Unknown Error (22, 'Invalid argument') #22

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
This problem occured on version 0.16 (unpatched).
It is impossible to connect any device with the regular connect() function,
on a L2CAP socket.

A tiny script like :
import bluetooth.bluez

mac = '00:11:22:33:44:55'
recv = bluetooth.bluez.BluetoothSocket(bluetooth.L2CAP)
ctrl = bluetooth.bluez.BluetoothSocket(bluetooth.L2CAP)

recv.connect ((mac, 0x13))
ctrl.connect ((mac, 0x11))

if recv and ctrl :
    print "ok"
else:
    print "nok"

would raise a BluetoothError exception.

Traceback (most recent call last):
  File "./test.py", line 15, in <module>
    recv.connect ((mac, 0x13))
  File "<string>", line 5, in connect
bluetooth.btcommon.BluetoothError: (22, 'Invalid argument')

This occured on :
- Fedora 11 Leonidas (tested on x86_64 and x86)
- PyBluez 0.16 (tested with RPM and regular SVN)
- bluez 4.42

Found a patch (attached) on the following page that seems to be working:
http://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg660555.html

Works like a charm with this patch !

Hi,

I believe this is fixed in the new 0.17 release.  Please test it if you have a
chance, and let me know so I can close this issue.

On ubuntu 9.10 with 2.6.31 kernel, this issue occured with the 0.17 too.
The same patch works.

I confirm what darkevolution just said. It still doesn't work without the patch 
on 
0.17.

Ok, I've no idea why the patch should make any difference, but I'll apply it 
anyway
since I don't have a 2.6.30+ machine to test on, and the patch looks fairly 
innocuous
otherwise.

Hi,

I assume this patch has been applied to 0.18.

Unfortunately, I still get the error message above with Ubuntu 9.10,
2.6.31-15-generic kernel and bluez 4.58 :-(

Correct, the patch has been applied to 0.18.  Well, it's a bummer it still 
doesn't
work, since a lot of people are migrating to 9.10 now.  Unfortunately, I 
currently
don't have time to look into this myself...

This patch worked for me too, Fedora 12 with pybluez 0.18.
Daniel.Chr.Schmidt2, are you sure you use pybluez 0.18? How did you install it?
If you compiled it from source, could it be that there is still an older 
version on 
your system, for example one from your package manager?
What does python -c "import bluetooth; print bluetooth.__path__" report?

Thank you very much for your help. You were right, I actually had the 
0.16-ubuntu
package installed as well, of which I wasn't aware of. Removing it fixed my 
problems. :-)
