Package: gpsd
Version: 2.92-1
Severity: normal
man gpsd claims that
"A TPV object is a time-position-velocity report. The "class" and
"mode" fields will reliably be present."
but I keep hitting TPV objects that do not include mode field at all.
I can reliably reproduce this by running
echo
'?WATCH={"class":"WATCH","enable":true,"json":false,"nmea":true,"raw":0,"scaled":false,"timing":false}'
| nc 0 gpsd
in one terminal and then running
#!/usr/bin/python
import gps
import sys
session = gps.gps()
session.stream(gps.WATCH_ENABLE | gps.WATCH_NEWSTYLE)
for report in session:
if report["class"] == "TPV":
if True:
keys = report.keys()
if "mode" not in keys:
print("bug, TPV report does not include mode!")
sys.exit(2)
if report["mode"] == 2 or report["mode"] == 3:
print("%s %s" % (report["lat"], report["lon"]))
sys.exit(0)
else:
sys.exit(1)
multiple times in a different terminal:
$ for i in 1 2 3 4 5; do gpsd-get-position ; done
60.16XXXXXXX 24.9XXXXXXXX
bug, TPV report does not include mode!
bug, TPV report does not include mode!
bug, TPV report does not include mode!
bug, TPV report does not include mode!
tcpdump shows
{"class":"TPV","tag":"GLL","device":"/dev/ttySAC1","time":1268500224.000,"ept":0.005,"lat":60.161XXXXXX,"lon":24.93XXXXXXX}
so this should bug should not be limited to the python bindings.
(The above python program "gpsd-get-position" works only if I also apply
