bluez

I have these snippet in python with pybluez framework: from bluetooth import * server_sock=BluetoothSocket( RFCOMM ) server_sock.bind(("",PORT_ANY)) server_sock.listen(1) port = server_sock.getsockname()[1] uuid = "94f39d29-7d6d-437d-973b-fba39e49d4ee" advertise_service( server_sock, "SampleServer", service_id = uuid # service_classes = [ uuid, SERIAL_PORT_CLASS ], # profiles = [ SERIAL_PORT_PROFILE ], # protocols = [ RFCOMM_UUID ] ) print "Waiting for connection on RFCOMM channel %d" % port client_sock, client_info = server_sock.accept() print "Accepted connection from ", client_info try:

I am new to BLUEZ as well as linux. I found that Bluez promotes usage of DBUS APIs. I want to know whats a DBUS API in terms of BLUEZ also, whats the benefit of using them instead of direct C APIS? How different is it as compared to C APIs? From my own experience: DBUS apis are the officially published ones so are more likely to be stable, maintained and documented. The C apis are a bit more low level and it's not always obvious how they can be used (beyond simple discover). The C apis are more light weight whereas the DBUS APIs require more both at build time and at run time (glib, dbus,

I connect to five devices by spawning gatttools with pexpect in python*. When I try to connect to a sixth device (using the same CSR 4.0 dongle for all connections) manually I encounter: sudo gatttool -b DC:05:4F:BC:F6:4A -It random [DC:05:4F:BC:F6:4A][LE]> connect Attempting to connect to DC:05:4F:BC:F6:4A Error: connect error: Too many links (31) Is this a gatttool limitation or a hardware limitation? I cloned the source at http://git.kernel.org/cgit/bluetooth/bluez.git and ran grep -r "attempting" but did not get any results. I would like to connect to 20 devices over bluetooth low energy,

I am trying to connect a bluetooth headset to my RPI. My setup is the following: archlinux-arm, kernel: linux-raspberrypi 3.12.23-1 bluez4 4.101-4 from AUR , built and installed bluez-tools 0.1.38-3 bluez-utils 5.20-1 pulseaudio 5.0-1 pulseaudio-alsa 2-3 I scan for the device, successfully pair it, add as trusted and connect it: hcitool scan bluez-simple-agent hci0 <MAC> bt-device --set <MAC> Trusted 1 bt-audio -c <MAC> After this, the device state is as follows ( bt-device -i <MAC> output): [00:23:7F:2A:3B:24] Name: PLT 510 Alias: PLT 510 [rw] Address: 00:23:7F:2A:3B:24 Icon: audio-card Class

I am trying to establish bluetooth communication between an Arduino Uno board (with a bluetooth shield) and my Linux OS, using Python PyBluez. 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. Here is the Arduino Sketch #include <SoftwareSerial.h> #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);

Can anyone please provide us any source code for bluez implementation in android. Actually we are trying to make an application with GATT profile. This android application should connect with other device by Bluetooth connection. Please suggest me what should be the best way to send data to a non android device. Look at Bluetooth chat example by Google, you also can use the same method to connect to a non android device. Specifically you will need this api device.createRfcommSocketToServiceRecord(SerialPortServiceClass_UUID); EDIT: You can also try using reflection to access another method

How can I rebuild bluez? Is it possible? Lets just say I want to change something in avctp.c for example. I download the latest bluez release from their website and make the change I need to make. Now, how do I get the changes to be effective; i.e. what do I need to do to rebuild bluetoothd? Note: I am using Ubuntu 12.04 The quickest way to do this is just to remake the whole bluez package with the following commands: ./configure make make install After that, you can run the configured bluetoothd executable form the /src directory by using ./bluetoothd , or replacing the bluetoothd in /usr
