- communication protocols - device support implementation - download FIT file storage 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: - Device name hardcoded in `VivomoveHrCoordinator.getSupportedType`, service UUIDs not available - Download FIT file storage: Should be store (and offer the user to export?) the FIT data forever? - Obviously, various code improvements, cleanup, etc.
