This is what I get after disabling all systemd GPS-related units and 
using the above procedures:

gpsd -nND 8 /dev/ttyUSB0

If I do:

gpsmon

I get:

tcp://localhost:2947          JSON slave driver>
(82) 
{"class":"VERSION","release":"3.16","rev":"3.16","proto_major":3,"proto_minor":11}
(32) {"class":"DEVICES","devices":[]}
(122) 
{"class":"WATCH","enable":true,"json":false,"nmea":false,"raw":2,"scaled":false,"timing":false,"split24":false,"pps":true}


But nothing else shows up. I.e., no nmea messages, etc.

Opencpn, qgis, etc. cannot access the gps.


I've checked that gpsd is using the port:

lsof -Pnl +M -i4
gpsd       9754       99    3u  IPv4 1039353      0t0  TCP 
127.0.0.1:2947 (LISTEN)

lsof -Pnl +M -i6
gpsd      9754       99    4u  IPv6 1039354      0t0  TCP [::1]:2947 
(LISTEN)


I'm sure I'm missing something...

Any hints?

Thanks for your help.

All the best:

Pedro
