- Fri Apr 01, 2016 9:53 am #44631 Hi, i am investigating why esp freezes after some reconnection

To do so, I've build this loop and noticed that after each connection I lose some heap space.

I am missing something? Is it common with you guys? I am using 2.1.0-rc2

Code: Select all       const char* host = "google.com";
   WiFiClient c;
   for (int i =0; i< 100; i+=1) {
      Serial.print (i);
      Serial.print ("-");
      Serial.println (ESP.getFreeHeap());
      if (c.connect (host,80)) {
         delay (100);
         c.flush ();
         c.stop ();
         delay (100);
      } else {
         Serial.println ("connection refused");
      }
   }

output:
