More NMEA data

[free-x]

Hi Andreas,

i'm using sometimes for personal purposing pynmea2 library (https://github.com/Knio/pynmea2)

For example:

#!/usr/bin/env python

import sys
import pynmea2

if len(sys.argv) < 2:
   f=sys.stdin
else:
   f = open(sys.argv[1])

for line in f:
  if line.startswith("!"):
    continue
  elif line.startswith("$"):
    msg = pynmea2.parse(line)
    if type(msg) is pynmea2.types.talker.RMC:
      print "RMC %s%s %s%s sog=%s cog=%s" % ( msg.lat,msg.lat_dir, msg.lon, msg.lon_dir, msg.spd_over_grnd, msg.true_course)
    elif type(msg) is pynmea2.types.talker.GGA:
      print "GPSFix at %s%s %s%s. Sat %s in use %d quality" % ( msg.lat,msg.lat_dir, msg.lon, msg.lon_dir, msg.num_sats, msg.gps_qual)
    elif type(msg) is pynmea2.types.talker.GLL:
      print "ValidStatusFix %s%s %s%s" % ( msg.lat,msg.lat_dir, msg.lon, msg.lon_dir)
    elif type(msg) is pynmea2.types.talker.VTG:
      print "SOG %f" % msg.spd_over_grnd_kts
    elif type(msg) is pynmea2.types.talker.DBT:
      print "Depth: %s" % msg.depth_meters
    elif type(msg) is pynmea2.types.talker.MWV:
      print "Wind: %s %s %s%s" % ( msg.reference, msg.wind_angle, msg.wind_speed, msg.wind_speed_units)

Would that way be helpful?

Looks promising. Thanks, I will try it out. Would like to go away from gpsd anyway...

With 20191223 the infrastrcuture is there. The plugin interface provides the functions. Documentation is still ongoing.
