Hi, I found this code in the examples...
What I basically need to do is accept incoming data from bluetooth serial port which is terminated by "/n". So I thought this would be a good starting point.
I uploaded this code to my arduino, and paired my bluetooth phone with the bluetooth module connected to the arduino.
Do I also need to define the bluetooth serial pins (Rx,Tx). If they are define in the sketch, does that mean I've got a 2nd com port?
I'm getting a bit confused with bluetooth and serial ports. I'd like to send data using bluetooth serial com, and then check com 4 (usb connected com port I used to upload the sketch) to view my results.
/*
Serial Event example
When new serial data arrives, this sketch adds it to a String.
When a newline is received, the loop prints the string and
clears it.
A good test for this is to try it with a GPS receiver
that sends out NMEA 0183 sentences.

String inputString = ""; // a string to hold incoming data
boolean stringComplete = false; // whether the string is complete
void setup() {
// initialize serial:
Serial.begin(9600);
// reserve 200 bytes for the inputString:
inputString.reserve(200);
}
void loop() {
// print the string when a newline arrives:
if (stringComplete) {
Serial.println(inputString);
// clear the string:
inputString = "";
stringComplete = false;
}
}
/*
SerialEvent occurs whenever a new data comes in the
hardware serial RX. This routine is run between each
time loop() runs, so using delay inside loop can delay
response. Multiple bytes of data may be available.
*/
void serialEvent() {
while (Serial.available()) {
// get the new byte:
char inChar = (char)Serial.read();
// add it to the inputString:
inputString += inChar;
// if the incoming character is a newline, set a flag
// so the main loop can do something about it:
if (inChar == '\n') {
stringComplete = true;
}
}
