Very nice device. I succeeded to connect the Bluetooth interface and it works (including exporting data to clipboard) Bluetooth connectivity seems to go down after a few minutes though when the screensaver goes dark. After disabling the screensaver (to zero minutes) seems to work for the last 10 minutes or so Thanks |
