I bought a Garmin Forerunner 255 watch that I want to use only with Gadgetbridge. There is an old software version on the watch and I want to update it and I don’t want to connect it with Garmin Connect or Garmin Express app?

I have looked for the possibility to do an “offline” update but have not found it. Maybe the community will help?

    You’ll need to find someone sharing the gupdate.gcd file for firmware 21.22. You can drag and drop those onto the watches storage.

    Alternatively, use the desktop app to install ovwr USB?

      The latest version is 22.24 but I can’t find it anywhere gupdate.gcd file. As I wrote I don’t want to use the Garmin Express app.

        Gotcha! Another approach could be to set up the watch for a guest wifi / vpn routed access point?

        That’s what I do with mine. It means I can use the Garmin website for stats, get updates, sync / plan routes - but not have it connected to my phone, only connect to specific wifi when I allow, and only use data I agree to with Garmin’s variois policies.

        Obviously I dont get any notifications from my phone / weather, but that’s not something I care for.

    Just use the regular Garmin account and Bluetooth to your phone every 2 weeks to sync for health data use storage scopes and permissions to stop unwanted data collection, use privacy settings in the app, fake account. Be done. Never use support they will dox you.

        Permissions stop what the app can and cannot access in your phone, and storage access allows what the Garmin app can and cannot access in storage of data. Keeps your app more private with the added benefit of perhaps running leaner on your device.

      I know the project and keep my fingers crossed for it, but they currently support very old watch models that are not sporty.

    Just curious, what features work and what do you have to miss out on by foregoing Garmin connect? On their website Garmin devices are generally listed as partially supported, and I’m not sure what that entails.

          I’ve just spent the last week with Gadgetbridge for my Forerunner 265.

          Previously I had Garmin Connect installed on a separate Android user profile with Google Play Services enabled (GrapheneOS). I would only go in there once a week or so and look at the Garmin info as it synced over.

          Gadgetbridge is working pretty well - the great majority of everything I actually cared about viewing is accessible. I also have an always on BT connection for notifications and music controls which I was missing out on before.

          That said, there are a few drawbacks

          • Garmin presents the date better.

          Gadgetbridge often uses bar charts for time-series data where Garmin uses a line chart. e.g. Stress is a series of 1px thin vertical lines with colour to indicate bands. Garmin’s single line which swaps colour is far clearer.

          • GPS data is not overlaid on a map

          Its easy enough to open the GPX file in an external map viewer, but you can’t see its alongside heart rate etc and the track won’t be heatmapped for speed as in Garmin.

          Personally, I’m willing to live with these compromises for the privacy, certainly for another few months trial.

          As it seems easy to setup a regular export of Gadgetbridge data, I might make it a coding project to implement better visualisations in Python.

            Thank you for your feedback. It has reassured me that I am heading in the right direction.

            As it seems easy to setup a regular export of Gadgetbridge data, I might make it a coding project to implement better visualisations in Python.

            Will you make this project available to the public?
