connect and disconnect on loop - losing memory
Posted: Fri Apr 01, 2016 9:53 amHi, 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
output:

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:
