Some value errors when running garminsync.py

[marbud]

When i try the GarminSync software out i get:

marbud@pest:~/Desktop/garmin-sync-0.2$ PYTHONPATH=/usr/share/python-support/python-elementtree:/usr/share/python-support/python-pyusb:/usr/share/pycentral/python-serial/site-packages/ sudo ./garminsync.py
Traceback (most recent call last):
  File "./garminsync.py", line 367, in <module>
    exit_value = garmin_sync.run()
  File "./garminsync.py", line 359, in run
    link = garmin.USBLink()
  File "/home/marbud/Desktop/garmin-sync-0.2/garmin.py", line 1627, in __init__
    packet = ''.join(chr(b) for b in packet)
  File "/home/marbud/Desktop/garmin-sync-0.2/garmin.py", line 1627, in <genexpr>
    packet = ''.join(chr(b) for b in packet)
ValueError: chr() arg not in range(256)

Probably something with my setup, but i just can't figure it out.. If i print out the "packet" contents before the join(chr(b) for b in backet) line, i get negative numers in the end...

I added some debug output.. I uploaded the changes.

Now i get the following output:

marbud@pest:~/Desktop/garmin-sync-0.2$ sudo python2.4 ./garminsync.py

Sorry for taking so long to fix this. I've now released 0.3, which should fix this problem. If you have any other problems, please file a new bug, providing the output of './garmin-sync -d usb.packet'.

Thanks!

Now my Forerunner305 syncs with only some minor warnings.

I thought the output might be of interest for you so here is the warnings:

marbud@pest:~/Desktop/garmin-sync-0.3$ sudo ./garmin-sync
/home/marbud/Desktop/garmin-sync-0.3/newstruct.py:40: DeprecationWarning: struct integer overflow masking is deprecated
  return apply(struct.pack, tuple(args))
/home/marbud/Desktop/garmin-sync-0.3/newstruct.py:40: DeprecationWarning: 'B' format requires 0 <= number <= 255
  return apply(struct.pack, tuple(args))

After that, it works just fine.
