Also after reading your discussion with Howard I understand:
OnStep and OnStepX behave differently (which we already did know but it is worse that I suspected
Timeouts in SWS will not be changed soon
Rotator is not yet mature and we should only use :GX98# expectin R#, D#, N#

and if I understand well SWS changes the behavior of OnStep so that rA# FA# return not the same as with USB

@Khalid,

Go the SWS Working, not exactly true :-)

I can connect my PC to SMW but my phone ( and I tried with three other Android) still does not want to connect.
I don't know if I am alone in this case but since I never use it ...

Differences USB / SWS
It is clear that SWS does something different than OnStep over USB.
thr first ":r" command hangs for 120s

Why I don't know but this is for sure one point to investigate.

Most probably will not survive today :-)

Now I cannot connect anymore to the SWS ....
I tried to enable access point mode to join my router to make further tests and nothing.
ESSID appears and disappears ...

James,

I think we have a solution that will probably make everything work as it did before SWS.

Basically rotator detection has to be with:
:GX98#
And waiting for at least 250 ms for a reply.

And if it returns N# there is no rotator and no more polling for it should be done.

Let me know when you have a fix, and I will test it.

Khalid,

I tested the modification, it seems to work.
See attached file

I will do some tests but so far no timeouts

Except the :GX03# that reports 1 s ?????

Success!
No more timeouts ...

Some comments before we get this in Jasem's PPA ...

I noticed that this line is no longer there. Is that intentional?
- FI::updateProperties();
For curiosity's sake, I added it back, recompiled, and tested. Works well.

There are also these warnings:
Don't know if we care or not.

drivers/telescope/lx200_OnStep.cpp:549:23: warning: comparison with string literal results in unspecified behavior [-Waddress]
if (response=="R" | response=="D")
^~~
drivers/telescope/lx200_OnStep.cpp:549:39: warning: comparison with string literal results in unspecified behavior [-Waddress]
if (response=="R" | response=="D")
^~~
drivers/telescope/lx200_OnStep.cpp:549:21: warning: suggest parentheses around comparison in operand of ‘|’ [-Wparentheses]
if (response=="R" | response=="D")

Finally, can you please remove this commented out line, for clarity?
+ //if (!sendOnStepCommand(":rG#")) // do we have a Rotator 1

FI::updateProperties(); still there on line 539 ????
Which line are you missing?

Of course it needs cleanup before issuing a pull request

It was removed by Jame's recent PR, and it is already in Jasem's.

See this

github.com/indilib/indi/pull/1569/files

And INDI works for me over WiFi with SWS with and without that line there.

So we are good here.

@Khalid, @James
the warnings are compiler flags dependent but anyhow I changed the way to compare to be consistent within the code.

I was not aware about the last commit so re-included the FI::updatyeProperties

but to submit a pull request we need to update also the header file and drivers.xml

so last attachment.

I leave up to James to do the pull request if he don"t mind

Tested it again, and it works great!

How about changing the response checking to be:

if (response[0] == 'R' || response[0] == 'D')

That is faster than strstr, and less error prone.

Just for info,

here is how I dis test a set-up and found it working well.
I did not test from a Windows PC but it should work too.
