Not a whole lot to say here other than this doesn't work, and I have no idea why.
The serial output on the Arduino is nothing. The output on the C# code goes down to waiting for a response and then nothing.
The Bluetooth card LED on the Arduino goes green when I start the C# program so there is a connection being made. Just nothing else.
Arduino Code
#include <SoftwareSerial.h> //Software Serial Port
#define RxD 8 // This is the pin that the Bluetooth (BT_TX) will transmit to the Arduino (RxD)
#define TxD 7 // This is the pin that the Bluetooth (BT_RX) will receive from the Arduino (TxD)
SoftwareSerial blueToothSerial(RxD,TxD);
boolean light = false;
void setup(){
Serial.begin(9600); // Allow Serial communication via USB cable to computer (if required)
pinMode(RxD, INPUT); // Setup the Arduino to receive INPUT from the bluetooth shield on Digital Pin 6
pinMode(TxD, OUTPUT); // Setup the Arduino to send data (OUTPUT) to the bluetooth shield on Digital Pin 7
pinMode(13,OUTPUT); // Use onboard LED if required.
}
void loop(){
delay(1000);
if(light){
light = false;
digitalWrite(13,LOW);
}
else{
light = true;
digitalWrite(13,HIGH);
}
//Serial.println(blueToothSerial.available());
blueToothSerial.write("Im alive");
if(blueToothSerial.read()>0){
Serial.write(blueToothSerial.read());
}
}
Core C# Code
static void Main(string[] args)
{
byte[] Command = Encoding.ASCII.GetBytes("It works");//{0x00,0x01,0x88};
SerialPort BlueToothConnection = new SerialPort();
BlueToothConnection.BaudRate = (9600);
BlueToothConnection.PortName = "COM4";
BlueToothConnection.Open();
if (BlueToothConnection.IsOpen)
{
BlueToothConnection.ErrorReceived += new SerialErrorReceivedEventHandler(BlueToothConnection_ErrorReceived);
// Declare a 2 bytes vector to store the message length header
Byte[] MessageLength = { 0x00, 0x00 };
//set the LSB to the length of the message
MessageLength[0] = (byte)Command.Length;
//send the 2 bytes header
BlueToothConnection.Write(MessageLength, 0, MessageLength.Length);
// send the message itself
System.Threading.Thread.Sleep(2000);
BlueToothConnection.Write(Command, 0, Command.Length);
Messages(5, ""); //This is the last thing that prints before it just waits for response.
int length = BlueToothConnection.ReadByte();
Messages(6, "");
// retrieve the reply data
for (int i = 0; i < length; i++)
{
Messages(7, (BlueToothConnection.ReadByte().ToString()));
}
}
}
