Hello Gary, Yup, works fine. I have several GR-601W (Navisis GPS/PPS over USB) running all the time Zero configuration needed. That is comforting. Now I just need to figure out
my problem. Be sure your gpsd is compiled with KPPS support. I have added timeservice. See prior email about compile issue. Is anything else [not default] that would be needed for KPPS? Also interesting is to send the list the first 40 lines of: # gpsd -D 5 -N -n /dev/pps0 /dev/ttyUSB0 |& fgrep PPS Here is that output…. root@ATIS-Box:/home/pi/gpsd-3.19# ./gpsd -D 5 -N -n /dev/pps0 /dev/ttyUSB0 |& fgrep PPS gpsd:PROG: PPS:/dev/ttyUSB0 chrony socket /var/run/chrony.ttyUSB0.sock doesn't exist gpsd:PROG: KPPS:/dev/ttyUSB0 checking /sys/devices/virtual/pps/pps0/path, /dev/ttyUSB0 gpsd:INFO: KPPS:/dev/ttyUSB0 RFC2783 path:/dev/pps0, fd is 6 gpsd:INFO: KPPS:/dev/ttyUSB0 pps_caps 0x1133 gpsd:INFO: KPPS:/dev/ttyUSB0 have PPS_CANWAIT gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS will be used gpsd:PROG: PPS:/dev/ttyUSB0 thread launched gpsd:INFO: PPS:/dev/ttyUSB0 ntpshm_link_activate: 1 gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:PROG: switch_driver(PPS) called... gpsd:PROG: selecting PPS driver... gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:WARN: PPS:/dev/ttyUSB0 unchanged state, ppsmonitor sleeps 10 gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:WARN: PPS:/dev/ttyUSB0 unchanged state, ppsmonitor sleeps 10 gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error gpsd:WARN: PPS:/dev/ttyUSB0 unchanged state, ppsmonitor sleeps 10 gpsd:INFO: KPPS:/dev/ttyUSB0 kernel PPS timeout unknown error Regards, Neal |
