Print raw-format of a telegram

[mrWheel]

How do I use this :

    /**
     * Returns the data read so far.
     */
    const String &raw() {
      return buffer;
    }

If it should do what I think... It would be very nice to be able to print the raw format of the telegram!

IIRC, you should be able to do:

  if (reader.available()) {
    Serial.println("Message:");
    Serial.println(reader.raw());
    MyData data;
    String err;
    if (reader.parse(&data, &err)) {
      // Parse succesful, print result
      data.applyEach(Printer());
    } else {
      // Parser error, print error
      Serial.println(err);
    }
  }

This is taken from the read.ino example, but with the first two printlns added. IOW, raw() returns the data read so far, but once you call parse(), the buffer is cleared again. So if you retrieve the buffer when available() is true, but before calling parse(), you should get the complete message. Note that the buffer does not include the leading / and the trailing checksum.

@mrWheel, could you confirm if my suggestion worked?

[matthijskooijman]

@mrWheel thanks for your response. HOwever, AFAICS your code does not print the raw, unparsed message which was the subject of this issue :-)

I would want to close this issue, but ideally by adding the raw printing to the read.ino example. But I only want that after making sure it actually works (and I do not have a DSMR-attached setup currently to test with, so I was hoping you could confirm).

@matthijskooijman Yes, the code is OK!

if (reader.available()) {
    Debugln("Message:");
    Debugln(reader.raw());
    MyData data;
    String err;
    if (reader.parse(&data, &err)) {
      // Parse succesful, print result
      data.applyEach(Printer());
    } else {
      // Parser error, print error
      Debugln(err);
    }
}

Output:
