Issue storing QR in EEPROM and transmitting over RS485

Projects Programming

So I changed the previous to this new version, but now everything is garbage, no legible text outputs. Did I do it wrong?

  // send “EEPROM: <uuid>” in one RS-485 transaction:
  {
    String banner = "New feeder detected with UUID: " + EEPROMUUID + "\n\n";
    digitalWrite(EnRS485, HIGH);
    Serial.print(banner);
    Serial.flush();
    digitalWrite(EnRS485, LOW);
  }

changed to this new version:

  sendserial("EEPROM: ");
  sendserial(EEPROMUUID);
  sendserial("\n\n");
