Tom Tom Sports discontinuation

[kubagruszka]

I'm TomTom watch owner and by surprise I was informed this week that they decided to shutdown their MySports platform making their watches broken. I was looking for some replacement and came across this project but from the description I don't fully understand if it requires the MySports platform or it's completely offline ? If it will continue to work maybe worth to mention this in the README file for wider audience ? I'm interested to keep my watch working so happy to contribute if so.

Hi! Does work fine without MySports, just switched to ttwatch + Trainingpeaks solution last week.
My workflow: download activities using ttwatchd + config-file as .gpx files and import manually to Trainingpeaks. Other applications with import funcionality (e.g. GarminConnect,...) should work as well as you can specify the output file format. Does even work better than TomTom MySports imo --> saved my watch :)

@c-a-p-666 Sounds good, but what do you do about missing GPS data? #176

[ltguillaume]

There seeems to be a data url for the GPS data in the watch's configuration. ttwatch uses it to update the GPS data, so it will probably stop working.

[c-a-p-666]

Should be possible to identify - but even if it is hosted by tomtom it should be a generic service for all their devices, it would just make no sense to host a file specifically for the watch as this is standard GPS information.
Even if it would not update the watch is still usable, it would only take longer to sync with the sattelites if not used for a while.

Looks like generic tomtom service:

and

"Navigation device" should refer to the used chipset instead of products.

[ltguillaume]

If the files/urls are chipset-specific, I'd expect them to disappear for their watches eventually.

[jdugge]

The URLs are not chipset specific, but it appears that they are only used for the TomTom Sports products and thus will disappear at the end of September 2023. That's also what it says on the TomTom website: "As QuickGPS data will no longer be available it might take longer for your watch to obtain a GPS fix."

Currently, the QuickGPS files are hosted here:
http://gpsquickfix.services.tomtom.com/fitness/sifgps.f2p3enc.ee (3-day extended ephemeris)
http://gpsquickfix.services.tomtom.com/fitness/sifgps.f2p7enc.ee (7-day extended ephemeris)

I was wondering if perhaps @ryanbinns and @scubajorgen are in contact with regard to this, since they're basically trying to solve the same problem at the same time.

@ltguillaume No. I haven't had a TomTom watch for some years since mine died, so there's not a lot I can do other than merge pull requests. I can't do any testing.

@ltguillaume with #181 you can configure the QuickGPS url, "just" need to add it as a new config (as described in the readme).

Pull the repo and rebuild the project!
