foxtrotgps finds gpsd but doesn’t read the gps. (I compiled the program with the maintainer’s help.) xgps doesn’t find the gps either.

The GPS is a Garmin gpscsx. System is AMD Ryzen.

Suggestions?

While I can understand a lot of what you post, I am a bit at loss at what the results of the udev rule is. Am I right that it should result in a device file created? Then where is that file and what is the name?

And you have really documented with many facts (I like that), but the statement “foxtrotgps finds gpsd but doesn’t read the gps. (I compiled the program with the maintainer’s help.) xgps doesn’t find the gps either.” is not accompanied by any prove. Aren’t there any messages (when starting from a terminal)?

Hi
Start gpsd from the command line and add some debug…

NOTE:You will need to add the application:geo repository, gpsd is too old in Leap 15.2…


gpsd -D 5 -N /dev/ttyUSB0

Did you edit the options and add the device?


 cat /etc/sysconfig/gpsd | grep GPSD_OPTIONS
GPSD_OPTIONS="/dev/ttyUSB0"

Are you using ipv6? If not you need to edit the gpsd.socket file…

Is this gps device a USB dongle?

Example;

Before trying the suggestions in the second reply, I figured I would reply to your before making any changes. Here is the output from Foxtrotgps when run from a console:


foxtrotgps
REPOLIST == NULL

(foxtrotgps:5297): Gtk-CRITICAL **: 17:07:56.572: IA__gtk_entry_set_text: assertion 'GTK_IS_ENTRY (entry)' failed

(foxtrotgps:5297): Gtk-CRITICAL **: 17:07:56.572: IA__gtk_entry_set_text: assertion 'GTK_IS_ENTRY (entry)' failed
connection to gpsd SUCCEEDED

The program works even though the message is ominous. You can see the gpsd is connected, but no data is conveyed because gpsd isn’t getting the data from the GPS. Foxtrotgps otherwise operates fine.It loads maps,pans,etc.

When running xgps, no error messages are produced. Here is what you see on a console:


xgps
xgps: host localhost port 2947

Localhost use should require no changes to the firewall.

I forgot to mention I was using the geo repo. My rev of gpsd is 3.22-lp152.125.4-x86_64. (I had to transcribe that is I can’t cut and past from yast). Here is the output from gpsd:


 gpsd -V

And here is the drivers list:

99 times out of 100 IPV6 messes up your system. However I saw the message that gpsd needs ipv6 so I enabled it.

The GPS60csx is a stand alone GPS, not a dongle. Every indication is GPSD can handle garmin’s proprietary format though I did put it in NEMA output as well with no change.

Here is my issue with your suggesting I assign the gps to ttyUSB0. I also have a GSM modem in the notebook. It uses ttyUSB0, ttyUSB1, ttyUSB2 and ttyUSB3. It would be
best to let the operating system assign the USB ports. That said, if I make the GPS be ttyUSB0, will the operating system pick different ports for the modem?

As an experiemt I plugged and unplugged the GPS several times. The GPS itself says “connected” then it indicates “disconnected.” Here is the dmesg:

The idVendor is what I selected in the rules.d for garmin.

As an experiment I will assigned ttyUSB4 to the default.

Hi
You need to let the onboard devices use allocated ports, so run the following commands it two different terminals as root user with the device unplugged, then plug it it, this should verify the rule is working, should also tell you what the usb device is;

Terminal 1;


udevadm monitor

Terminal 2;


journalctl -f

Above should show what is being allocated, if not then you will need to tweak your udev rule to allocate as required, eg ttyUSB4

Then, just run the gpsd command I indicated, no systemd yet, just to make sure it’s working.

If your not using ipv6, then yes, disable system wide and copy over /usr/lib/systemd/system/gpsd.* over to /etc/systemd/system and edit to remove the ipv6 line from gpsd.socket. Once over in /etc any system updates won’t override your changes.

Hi
Another thought, the USB cable your using is what you use in storage mode? It should be a serial interface…

Does the gpscsx mount? I have 2 Garmin GPS devices and both mount readily without further tinkering, e.g.:

So does that mean it is trying to use ttyUSB2? Clearly a conflict.

Double checking /dev shows no ttyUSB4 created.

And I forgot to have the daemon running as shown below.

