Problem with strings?

Projects Programming

Hello,
i've got a strange problem and i really don't understand what to do!

This is the code:

    if (client.connect("192.168.1.66", 80)) {
    Serial.println("connected");
    client.println("GET /openenergymonitor/api/post?apikey=5eb553b60df99202de5846fb306792e3 HTTP/1.0");
    Serial.println("disconnecting.");
    client.stop();
  }

When i upload the program (compile without errors) the arduino ethernet will remain locked and doesn't execute the code.
If i remove the line with the "GET..." string it works.
Do i have to write special characters in a different way?

Thanks!

Do this instead:

  client.println(F("GET /openenergymonitor/api/post?apikey=5eb553b60df99202de5846fb306792e3 HTTP/1.0"));

Does that work?

Hello,
yes, now it works. But why?
What's difference in using flash instead of internal memory?

Thanks,
Bruno

You have lots of flash, not much SRAM.
