Have you tried gols on desktop ? Garmin on linux sucks... https://medium.com/@euri10/gols-garmin-on-linux-sucks-f1f065f7529a It can upload activities and daily monitor, no download. Possibles issues: You have to mount your watch on the phone (I don't know how to)/send fit files over bluetooth (I'm stil trying to pair the phone with my car )... I'm pretty sure ubports can run python scripts ( as gols is)... Once you solve the issues you are done qith tracking info. But, I don't know nothing about notifications. Salut!

I managed to order one from ebay, but unfortunately it's not the one. It's 9147C instead of 9146C. It was written for BQ M10 FHD. I guess there is a new one as well. I tried it nevertheless, but it's not the right one. It a bit to wide on one side. So for now, I'm without a media to test/use ubuntu touch If someone will find a spare connection cable, let me know. Until then I'll be a passive observer. Cheers