And now I will start over again. GPS is unplugged and the daemon is running. I aborted the processes in the two windows, ran clear, then started them again.

window one:

Looks like it still wants to use USB2. The /etc/sysconfig rule is set for usb4, double checking:


cat gpsd
## Path:        Hardware/GPS
## Description: GPS Daemon

## Type:        yesno
## Default:     no
#
# Whether or not to start gpsd automatically on plugin event
#
GPSD_STARTBYUDEV="no"

## Type:        integer
## Default:     2947
#
# Use different port for the daemon
#
GPSD_PORT=

## Type:        string
## Default:     ""
#
# Further options to gpsd
#
#GPSD_OPTIONS=""
GPSD_OPTIONS="/dev/ttyUSB4"

Well this gives me something to investigate. From my previous reply with the daemon stopped I still couldn’t connect to /dev/ttyUSB4 so that is something to check out.

10

I am in the Garmin proprietary serial mode. I know the storage mode and I am not in it. But it was a useful question.

11

Well now we are getting somewhere. I did a journalctl>temp and then used vi to search for garmin:


linux-yxjo systemd-udevd[469]: Invalid rule /etc/udev/rules.d/51-garmin.rules:2: unknown key 'ATTRS(idVendor)'

This page says it should be ATTR not ATTRS:

12

Does mass storage mode work?

And to show gpsd was running when above was done:

Now to get rid of the error I documented in journalctl I had to change the rules.


 cat 51-garmin.rules 
#SYSFS{idVenor}=="091e", SYSFS{idProduct}=="0003", MODE="0666"
#SUBSYSTEM=="usb", ATTR(idVendor)=="091e", ATTRS{idProduct}=="0003", MODE="0666"
SUBSYSTEM=="usb", ATTR{vendor}=="091e", ATTR{product}=="0003", MODE="0666"
#SUBSYSTEM=="usb", ATTR{idVendor}=="091e", ATTRS{idProduct}=="0003" MODE="0666", GROUP="plugdev"

Note that idVendor wasn’t accepted. I went a web page on how to write udev rules and what is acceptable is “vendor” and “product”. I had to change the ATTRS to ATTR,

Change to the gpsd.socket:


cat gpsd.socket 
[Unit]
Description=GPS (Global Positioning System) Daemon Sockets

[Socket]
ListenStream=/run/gpsd.sock
#ListenStream=::1]:2947
ListenStream=127.0.0.1:2947
#ListenStream=0.0.0.0:2947
# To allow gpsd remote access, start gpsd with the -G option and
# uncomment the next two lines:
# ListenStream=::]:2947
# ListenStream=0.0.0.0:2947
SocketMode=0600
#BindIPv6Only=yes
BindIPv6Only=no

[Install]
WantedBy=sockets.target

OK now I will stop the daemon. Note the error regarding /dev/ttyUSB4:

Hi
It’s trying to connect as a storage device not a gps…

I see Speed 12 Mbit/s in the usb-devices output. So on the device it’s not in storage mode, your sure it doesn’t need a special cable and serial to connect as a gps device?

Hi
This is what I see when switching…

At this point I want to get NEMA working then work on mass storage. (Don’t tell anyone but I also have windows which I use in a pinch.)

Interesting since idVendor and idProduct weren’t accepted on my system but vendor and product were. Note the GPS60CSx is pretty old. It hasn’t seen a firmware update in a dozen years. I like it because it takes AA cells and is paid for, but mostly for AA cells.

If you could provide the rest of the associate files such as the rules it might help.

Hi
No modifications to the default install… no rules modified…

Perhaps a read here might help: USB Garmin on GNU/Linux - OpenStreetMap Wiki

My nuvi 260w is 12+ years old… I had it working years ago and pretty sure I used gpsbabel… I just use standalone gps device here along side the ads-b antenna, it goes nowhere :wink:

I see ModemManager blacklists garmin_gps /usr/lib/udev/rules.d/77-mm-usb-device-blacklist.rule

There is an optional serial cable but I never used it. It looks a lot like a cable I used on an Lowarance GPS decades ago. The manual is online. I would cut and paste the section regarding the USB port but Garmin in their wisdom decided to DRM the contents. Manual page 96. PDF page 106. Note the Garmin proprietary data format is only available on the USB port. That is there is a USB serial mode. I never used it in NEMA mode.

I put the GPS in storage mode for yucks and it locked up. Unfortunately my copy of the mapsource CD has failed, I need to find where I stashed the original to use mapsource.

Hi
I would then try the serial cable, does the system your using have a serial port, else need a serial to usb cable… DRM, that’s why I suspect the need to looking at gpsbabel…
