| Hello and good afternoon!
Thank you for your suggestion. I attempted but it didn’t work. May I ask am I supposed to be in a certain file before attempting this such as gpsd/gpsd? I found however the etc default gpsd file which I understand works under systemd. Despite this may I ask if I’m supposed to use the udev rules then?
I’m running into an issue attempting to run cgps as well. I have to use the command python3 cgps to run any programs but this error keeps appearing:
File “cgps”, line 1 SyntaxError: Non-UTF-8 code starting with ‘\xa0’ in file cgps on line 2, but no encoding declared; see http:\\python.org/dev/peps/pep-0263/ for details.
I found in the build.adoc that this is an error that may occur due to Python3 but it suggested that I use the command ln -s /usr/bin/python3 /usr/bin/python. However another error appears: ln: failed to create symbolic link ‘ /usr/bin/python’: File exists
May I ask for suggestions on how to get cgps to work?
Thank you for your time and consideration. Sincerely, Leon

May I ask how I set up the path for gpsd to connect to a USB GPS? I have downloaded version 3.22, but I'm unsure how to set up the DEVICES:"/dev/ttyACM1" command. While I was gpsd version 3.17 I could use sudo nano /etc/default/gpsd to set up the path, but for this version I'm don't know where to find this. May I
I know I need to use udev rules (my gps is a u-blox 8 of the port ttyACM0) so the commands in the files pi@clover-4865:~/gpsd $ nano gpsd.rules.in seem to do this, but do I need to replace gps%n with a value?
# u-blox AG, u-blox 8 (tested with GNSS Evaluation Kit EKV-M8N) [linux module: cdc_acm] ATTRS{idVendor}=="1546", ATTRS{idProduct}=="01a8", SYMLINK+="gps%n", @UDEVCOMMAND@
Do I go into gpsd.hotplug and change the devname to ttyACM0 or the new gps%n from above?
if [ "$ACTION" = "remove" ] ; then
if echo $DEVLINKS | grep -q /dev/gps; then
:
else
exit 0
fi
fi
logger -t "gpsd.hotplug" -p daemon.info "$ACTION" "$DEVNAME"
if [ -z "$DEVNAME" ]
then
logger -t gpsd.hotplug -p daemon.err "no device"
exit 0
fi
Or is it in pi@clover-4865:~/gpsd/gpsd-3.22.1~dev/clients/gps $ nano gps.py.in? Should I be editing the following commands below that are present in the gps.py.in file?
if self.gpsd_device is not None:
# add in the requested device
data_out = (b'?DEVICE={"path":"' +
polybytes(self.gpsd_device) + b'",')
else:
data_out = b'?DEVICE={'
# elif self.data.get("class") == "DEVICES":
# TODO: handle class DEVICES # pylint: disable=fixme
If I could I would like to ask how to set up this path because I would like to later experiment with a few other paths to test if I can connect to my flight controller. Thank you for your time and consideration.

Easy to capture your own.

You can capture anything that gpsd sends to JSON.

$ gpscsv --class SAT -n 2
