I have emailed you off list with an example from one of my projects which works with GPSD 3.15 through 3.24 which you may find helpful.

I can't see how that ever worked.  Your program does not check
if the receiver JSON has the data you are trying to read.

Take a look at example.c for ideas on what is missing.


I could not find "example.c" for gpsd.

It is in the git repo, in the tar ball, in the libgps man page, ion
the web page,  etc.

Since you don't know how to grep or search:

I did find gpssnmp.c and a compiled version, which appears to be a
tidied up version of the software I submitted some time back, for
which, thanks!

Yeah, bot used by many.

On running the compiled version, though, I get a "connection failed"

     pi@RasPi-22:~/gpsd/gpsd-3.24.1~dev/clients $ gpssnmp -g
. gpssnmp: ERROR: connection failed

Hmm, I see that.  I'll look at it.

WHile we are talking SNMP, I have been asked where those OIDs came from?



I didn't find example.c in the GIT download.  I've used "find..." before, but when I saw lib... I thought "that can't be the right file"...  Thanks for the example URL.

Thanks for checking out gpssnmp.c.  The only peculiar thing about this RPi is that ipV6 is disabled, but it was disabled on the previous 3.23 install.

The OIDs are invented by me.  If you can find better - more official - ones let's swap.
