Yup.  I can easily get 1 cm accuracy with PPP.

Ah. Good.  The sample F9T board I have from Clive works great for me.

It always in the dark corners that the dust collects.  So keep at it.

That all, except setp 5/6 looks good to me.

I can no duplicate this with git head.  I can do both of these:
        ./ubxtool [ipv4]
        ./ubxtool [hostname]

So either your git is slighlty older than mine, or something we need to
find and fix.

That code was changed by:

commit e00c2bd65d95bd8d71077fa9147cdfd6b07504fd
Date:   Thu Jun 27 19:51:59 2019 -0700

So any test earlier than Friday is stale data.

Which should be a NOP, except it breaks the port selection.

Odd.  I do not see how the before Friday code would have done that.

Doubly odd.  Can you confirm your UBXOPTS environment variable is
empty?

I agree, except I can't duplicate, nor do I see how the code before
the recent fix could fail that way.

What is your Python version?
