Here is where the problem is.

The time stamps tells the story ...

12:55:59.364911 indi:43846 -> onstep:9997 :rG#
12:55:59.584761 onstep:9997 -> indi:43846 0

12:56:05.084834 onstep:9997 -> indi:43846 0
12:56:10.086962 indi:43846 -> onstep:9997 :rT#
12:56:10.518762 indi:43846 -> onstep:9997 :rT#
12:56:10.520447 onstep:9997 -> indi:43846 0
12:56:15.522832 indi:43846 -> onstep:9997 :rb#
12:56:15.888708 onstep:9997 -> indi:43846 0

It takes 5 seconds for most of the :rX commands, but not all of them.

James,

Here is more info on the problem, while I am compiling your fix.

One possible issue is that the first rotator command (rG) returns immediately, so INDI thinks we do have a rotator:

2021-11-14T19:05:39: [INFO] Rotator found.

But then all the following :rX commands take 5 seconds.

Will let you know when I test your branch.

Yes,
really strange
the 5 sec time is not between command issue and response but between response and the next command

and more strange is I see only :rG# once and then no subsequent :r commands

Perhaps you don't see them because the detection works properly, and finds that there is no rotator. In my case, with what is in Jasem's PPA, I think what is happening is that detection thinks there is a rotator, then all its commands are issued, and it times out.

I build James's branch that he linked to. INDI LX200 OnStep does not connect over WiFi at all. I changed 0.1 second to 0.4 seconds to give it time, but it still does not connect at all. Also 0.8 seconds does not work.

Downloaded James' fork, with branch master, and it does not connect either.

So there is a discrepancy between what James has and what in Jasem's PPA packages that prevents INDI from working over WiFi completely.

  Khalid,yes it is exactly what I suspect strongly. (I lose my Latin :-)We have for sure different OnStep Versions, I don't see another explanation.I added my source ( github.com/indilib/indi ) so you can make a diff 

The versions I tested were:

- Latest from Jasem's PPA -> botched device detection leading to lots of timeouts.

- James Lancaster's branch linked above -> INDI does not connect over WiFi at all.

- With James' branch, but replacing the two files with yours, I can connect, but there are still the same issues that I see with Jasem's PPA:

Wrong values return because of timeouts.

That makes me crazy too.
It is completely different in my case.

Here is something crazier

See this image i.imgur.com/vC2TX60.png

This is as I start INDI, and the mount is actually at home, and not slewing nor tracking at all.

Currently my branches are

As I just looked the PR JUST got merged, so
ppa = old indi master
my master == indi-master (was also 2021-fix-focuser-not-hidden)
network-timeouts == master + network/detection fixes

The network timeouts also includes the not succeeding on failure that seems to be your problem Khalid. It should have the line either: Non-Network based connection, detection timeouts set to 0.1 seconds or Network based connection, detection timeouts set to 2 seconds If neither shows, it's not the right branch.

That should override if you are on the right branch. I am away from my telescope at the moment to test, but I'll see about it when I can. If you see the ONSTEP_TIMEOUT_SECONDS & MICROSECONDS at the top of lx200_Onstep.cpp, it's the wrong branch.

(Apologies if I'm being confusing or am confused myself, I got little sleep last night and unfortunately it's not due to using telescopes.) I'd assumed it was through the SHC/ESP32 on that.

For this what version were you on? X?

Aha, Yep. :rG# gets defined even if no focuser(aka no timeout) :rA# = 0 is no rotator, and :rA# = 1 rotator,

Psudocode logic for later:
if OSVersion == $ONSTEPX
if getSingleCharResponse :rA == 1
rotator1 = true
else
if (no timeout) :rG
rotator1 = true

Yes I have OnStepX installed.
But With OnStep 4 I had also no issue
