cannot If readString statements

[maco1717]

Hi,

I'm trying to do stuff on accordance to what i receive on readString but my if statement are not working.

I've also tried saving the result to a variable, when I do this, it appears empty, altough if a print the information is coming in...

section of the code:

while (client.connected()) {
    int messageSize = client.parseMessage();

    if (messageSize > 0) {
      //Serial.println(client.readString());
      //String input = client.readString();
      String state0 = "off";
      String state1 = "on";

     // if (client.readString() == "off") {
     //if (strcmp(client.readString(), state0){
     //if (input == "off"){
     if (client.readString().equals(state0)){

        Serial.println("low");
        digitalWrite(6, LOW);
      }
      if (client.readString() == "on")  {
        Serial.println("high");
        digitalWrite(6, HIGH);
      }
    }
  }

Commented you can see some of the alteration I have tried but no luck...

could you please suggest?

Thanks.

My problem was that was trying to use the readString() more than once. and apprently once used it empty's the buffer, I start by storing readString() on a String varible object and use that, that worked...

if (messageSize > 0) {
      //Serial.println(client.readString());
      String input = client.readString();
      Serial.println(input);
