Re: [gpsd-users] How to use ubxtool with gpsd

[John Klug]

The pps is specified because we have two pps devices (and sometime six or more 
tty).

As far as -F is concerned on the gpsd command line, I see that it is meant to 
allow a change of the gps device.  So is it non-functional when the devices are 
specified on the command line?  I verified that the device is actually created. 
 I suppose it could be used in the remote case that somebody connects a GPS to 
another serial line.

Sorry I was mixed up on the gps device parameter for ubxtool.  I found that if 
I use the correct serial port, ubxtool does work:

ubxtool -p PMS 127.0.0.1:2947:/dev/ttyXRUSB2
  ...

UBX-CFG-PMS:
 version: 0 powerSetupValue: 2 period: 128 onTime: 0x10 reserved1[0 0]
   powerSetupValue: Full power
...

Thanks

Why do you need to specify the /dev/pps0?  Why do you use gpsd.sock AND
the tty?

Hmm, I guess is should default the first device, you have at least two.

New tool, still kinks to work out.

Use gpspipe to see what devices you have.  Clearly not that one.
You have a ttyXRUSB0 and a ttyXRUSB2?  You use both above.

# gpspipe -w -n 20 | fgrep DEVICE
{"class":"DEVICES","devices":[{"class":"DEVICE","path":"/dev/ttyACM0","driver":"u-blox","subtype":"SW
