I'm trying to develop apps for my Venu3 and I would like to test the app on real HW by copying the PRG file to the watch. I can do this with File Explorer but I'd really like to be able to do this from the command line. I notice that one of the Connectiq tools is 'shell' and there's an option to this command to push a file to the device. Unfortunately, I cannot get this command work, it always throws an invalid destination error and fails, e.g. the command 'shell push xyzzy.log' should push a file to the root directory of the device but it fails with invalid destination.
Does anyone know how to use this tool to push files to a Garmin device?
