I noticed that there is hardReset function in the base cpp file. Where you set the pin high and low how is this schematic supposed to look like on the esp chip.

i try to use connectAP (wifi looping connection) but the wifi does not work.
But if i remove the connectAP the wifi works.

i think the reset did not work well.

  // Check that ESP8266 is available
  if(wifi.test())
  {
  // Connect to target Access Point
  String ip = connectAP();

  // but if remark this the wifi works, somethig like this
  // //String ip = connectAP();
  // so the reset did not work, maybe they use the old configuration

  // Open TCP Server on port 2000 and 30 seconds for connection timeout (Max 2880)
  

  wifi.openTCPServer(2000, 7200);
  }
  else
  {
  // ESP8266 isn't available
  Serial.println("Check module connection and restart to try again...");
  while(true);
  }
  }

anyone can help me?

Hi,

This is venkat,Please ,I would request you to clear one of my doubt.i was using the following library for communication
https://github.com/INEXTH/Arduino-ESP8266_libs

Server is created and when i am starting server to make communication between them iam getting the following error which was marked.

AT+CIPSTART=(4)("TCP"),("192.16ø.4.1"),(80)
Link typ ERROR

I am doing these commuinication using two esp8266 with two arduino boards.

​

Hi, I try send a lo of messages to the ESP8266 through TCP Java Sochet, but I lost many messages if i send the messages quickly.Can I change this?

Thanks

how to reconnect TCP connection automatically?

i try to use timeout 7200 seconds (2 hours) its ok, but if i use more than 7200 seconds times make it wrong.

actually in the esp8266 datasheet maximum we can use 28800 seconds timeout so why goes error.

the soultion maybe we must reconnect TCP connection automatically after 7200 seconds max.

anyone can help me.

regards

Thanks

I am unable to send messages after making a successful connection through this function. But when i use the AT command from Serial Monitor it works perfectly. Can you please check?
