When I read an input string from a Holux GPS puck the return value gets weird. BB JDE v4.3.0.1r
When I cast the byte to a char and convert to a String using String.valueOf() the end result is always: "unknown(net_rim_cldc,80)"
//Invoked when data has been received.
public void dataReceived(int length){
byte buf[] = new byte[256];
StringBuffer stringBuffer = new StringBuffer();
int len =0;
if((len = btPort.read(buf, 0, length == -1 ? buf.length : length)) != 0){
stringBuffer.setLength(0);
for(int i=0; i<len; i++){
char ch = (char)buf[i];
String st = String.valueOf(ch);
//here is where the value of st equals "unknown(net_rim_cldc,80)"
if(st!=null && !st.equals(""))
stringBuffer.append(st);
}
String currentInfo = stringBuffer.toString();
//the value of currentInfo equals "unknown(net_rim_cldc,80)"
}
}
The value of the byte array (buf) after the read =
"$GPGGA,143754.000,2501.6\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000"
Has anyone seen this before?
I open the port like this:
btPort = new BluetoothSerialPort(btInfo, BluetoothSerialPort.BAUD_115200, BluetoothSerialPort.DATA_FORMAT_PARITY_NONE | BluetoothSerialPort.DATA_FORMAT_STOP_BITS_1 | BluetoothSerialPort.DATA_FORMAT_DATA_BITS_8, BluetoothSerialPort.FLOW_CONTROL_NONE, 256, 256, this);
