Unpack requires a string argument of length 16

[bertel76]

Hi

I´m trying to run this program on Ubuntu with a Garmin Forerunner 910XT. I got the program to run and pair with the device, then I get an error and the device hangs on Transferring data... The bottom of the stacktrace is below:

File "/home/bertel/Downloads/Garmin-Forerunner-610-Extractor-master/Garmin-Forerunner-610-Extractor-master/ant/fs/comman.py", line 85 in _parse args = cls._parse_args(data) File "/home/bertel/Downloads/Garmin-Forerunner-610-Extractor-master/Garmin-Forerunner-610-Extractor-master/ant/fs/comman.py", line 241 in _parse_args (date[16:-8],) + struct.unpack("<6xH",data[-8:]) error: unpack requires a string argument of length 16

Hello. I think this might be fixed on the split branch. Could you try that branch?

Tried it, almost there but not quite, started downloading fit files but then got the same error, maybe I should delete all the activities on the device except the one I´m trying to recover (Have already deleted most of them).

This is the stacktrace:

It worked ! I removed all the activities from the device except the one I was trying to recover and ran it again on the split branch. Many thanks for this software !
