@Jamie, NMEA data probably relates to GPS data. Do you mean location data is supplied by the cell and wifi network and published by mnld? I have that switched off BTW, only using location data from the GPS. Updated yesterday to Arale OTA7 (that is 15.04 r6). Forgot to mention earlier that the following command are over the wifi connection. Repeating the nmap from #1 the port is now closed. The mnld daemon is still running but that might be correct if that is supplying GPS information to other internal processes, although it's not listening to a port any more. Still, GPS is working, as confirmed by the SensorStatus app (found support backend, method Satelite, location found) and working Google Maps and HERE Maps. So, works for me with the latest update. # nmap -sV -v ubuntu-phablet Starting Nmap 6.47 ( http://nmap.org ) at 2015-10-20 23:38 CEST NSE: Loaded 29 scripts for scanning.
