    <p>I am trying to establish bluetooth communication between an Arduino Uno board (with a bluetooth shield) and my Linux OS, using Python PyBluez.</p> <p>I've successfully paired my laptop to the Uno. I'm able to connect to the board, however the board is not reading the data being sent nor is it able to send data.</p> <p>Here is the Arduino Sketch</p> <pre><code>#include &lt;SoftwareSerial.h&gt; #define RxD 0 //receive data on digital 0 #define TxD 1 //transmit on digital 1 SoftwareSerial blueToothSerial(RxD, TxD); int counter = 0; int incoming; void setup(void){ Serial.begin(9600); //pinMode(RxD,INPUT); //pinMode(TxD,OUTPUT); setupBlueToothConnection(); } void setupBlueToothConnection(){ blueToothSerial.begin(19200); blueToothSerial.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode blueToothSerial.print("\r\n+STNA=SeeedBTSlave\r\n"); //set the bluetooth name as "SeeedBTSlave" blueToothSerial.print("\r\n+STOAUT=1\r\n"); // Permit Paired device to connect me //blueToothSerial.print("\r\n+STAUTO=0\r\n"); // Auto-connection should be forbidden here delay(2000); // This delay is required. blueToothSerial.print("\r\n+INQ=1\r\n"); //make the slave bluetooth inquirable Serial.println("The slave bluetooth is inquirable!"); delay(2000); // This delay is required. blueToothSerial.flush(); } void loop(){ if(blueToothSerial.available()) Serial.println(blueToothSerial.read()); blueToothSerial.write('x'); } </code></pre> <p>And my Python Module:</p> <pre><code>import bluetooth import sys bd_addr = "00:12:10:23:10:18" #itade address port = 1 sock=bluetooth.BluetoothSocket( bluetooth.RFCOMM ) sock.connect((bd_addr, port)) print 'Connected' sock.settimeout(1.0) sock.send("x") print 'Sent data' data = sock.recv(1) print 'received [%s]'%data sock.close() </code></pre> <p>I have Arduino IDE 1.0.4, my laptop is running Ubuntu 11.10</p>

    1. COCan you send and receive data to/from Arduino board using Serial Monitor inside Arduino IDE?

    2. COSeems to work for me. I uploaded your script on my Arduino Uno. And executed the python script. This is the result: `user@ubuntu:~/$ python w.py Connected Sent data received [2]`. Are you sure that you have working connection to your Arduino and Bluetooth device?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
