since Kstars is the client and it is up to the client to display properties it is likely the client that makes things like that.
This is why I use sometimes CDC to check if behavior is the same as in Kstars.
I just compiled Kstars Version 3.5.7 Beta Build: 2021-12-05T21:27:06Z and the bug is closed
It seems someone try to use Bluetooth as the main connection between OnStep and Computer.
Obviously it does not work correctly.
Does somebody use Bluetooth with success?
Have a look on this issue github.com/indilib/indi/issues/1579
Finally started trying to test this and as soon as the port is bound via rfcomm and thus properly setup as /dev/rfcommX (provided it's powered on) I can't seem to reproduce it on my bluetooth board. (Basically what the Instructable does.)
So I'm inclined to think it may be an OS level connection problem, but I'm not entirely sure that's the case.
In the past bluetooth has been finicky as heck. (So that's good for me, but bad for solving the problem unless the above was the problem?)
However, I have discovered: It does sometimes crash kstars if it's disconnected, I'm surprised by that, with all the fixes I did to prevent that, not sure why it would only show up on bluetooth. I'll need to look into that later. (ARGH! I realized I was testing an old branch, so I need to go back and check this again after some updates/rebuilds.)
