Howto test your Bluetooth Bee - Standalone

2012-07-26T08:15:00.003+07:00

Steps:

1] to be able to program this Bee, you need XBee Carrier,

or with UartSBee (but make sure to set the operation voltage to 3.3V)

2] download this software for Arduino-1.0 (the program do : set -> slave mode, wait for connection)
note: set board to Arduino Nano w/ ATmega168 seems to be fine

.

3] after Done uploading, can get the response from serial monitor as follow:

4] you may connect using PC

- Add a bluetooth device : will see your device:

- select the icon and press Next, then enter the device's pairing code = 0000

Hope this will help:

Next step:

- pairing 'Bluetooth Bee - Standalone' with the other 'Bluetooth Bee - Standalone'

BTW: I have a program so you can send command to 'Bluetooth Bee - Standalone' using serial monitor as follow: (so you can set the other to be Master, make connect etc., don't forget to send '\r\n' which can be done with ... )

- sendCommand via serial-terminal

- IDE v1.0.1 (using Nano-168)

- To program the Arduino : connected with PC using either UartSBee or XBee carrier

note: to use v1.0

- #include <NewSoftSerial.h> -> #include <SoftwareSerial.h>

- NewSoftSerial blueToothSerial(RxD,TxD); -> SoftwareSerial blueToothSerial(RxD,TxD);

#include <SoftwareSerial.h> //Software Serial Port

#define RxD 2 // RxD=2,TxD=3 : specific for Bluetooth Bee-Standalone

#define TxD 3

#define DEBUG_ENABLED 1

//NewSoftSerial blueToothSerial(RxD,TxD);

SoftwareSerial blueToothSerial(RxD,TxD);

String inputString = ""; // a string to hold incoming data

boolean stringComplete = false; // whether the string is complete

void setup()

{

Serial.begin(9600);

pinMode(RxD, INPUT);

pinMode(TxD, OUTPUT);

// reserve 100 bytes for the inputString:

inputString.reserve(100);

pinMode(5,OUTPUT);

blueToothSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400

delay(1000);

}

void loop()

{

// print the string when a newline arrives:

if (stringComplete) {

Serial.println(inputString);

blueToothSerial.println(inputString);

// clear the string:

inputString = "";

stringComplete = false;

}

if (blueToothSerial.available())

Serial.write(blueToothSerial.read());

}

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;

}

void setupBlueToothConnection()

{

blueToothSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400

delay(1000);

sendBlueToothCommand("\r\n+STWMOD=0\r\n"); // 0 = slave
