Unsecure & secure connections simultaneously

PostPosted: Mon Jul 03, 2017 9:28 am

Hi.
I use this example to connect my esp8266 module to a telegram bot:
https://github.com/Gianbacchio/ESP8266-TelegramBot/tree/master/examples/FlashledBot

also I need to get Internet time & I use this function:

Code: Select allvoid get_exip(){
 
  String exip="";
  WiFiClient client;
  if (client.connect("api.ipify.org", 80)) {
    client.println("GET / HTTP/1.1");
    client.println("Host: api.ipify.org");
    client.println();
    while(client.available()){
      exip = client.readStringUntil('\n');
    }
  }
}


After programming the module, it keeps resetting. I found out that the problem is connection conflict but I don't have any clue to solve it. Could you please help me?

Regards!
sorry for my poor English.

Your reset problem is maybe due to something else elsewhere.
But for sure, in the above code, your are sending a request and expect to have response instantaneously, which is wrong !
You should add a delay() before your while(client.available()) or even better waiting for response with something like the following before reading this reponse :

Code: Select all    int timeout = millis() + 5000;
    while (client.available() == 0) {   
      if (timeout - millis() < 0) {
        Serial.println(">>> Client Timeout !");
        client.stop();
        return;
      }
    }

Hi.
Thanks for your response.
I removed the delay and some part of the code to clarify my purpose.
It seems the problem is somewhere else (maybe in the library).
Thanks a lot.

Hi.
I found out that the problem IS in the library. After trimming out small peaces of code, I got some results.
When I use a web server and a HTTPS connection at the same time, the problem appears.
It seems that using them at the same time, exhausts the memory.
Is there any solutions? I use esp-01.
Thanks in advance.

by the way, this is the error:

Code: Select allException (29):
