Isn't the result obvious? The only application you ever told about your bluetooth GPS is MM. And now you always have to start MM to enable to GPS. How should the framework or any other application start the GPS if only Maemo Mapper knows the required details like the BT MAC? Unless Maemo-Mapper also works with a blank MAC address setting as desciibed here for the internal GPS: https://garage.maemo.org/plugins/scm...gs_GPS_heading it probably won't work with anything but Maemo-Mapper. What's descibed there for the "internal GPS" applies to all GPS devices handled by the GPS framework. And only those work for gpxview as it only works with devices handled by the GPS framework. Summary: If you can leave the MAC address entry in MM blank, the GPS should also work for gpxview as this indicates that your GPS framework is setup properly. If you need to specify some mac address for the GPS to work within MM, then GPS in gpxview won't work since you are bypassing the GPS framework and make MM directly access the GPS. This isn't good ...
