Ok. I use gpsd: 3.17 (revision 3.17), and "gpsdecode < log.nmea" return depth too.
But command "?POOL;" don't return depth.

In the https://gpsd.gitlab.io/gpsd/gpsd_json.html#_poll says: "The POLL command requests data from the last-seen fixes on all active GPS devices." I treat this and the other described below as the POOL command will return the cached last value, not the last NMEA sentence.
Is that not right?
