。

我想做的项目是，ESP8266将连接到调制解调器，在连接后，它将开始作为接入点进行广播。从我的电脑我也想连接到ESP8266并发送修改数据。

当我用WiFi.mode(WIFI_AP_STA); /*1*/代码插入ESP8266时，ESP调制解调器没有连接。所以我无法将数据从计算机发送到修改器。

当我在//WiFi.mode(WIFI_STA); /*2*/代码中运行ESP8266时，它会连接到我的机器。我可以从我的计算机连接到ESP但它不发送数据。过了一会儿，我与调制解调器的连接断开了。

这是我想要问的问题。如何在AP和STA模式下定期运行ESP8266？

const char* password = "1234567890";//agin password
const char* host="192.168.4.1";   // hosted host

        Serial.println("There is an AP link"); 
        clientAP.print(cgv); // send incoming data to clientAP
      }
    }
    if(clientAP.connected()) {
      // If clientAP is connected

        clientSTA.print(cgv); // send incoming data to station
        cgv="";
      }
    }
  }
}

Answer 1

这是因为当你的softAP通道在1时，当你的AP +站通道移动到9.所以tcp连接被重置。你的问题已经在这里讨论了LINK

Answer 2

设置WiFi.mode(WIFI_AP_STA);，离开和if(WiFi.status() !=WL_CONNECTED)与虚空循环。 STA通常不会出现创建工作站的问题，但在WiFi.h lib的某些版本上，没有重新连接工作功能，请尝试一下，看看它是否有帮助！
