I'm the other person, lol

There no meridian flip possible anymore with all the versions of Ekos/Indi after version 1.5.5 Stellarmate.
I tested all of them 1.6.0, 1.6.1, 1.6.2 and the beta 1.70 on fresh installed cards.

There is no HA countdown anymore in Ekos so meridian flip is never issued.
When arriving at target ekos reports the remaining HA time correct but then the counter stops and stays there.
Only old version 1.5.5 seems to work right.
Could this be an OnStep Indi driver issue?
Using the mount simulator all is working well.

Hi and happy new year to everybody.

I have tested the meridian flip issue and it seems that it is OnStep than stops tracking at meridian crossing even in standalone (using terminal)
there are threads about that here onstep.groups.io/g/main/topic/87662486?p...y,,,20,2,60,87662486

I will investigate more but I don't believe Indi is the cause here

Kstars Version 3.5.8 Beta
Indiserver INDI Library: 1.9.4
OnStep version 1.13
OnStep Firmware 4.24o

I think I managed to repair Meridian Flip
There is a typo in the firmware code, and submitted an issue to Howard.

Yes I see it too but it is what causes OnStep to stop tracking.
Wait until Howard looks at it.
For the time being I made many tests and the Meridian Flip works

After doing more testing if seems that there is no issue with OnStep but with indi_lx200_OnStep driver and most probably confusion on how Meridian Flip works.

In fact when we enter same values for Minutes Past Meridian East and West , Onsep considers there is no windows for Meridian Flip.
Lets say we enter 30 for both East and West OnStep will consider the limits overlap
........................M.......................30
If we enter East = 30 and West = -30 then OnStep sees a window between -30 and 30
-30........................M.......................30

So we need to modify Indi Driver so that we can enter these negative values

I tested with this modification and it seems working.

I will do some more tests before issuing a pull request.
For those impatients, I suggest doing the setup with Android App or Web Server

Another workaround is to set East and West to positive values but always West < East

My issue is related but not the same. Stellarmate 1.5.5 works as it should.
All versions after that show no HA counter counting down anymore and no matter what value i put in ekos.

Kstars 3.5.7 stable latest build
Indiserver don't know. Terminal command not found.

But all versions before won't work either accept 1.5.5 stellarmate, don't know the versions of Indi or Kstars from that one.
I can find out but not at home at the moment.

I have latest modification on github.com/azwing/indi
I made many tests with different set-ups and it works.
Would be nice if somebody could test before issuing a pull request.
