Help with PyBluez

[Piecat]

I installed it to the site-packages folder and installed NXT python
too.


When I run the example programs it claims I didn't install PyBluez. My
NXT is hooked up to windows and it says its working.


What the Idle says when I try to run them:
"
USB module unavailable, not searching there
Bluetooth module unavailable, not searching there
Traceback (most recent call last):
File "C:\Python\2.6\Lib\site-packages\nxt-python\examples\mary.py",
line 15, in <module>
b = nxt.locator.find_one_brick()
File "C:\Python\2.6\Lib\site-packages\nxt\locator.py", line 55, in
find_one_brick
for s in find_bricks(host, name, silent):
File "C:\Python\2.6\Lib\site-packages\nxt\locator.py", line 47, in
find_bricks
raise NoBackendError("Neither USB nor Bluetooth could be used! Did
you install PyUSB or PyBluez?")
NoBackendError: Neither USB nor Bluetooth could be used! Did you
install PyUSB or PyBluez?
"


Any idea what it could be?

Good.

Open a python shell and "import bluetooth". What output? What OS? What
version of nxt-python? Sorry you're having trouble.

I am using Windows 7, The version of python is 2.6 and the NXT-python version is 2.01.


The output I get from "import bluetooth" is:

"
Traceback (most recent call last):

  File "<pyshell#0>", line 1, in <module>
    import bluetooth
  File "C:\Python\2.6\lib\site-packages\bluetooth\__init__.py", line 31, in <module>
    from msbt import *
  File "C:\Python\2.6\lib\site-packages\bluetooth\msbt.py", line 2, in <module>
    import _msbt as bt
ImportError: DLL load failed: %1 is not a valid Win32 application.
"


And its okay, I have plenty of time and I know this contributes and helps so the problem doesn't happen to anyone else.


Also, I don't know if this matters but my NXT is the 1st version.

This looks bad...regular DLL hell if you ask me. I would guess that you
are using either an incompatible bluetooth stack (broadcom or bluesoleil
may not work with PyBluez; check their website) or the wrong
architecture (32 vs. 64 bit) of PyBluez. This isn't really a nxt-python
problem really...if neither of these things are the problem you'd be
best asking the PyBluez guys for help. Sorry...

Yes it does.

I don't think this would make a difference since we can't actually
connect to it yet.

I just realized that I am using the built in windows blue tooth which might be the problem. If it is ill just get one.

Also, I went to the Pybluez website and it has an error message, so I just got it from your guy's page.

wait, I have no idea which page I went to because there is a Google page for PyBluez...

It looks like it might only be for windows XP, ill email them.

Ill contact you again if I have anymore problems with NXT-Python.

No, that should work fine. At least, it did in WinXP. Make sure the
PyBluez guys support 7.
