Hello Mark,

Thanks for your reply. Here are my answers…

root@raspberrypi:/etc# systemctl start gpsd
root@raspberrypi:/etc# gpspipe -r

Then silence.

root@raspberrypi:/etc# killall gpsd
root@raspberrypi:~# cat /dev/serial0

… no output

I only have one Pi so I can’t test another. The one I have seems to run raspbian pretty well.

Due to operator failure with BBcodes, the dmesg output wasn’t listed in my original post (although it was there) so here it is again…
