@Blueshawk and Avarakin

Thanks for the more precise description.
I really need to speed-up my setup to start testing in real situation.

I will make a trial with my EQ6-R mount and EQmod driver, could be interesting.

Did anyone diagnose what the source for the precision slew never ending problem is? Or at least what conditions trigger it?

For example: Could it be when the backlash compensation setting is more than the required precision?

I have seen it several times, but can't seem to get a pattern of when it would happen.

Khalid,

seems the season is not good for testing :(

Unfortunately more patience is needed on my side before I can start serious testing in rteal conditions.
Most probably begining November if the weather play whith.

Some more patience, I'm sorry

So far I haven't found it. Though I give my mount a bit to settle (I have a bit of backlash which I haven't taken the time to properly setup. So that could be a possibility...)

Also, can you check if it's got Pulse Guiding set to ON (Main tab, I think)


I just pushed some changes to enable the outputs, and hopefully satellite tracking (Not 100% sure that it will work yet.) to azwing.

I've only been able to get outside one time when it wasn't cloudy, so I haven't been able to test, unfortunately.

There's also this checksumming which I think is good. Might resolve some problems, but does mean that we'll have to re-implement some of the LX200 stuff (or we could restrict that to just things like guiding/moving and see if that resolves the issues?

Quoting Howard on the list:

I have 'Use Pulse Cmd' set to On, which is I think is the default, since I did not mess with it, nor use the ST4 port in anyway.

Yes, I think this requires reimplementing everything. So it is a parallel set of commands with the same functionality, but return codes on some that have no return codes in the LX200.

It can be implemented with some effort, but it may be the case that the OnStep telescope driver in INDI to be totally separate from the underlying LX200 class, with everything implemented with the new command set.

Also, it means that OnStep users have to use Alpha only?

I should also mention that I did one precision slew tonight (it is clear, but with a bright moon), and it worked without a problem. It does not happen in every case. Not sure what triggers it.

By the end of the night (3:15 am or so), all the precision slews (about a handful) were all successful. No hangs. I set the precision to 30 arc seconds.

Hi ,
sorry not to mention how the combination works.
I must say the driver works perfectly. I can use the focuser, too by simply putting the onstep driver name in the setup configuration.
What i am missing at the moment, is something where I can set the actual position of the focuser, without moving the focuser.

From my experiences of the last months, I completely switch over to libindi.

Except my big fat mount. It is controlled by the sitech servo II controller. Here i will encapsulate the win7 instance in a qemu image running on my barbone.

Regards,
Gerrit

Hi there,
I would like to ask, can the Indi driver for the Onstep work through Wifi?
I am able to connect to the Onstep controller through both Wifi and /dev/ttyACM0, but slewing, guiding etc only work when connected to /dev/ttyACM0.

I am however able to connect to the mount from the Android app, SkySafari and Sky Planetarium and all of them are able to control the mount through Wifi.
Am I missing something out or is the driver not designed for Wifi connections?
Thanks!

Using the latest PPA (indi-bin 1.7.5~201811141157~ubuntu16.04.1), there is a problem in converting internal float to sexagesimal format.

OnStep refuses to recognize :60 as a valid value. It has to be 00 to 59 only. Therefore, OnStep returns an error and refuses to slew to the target.

Here are log excerpts.

First for a failed conversion:
2018-11-21T13:15:35 EST ISD:Telescope sending coords RA: "11h 49m 59s" ( 11.8333 ) DE: " 14° 28' 02\"" ( 14.4673 )
2018-11-21T13:15:35 EST LX200 OnStep : "[SCOPE] <setObjectRA> "
2018-11-21T13:15:35 EST LX200 OnStep : "[SCOPE] CMD <:Sr 11:49:60#> "

2018-11-21T13:15:35 EST LX200 OnStep : "Error setting RA/DEC. "

Then for a conversion that works.
2018-11-21T13:27:55 EST ISD:Telescope sending coords RA: "11h 49m 35s" ( 11.8264 ) DE: " 14° 10' 47\"" ( 14.1798 )

Hi,

if you try to connect to the ESP web server it will not work.
To have WiFi working you must have the serial from OnStep over IP with ser2net for example, not via the WiFi as implemented in OnStep

example:
OnSter Serial 1 <==> Raspberry <==> ser2net <==> Wifi <==> your PC

Khalid,

this is strange. The conversion is done using Indi internal routines not specific to OnStep driver.
Of course havinb 60 is not OK.
May be something chganges recently in Indi I don't know.
How did you do to have this error?
Because when I enter the target manually it also does not accept the 60
