Client for Garmin watches

[fabrikant]

I have developed a client for Garmin watches . Anyone can use it for free.
Unfortunately, the client works using an intermediate server. I explained the reasons here
I hope that future API changes will allow me to abandon the intermediate server. Then I will rewrite the client to work independently from the intermediate server and publish the source code.

Hello and first of all thank you for creating this application!

I set everything up, created a playlist.

My server is running via nginx proxy with lets encrypt certificates. I tried API token and username with password, but during sync it always stays at 0% and doesn't retrieve any data.

Any ideas?

thanks

You should do the following steps

1. Create a playlist on the ABS server and add books to it
2. Select the created playlist on the Garmin device.
3. Start synchronization
4. Be patient. The percentage increases while downloading media files. But before that, the list of books, the list of files, and covers are downloaded. If the playlist is large, then 0% may be displayed for a long time.

If synchronization still does not work, look at the "Books on the server" list on the Garmin device. Are there any books there? If you tell me the URL of your server, I will check the logs for errors.

Thanks for the feedback. I've now selected the playlist, and now It start to download. Thnx

Is it normal that the download takes so long?

I downloaded a book that was about 800 Mb and it took about 45 minutes.

My upload speed is 30 Mbit/s, so the 800 Mb should be downloaded in a maximum of 5 minutes?

Yes, it is normal
Garmin devices are really slow on wifi.

I can't optimize anything. All media is downloaded from your server. No intermediate server is used to download media. A third party developer like me does not have access to the network stack.

I recommend:

1. Sync while charging your Garmin
2. Keep your Garmin as close to your router as possible
3. Scan nearby access points and select the freest channel on your router. The watch can only work on 2.4 GHz
4. If your ABS server and watch are on the same local network, you can set up routes on your router so that traffic does not go outside

In any case, you will not be able to get high speeds when syncing your Garmin watch. In my opinion, the best case scenario is syncing while charging. And yes, syncing starts automatically while charging.
