v8.0: Edge 530 no longer reporting threshold hr in zones_target message?

After upgrading to v8.0 of software on the Edge 530, two issues noted in the fit file:

  1. the unit is reporting zero for the threshold_heart_rate in the zones_target message
  2. the unit does not report max_heart_rate in the zones_target message at all

functional_threshold_power is reported in the zones_target message as set in user settings

Is this an error in v8.0 software?

Thanks

    How are you parsing the data as some of it did move locations?

    Could you post the FIT file you are looking at.

    Also it would be good to get the settings.fit file from both the Settings folder and the Garmin\Debugging\Backup folder

    Parsing via FIT SDK 21.32.  Also seen using FIT file viewer: https://www.fitfileviewer.com/

    Settings in Garmin Connect, which are mirrored on the Edge 530:

    settings.fit from the Settings folder and from the Debugging\Backup folder - interesting that zones_target is different across the two.

    Thanks. I will take a look. The latest SDK is 21.54

    I think the HR boundaries look correct as does the threshold. I'm using SDK 21.54

    What I think is missing is your resting heart rate value. Check that on the unit.

    hr_zone_high_boundary 80|112|136|156|172|180

    threshold_heart_rate 164

    Added resting heart rate and my quick little test showed same entry in zones_target

    zones_target

    1 row(s)
    functional_threshold_power threshold_heart_rate hr_calc_type pwr_calc_type
    267 0 percent_max_hr percent_ftp

    My guess is that v8.0 software is using whatever the different lines are in zones_target in settings.fit differently (and therefore not picking up changes in HR fields)

    From the settings.fit file - valid HR info on row "0" and valid FTP on row 2, and it looks like row 2 is replicated in the activity.fit file above (likely including a null max HR)

    zones_target

    5 row(s)

    0 200 180 164 3 percent_ftp 0 1 0 0 9
    1 200 - 0 percent_max_hr percent_ftp 1 1 0 0 7
    2 267 - 0 percent_max_hr percent_ftp 1 1 0 1 7
    3 200 - 0 percent_max_hr percent_ftp 1 1 0 0 7
    4 200 - 0 percent_max_hr percent_ftp 1 1 0 0 7
    Updating the settings on the unit reflects resting HR in user_profile.

    FWIW, implemented SDK v21.54.01 <gulp>.  I still see the same issue.

    Figured out a fix/work-around: enable "Cycling" version of Heart Rate Zones in Garmin Connect

    The unit then reports these out in zones_target.

    Sorry I was looking at the time in zone record and not the zones target record.

    No worries - pointing to the settings.fit file got the brain thinking - and then I saw the option to add a cycling version of HR zones and it clicked.
