Syncing Vivofit 2: "error: unpack requires a string argument of length 16' (program.py:369)"
Opened this issue · 5 comments
Hi,
uhm ... I just installed openant and antfs-cli following this instruction (sorry, it's in german). Basically it tells me to get git, python, openant and antfs-cli and how to compile the latter two. Up to this it worked without showing an error message.
Interestingly, I didn't see anything about "Vivofit 2", which I own, anywhere. Still tried it - and ended up with the error message given in the title. I'll attach the complete logfile also.
Is this model/data format something your software is not yet aware of or is this a beginners mistake? Is there something I can do to make it work?

Thank you for reporting this. I'll try to look into this tonight!
It seems to fail on setting the time. For some reason it is not returning what I'm expecting. 24 bytes instead of 16, not sure what is correct - the ANT-FS documentation is somewhat lacking here.
Try prefixing the lines https://github.com/Tigge/antfs-cli/blob/master/antfs_cli/program.py#L196-L203 with a # and see if you can get any further.
For reference, I've asked for clarification in the ANT forums: https://www.thisisant.com/forum/viewthread/4618/.
Ok, so I tried what you suggested. Unfortunately there are two sets of program files:
./antfs-cli/antfs_cli
and
./antfs-cli/build/lib.linux-x86_64-2.7/antfs_cli
I have no idea which one will be called by the console command, so I tried adjusting either one - I don't have the impression that something changed:

As I'm not that much of a python guy, I'm not yet really sure what I was doing. But, strangely, I didn't see my own debug message either. Did I overlook it?
Can confirm that commenting out program.py and then rerunning sudo python setup.py install (maybe it would be nice not to run the installation with root permissions ❓ ) I got my files downloaded
