Serial.print a string object

Projects Programming
1

I know it is not possible to do a Serial.print(str), where str is a string obect, and get sensible output in the Serial monitor.

I tried this:

    //for (int nI = 0; nI < strData.length(); nI++)
    //    Serial.print(strData[nI]);
    //Serial.println("");

but it does not seem to work either.

So as there any other round about way to Serial.print a string object?

That statement is nonsense. First, there is no such thing as a string object. There is a String class; there can be String objects. Second, it IS possible to print a String object.

@boylesg, post your complete program - or (better still) a short complete program that illustrates your problem.

I have never had a problem with Serial.println("This is a test"); or Serial.println(receivedChars);
