Expected Behaviour:

I have a NexStar compatible telescop controler which can conect at Stelarium throught Bluetooth on my celularphone an works prety well. I expect to do the same on Stelarium 1.1 or 1.2 on Windows 10 ( the controler was working ok with somme old version of stelarium on a Lenovo YOGA Laptop Windows 10)

Actual Behaviour

I get in the log file: "ERROR creating TelescopeClientDirectNexStar: cannot open serial device "COM5"
TelescopeClient::create(): Unable to create a telescope client."

I can tell you that if I connect on COM 5 with Putty and send some comands to the controler i receive good answers ( so the BT connection via COM 5 is working).

Steps to reproduce

System

  • Stellarium version: <stellarium-1.2-qt6-win64?>
  • Operating system: <Windows 10 Version 22H2>
    *Laptop ASUS ExpertBook

Logfile

If possible, attach the logfile log.txt from your user data directory. Look into the Guide for its location.

We just had a similar report (#2924) about COM port issues. Can you try the Qt5-based build (available tomorrow)?

Dear all

Happy new year and best wishes!

Regarding this issue i've installed the Stellarium QT6 1.22 on 2 differents Windows PCs and it chrashes when the telescope control is opened with the EQMOD driver after few seconds or few minutes. It's ok with QT5 version.

Thanks a lot

Hello everybody. I'm experiencing the same identical issue with an Orion (Skywatcher) Synscan V5 hand controller. Until i used stellarium version 0.xx everything was working fine. Since 1.0 version i get always "stopped" status and cannot control my mount. Currently i'm using version 1.2.5 qt6, but the plugin still not working.

Thanks a lot for opening this issue!

If you see the other reports on this, please conclude that trying Qt5-based 1.2 (0.22.5) is your best option currently.

Thank you for the advice . It's ok Qt5-based 1.2 (0.22.5)
I'm ok to test any Qt6 version.

Thanks a lot

I can also confirm, that win 32 bit Qt5 version works, win 64bit version doesn't.
Building stellarium from source is beyond my skills. Checking the SerialPort.cpp I would expect some of these messages in the log, but I don't see any; only the message from Lx200Connection::Lx200Connection functions. Maybe it helps.

I noticed some time ago that the Qt6 release broke the serial port connection to my SkyWatcher AZ-GTiX mount. I came here (to GH) and saw a number of open issues (this being one and #3006 being the other, already assigned to @TonyBhargav).

So I decided to look further only to find my dev system unable to build Stellarium since moving to Qt6. After that I found that the ASCOM driver worked fine so I parked it there and did no further investigation.

Roll on to today and I saw in the release announcement that the Telescope Plugin was still suffering issues and an appeal for help. So I returned to my dev system and now managed to get a GH/master build working so I can start to look into the issues around the dysfunctional serial port issue. I saw the appeal was potentially offering a reward. I am already a contributor to Stellarium, I expect no reward if successful, it's not required.

It maybe a good idea to consolidate all the issues that appear to be connected to Qt6 serial port issues as they're all likely to have the same fix when found.

@gzotti @alex-w if you want to assign this to me that's fine. --Andy

Yes, sure, please go ahead. I have no hardware and no time these months to deal with this, unfortunately. It needs motivation like an own non-working instrument to fix that :-)
