Arduino Serial Monitor line length limit?

Hi, yes thanks for your input.

I have a Bluetooth module with RX/TX on pins 10 & 11 using the SoftwareSerial.h library.

This enables two-way comms with no problems, i found for example that when I connected the Bluetooth module to pins 0 and 1 although I got it working I'd have to take the module off each time I wanted to upload a sketch so for my application the SoftwareSerial library is the way to go so my routine:

   if (Serial.available()) softSerial.write(Serial.read()); // send from Arduino to Bluetooth
   while(softSerial.available() > 0) { // While there is more to be read, keep reading.
     command += (char)softSerial.read();
     delay(1);
   }

is the same as yours, I find at the moment that a delay of 1 does the job nicely.

I don't want to have to use delimiters but appreciate the advice.

Thanks!
