After having this in my private branch for a few years, I’m submitting a slightly cleaned-up version for a PR. This PR adds support for Garmin Vivomove HR (issue #959). I’ve used it as a daily driver for the whole time and it seemed to work fine for me, so unless I broke something during the rebase & cleanup, it should be fairly tested, FWIW. Implemented features: - basic connectivity: time sync, battery status, HW/FW version info - real-time activity tracking - fitness data sync - find the device, find the phone - factory reset Features implemented but not working: - notifications: fully implemented, seem to communicate correctly, but not shown on watch Features implemented partially (not expected to work now): - weather information (and in future possibly weather alerts) - music info - firmware update: only the initial file upload implemented, not used Things to improve/change/discuss: - Device name hardcoded in `VivomoveHrCoordinator.getSupportedType`, service UUIDs not available at the time (this is a general limitation of GB, I guess?). - Download FIT file storage: Should be store (and offer the user to export?) the FIT data forever? - Obviously, various code improvements, further cleanup, etc.
