I have my own python-program to read activity.fit-files.

To test my program I use the activity.fit-file examples of the SDK 1.0 and 6.1 (ditto 3.1) and my own files from edge 500 (software 3.0).

To verify the results of my progamm I use the SDK contained activity.csv-files.

I have a problem with the Field serial_number of the file_id-message. I do not know what is unit32z. So I read the 4 byte of the field serial_number as unit32.

I get:

activity.fit-file-example SDK 1.0: my program shows: serial_number: 1000332
activity.csv-file-example SDK 1.0 shows: serial_number: 1000332 o.k.

activity.fit-file-example SDK 6.1: my program shows: serial_number: 2147483647
activity.csv-file-example SDK 1.0 shows: serial_number: 3843863754 not o.k.

activity.fit-file of my own edge 500 (software 3.0): my program shows: serial_number: 3839254484
my own edge 500 (software 3.0): display shows serial_number: 3839254484 o.k.


Why only in the example SDK 6.1 is a difference? Is it my fault? I may not reading unit32z as unit32?

or

in SDK 6.1 activity.csv is an error?



Thanks for an answer
     

I think everything is working ok. The sample activity file included in the SDK was updated in version 2.20. The file_id.serial_number in the new sample file is actually 2147483647 which your program seems to decode correctly.

activity.fit-file-example SDK 1.0: my program shows: serial_number: 1000332
activity.csv-file-example SDK 1.0 shows: serial_number: 1000332 o.k.

activity.fit-file-example SDK 6.1: my program shows: serial_number: 2147483647
activity.csv-file-example SDK 1.0 shows: serial_number: 3843863754 not o.k.

Here I think you mean
activity.csv-file-example SDK 1.0 shows: serial_number: 1000332

     

Thank you for answer,

Sorry, here is the correction of my question:

Please take a look at the example activity.csv-file SDK 6.1:

The example activity.fit-file contains 7f ff ff ff but the example activity.csv-file contains 3843863754 ?!

Thank you
     

-Sorry I misunderstood earlier. I looked at the activity.csv file itself and you are correct, it does not reflect the content of activity.fit. Your program is decoding the serial_number field correctly, I will fix the error in the example .csv file.      

Thank you for fix the discrepancy between binary and ascii in example activity file in new SDK 6.20
