Bluetooth server with Python 3.3

bluetooth, python, python-3.x

Solution

Bad news: Python doesn't appear to support what you want to do out of the box. (At least not in socketmodule.c).

Most of the python/bluetooth users I've seen use `pybluez` although it hasn't been updated since 2009.

Good news: I went through their source (for Linux connections), and found the relevant bits for advertising services. Most of the code is essentially copy-pasted from the python 2.2 version of `socketmodule.c`.

`pybluez` does define some additional functionality for a `socket` object to implement all those bluetooth goodies. It doesn't get too low-level, and instead depends on `BlueZ` for that. From what I can tell, it basically takes python objects and creates the data structures expected by `BlueZ` and just calls that. If you don't want to/can't use `pybluez`, you'll have to somehow implement this missing functionality. I think you may be able to do it with c-types. The relevant parts for advertising the service are in btmodule.c, lines 2562-2642.

There is a python-3 branch in the source for `pybluez`, although I don't know if it works or not.

If you do decide to use `pybluez`, an example taken from their source

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 ], 
                  )

As google code is closing, the code can also be found on github here.

Problem

Python 3.3 came with native support for bluetooth sockets. Unfortunately, it's not too well documented yet (there is only one mention of it in the documentation). Googling it there is a blog post about implementing a client, but I couldn't find anything about creating a server. More specifically, how to set the user-friendly name and advertise the service. So, something like ``` import socket serverSocket = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_STREAM, socket.BTPROTO_RFCOMM) serverSocket.setTimeout(1) serverSocket.bind(("", 1)) serverSocket.listen(1) something.advertise_service(something something) ``` Any ideas?
