Maybe due to the newly added datetime timezone info.

OBSERVED
json.loads() can fail on some (valid) output from GPSD

REPRODUCE
Add a NTRIP source to gpsd and it will emit all kind of (valid) data that is not handled correctly by gpsdclient.

CAUSE
GPSD can emit trailing commas in the json data. This will cause the standard python json parser to choke.

PROPOSED FIX
Use json5 or yaml functions to parse the data.

Hello,

I am getting an timeout error when running your source.

Do you know what may be causing this issue currently?

Hello,

I had an error of no connection at first. I restarted the gpsd.service and everything works just as stated. Thank you for making this lib. available.

It is working well so far. I got some help from a person on writing to files in your gpsdclient lib. It helps to keep files of specifics.

oh!

Are there any resources you know of currently for porting to .kml files for Google Earth views? I was going to power my device, take a couple miles out of my day to move around w/ the device, and then hopefully put them manually into a .kml file for viewing in Google Earth.

I think the .kml files need to have a specific way of being managed:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
<Document>
<Style id="yellowPoly">
<LineStyle>
<color>7f00ffff</color>
<width>4</width>
</LineStyle>
<PolyStyle>
<color>7f00ff00</color>
</PolyStyle>
</Style>
<Placemark><styleUrl>#yellowPoly</styleUrl>
<LineString>
<extrude>1</extrude>
<tesselate>1</tesselate>
<altitudeMode>absolute</altitudeMode>
<coordinates>
 
# Here are where the coordinates go in "LAT, LON" and etc.
 
</coordinates>
</LineString></Placemark>
 
</Document></kml>

I guess I could pipe the results of my .txt file to a .kml file at a particular section in the file.

Seth

P.S. Anyway, if you are good with Python3 and your lib, please let me know if you have an online resource for this particular method of promoting .txt to .kml to Google Earth. Sorry if this is off topic. It can be closed if it is too far off. Thank you.

Hello,
I'm trying to run the following script:

from gpsdclient import GPSDClient

client = GPSDClient(host="127.0.0.1")
for result in client.json_stream():
print(result)

But it gives me always the error

714             if source_address:
715                 sock.bind(source_address)
716             sock.connect(sa)
717             # Break explicitly a reference cycle
718             err = None

ConnectionRefusedError: [Errno 61] Connection refused

I try to change the host to '0.0.0.0' but still not working and I do not know how to solve it ???!!!
Any hints for that!!
