[gpsd-dev] ubxtool and remote gpsd

[Ken McGuire]

Hi Gary, et. al.

Just subscribed to this list, but I've been reading the archives for 
several months.

I have several test setups using u-blox F9P/T devices as well as some 
older M8Ns.

One is a datalogger running on an Orange Pi Zero with the F9P connected 
via USB. I'm using the latest gpsd 3.19~dev. I can run gpsd and connect 
to it locally with cgps as well as my own monitor code (based on cgps). 
Works fine. I can connect locally with ubxtool and it too works. I can 
also connect to it remotely with cgps and my monitor tool and both work 
as expected. However when I try connect remotely with ubxtool (ubxtool 
192.168.0.134) I get the following error:

ubxtool: failed to connect to gpsd [Errno 111] Connection refused.

Both <nc -zv 192.168.0.134 2940-2950> and <nmap 192.168.0.134 -p 2947>  
indicate that the port is open.

After a bit of poking and a few print statements in ubxtool and 
client.py I found that ubxtool is trying to connect to 127.0.0.1:2947 
and not 192168.0.134:2947 even with <ubxtool 192.168.0.134> as the 
command line.

At about line 6626 in ubxtool I change:

                self.ser = gps.gpscommon(host=None)

to:

                self.ser = gps.gpscommon(host=opts['target']['server'])

Which seems to solve the problem.

I am not a programmer but a hardware guy, so my solution may be all wet.

Hopefully you can get this fix or a more correct/complete/better one.... 
in before the 3.19 release.
