Hi,

My fit decoding code has been working fine for years. I want to get the data off of a VIRBXE, but every file I have tried so far I get the error:

FIT decode error: File CRC failed. Error at byte: 0

I've updated to the FIT SDK to the latest version. Is there any reason I'm getting the CRC error? Or just luck so far all my files have been corrupt?

Hello FigBug,

What SDK are you using to decode the files? Would you be able to attach a file to this thread or send me a file that gives you this error?

Hi,

Here is a FIT file that is causing me issues. It imported into VIRB Edit just fine.
https://www.dropbox.com/s/cig9fd5qux9q4rr/2016-05-13-08-16-19.fit?dl=0

I'm using the C++ version of the FIT 20.00.00 SDK

My code looks like this:

fstream file(QDir::toNativeSeparators(filename).toLatin1().data(), ios::in | ios::binary);
 fit::Decode decode;
 fit::MesgBroadcaster broadcaster;

 if (!decode.CheckIntegrity(file)) 

CheckIntegrity fails.

Yep, the CRC checksum of this file isn't valid, so it's corrupt - in one way or another.

Cheers,

I upgraded the firmware in my virb and haven't seen the issue since. Maybe there was a bug in early versions.
