Firmware v5.20 user discussion / feedback

The release announcement for firmware version 5.20 certainly makes this sound like a compelling update:

Changes made from version 4.70 to 5.20:

  • Added support for Connect IQ 1.3.0 SDK. See the Connect IQ 1.3.0 SDK for a list of new features.
  • Added support for broadcasting optical heart rate over ANT to other devices during an activity.
  • Added support for phone apps to subscribe for more frequent data updates.
  • Added support for Apple Media Service - users can now control any active music player, e.g. Spotify, as well as volume (requires iOS 8.0 and higher).
  • Fixed an issue in which text on some Connect IQ watch faces may not display correctly.
  • Several improvements to optical heart rate.
  • Various bug fixes and stability improvements.



I'd managed to hold off updating to firmware v4.70 (from v4.60) for many weeks – after transferring the firmware file to my watch but dismissed the update manually – after seeing all the reports of issues, especially around garbled notifications, but the other night the watch somehow got updated to v4.70 anyway. I might as well take the leap and go to v5.20, now that it appears in Garmin Express for me several minutes ago.

Who else is game? :)
  • Pace

    Having the same issue with pace. Jumping around from 7:00 to over 9+. Pace had always been pretty good in the past hopefully this gets fixed.

    Pace issue 5.20

    Same BIG issue with pace. The watch is now unusable as my pace and instant speed (km/h) are never stable and never realistic.... however today my VO2Max drop from 56 to 50 after this upgrade (I think calculation is linked to pace and as pace is wrong, calculation is wrong).

    Garmin, please fix ASAP !! We cannot use the watch with this big Bug...

    god damn this new update messes up my pace as well.
  • That would have meant you were to be prompted each and every time you prepped a timed activity, which makes it easy to make a user mistake at one point or another to ‘approve’ the update just by pressing to (try to) get on with the activity.

    If you didn't want that, then you should have selected Dismiss. The firmware update file has already been uploaded to your watch, but at least you'd have to take the initiative to dig through the watch's menu tree to start the update.


    Perhaps, but I absolutely categorically pressed 'remind me' again, and much to my surprise it reset and started installing.

    Getting quite sick of Garmin now, they deserve to go out of business for a) the continual cock-ups and b) the complete lack of acknowledgment of any issues on here, the rediculously slow fixes to problems they do introduce and the continued arrogance of not allowing people to downgrade after their repeated cock-ups.

    They need reminding that this isn't some piece of cheap tat from Ebay China, its a premium product that is now 9+ months old and it is still completely unreliable and becoming worse with each release, with sleep tracking that doesn't work, and 24/7 HRM that is nowhere near 24/7 (even though it was when it was first released) .
  • Wiped my sideloaded watchface after the next time I charged after updating, and now it won't show it in the options list to put back.
    Even if I try to put the face back, it deletes the .PRG file right after I unplug it from usb.

    Look in \garmin\apps\log\ciq_log.txt on the watch. You probably have a "signing" error (new with the 1.3 VM). You need to build your sideloads with the 2.1.x SDK to get proper signing....

  • It won't even sign anything I compile with 2.1.x, it just gives me an error about not having a key....
    Nevermind, after searching forums found the answer to that one about generating a developer key in connect iq settings.

    I don't recall if it's mentioned, but once you upload something signed with your key to the app store, you need to have the same key when you update it, so make sure you save off your key in a safe place (maybe a cloud of some sort)! (it's so someone that DOESN't have your key can't replace something you have in the app store with a version that could be doing things you don't want!)
  • *nevermind, solved that. The 2.1.x connect iq SDK is not the same as the 2.1.x eclipse SDK update.... really wish that was pointed out better.

    Thanks for the pointer Jim - i hadn't check in recently on the dev side of things so I was way behind.

    I'm not in a position to try and reproduce the issue, since I've already updated the firmware on my FR235 to v5.20, but others who are reading this thread ahead of updating may be able to do so and confirm whether it happens to them too or just you.

    Here's hoping that someone will try.

    Getting quite sick of Garmin now, they deserve to go out of business
    Whether Garmin goes out of business ultimately depends on the decisions of a broad consumer base. If its product management and/or marketing teams manage to convince people to keep buying at the asking prices, then it deserves not only to remain in business but become more profitable, since that is what commercial enterprise (as opposed to service to the user community) is all about. Arrogance and/or lack of responsiveness may be offputting to some consumers, but in this day and age of ready information availability (or is that overload?), there will always be more consumers who are ready to commit to purchases on the basis of on-paper feature sets and technical specifications of a product if the price is affordable/competitive.
