My Raspberry Pi 3 has been working fine for sometime with OpenPlotter. My GPS is a GlobalSat BU-353 on a USB Lead. My Pi clock is currently set by Internet BUT I will loose my Internet connection when I set of for some time. In OpenPlotter settings I ticked "Set Time from NMEA" and added the port details under "NMEA" > Name: gps Type: Serial Port: /dev/ttyUSB0 etc > apply changes > re-start (Kplex). Now with no Internet connection and Pi shut down for say 20 mins, my clock is 20 mins slow at start up but a few moments after OpenPlotter has played the "Ding Dong", my clock corrects itself precisely.
BUT the GPS data is now intermittent in OpenCPN. The three green signal strength bars keep coming and going and the data stream shown in the NMEA Debug window keep stopping anything up to 10 seconds or so at a time. My "Ship" icon changes from red to black and jumps about a bit.
as soon as I remove the entry for the GPS in OpenPlotter NMEA Settings window, everything is back to normal. Is there a way that I can fix this.
Many thanks
