I have installed gpsd and client and try to connect dongle BU353. When I run xgps I can see 8-9 satelites. In the line at the bottom of the page it says /dev/tty/USB0. So I guess that is where I should find it also in Opencpn
But I have tried /dev/ttyUSB0 to five, Networkgps and others. But I get no NMEA-signals.
I even turned off SELinux and made sure I belong to group Dialout.
I bought the BU353 dongle today after spending many hours to get my bluetooth GPS
working. Somehow I had it up and running for a few minutes but I was unable to repeat it.
It shouldn't be so difficult. Just follow instructions and it should work
