Hi together, I hope, someone can help me with my problem:
(I use: Linux Mint 19.1, Intel x86, PyIndi)

I have two SBig CCDs: a STXL-6303 and a STF-8300. One should be at a spectrograph and the other one is for guiding.
How do I set up the indiserver properly, so that I can speak to both? I tried to use:
mkfifo /tmp/indififo
indiserver -p 7624 -v -f /tmp/indififo &
echo start indi_sbig_ccd -n \"STF-8300\" > /tmp/indififo
echo start indi_sbig_ccd -n \"STXL-6303\" > /tmp/indififo
and then connect to the indiserver using python and pyindi:
spec_indiclient.setServer("localhost", 7624)
gd_indiclient.setServer("localhost", 7624)
dev_spec = spec_indiclient.getDevice("STF-8300")
dev_gd = gd_indiclient.getDevice("STXL-6303")
spec_connect = dev_spec.getSwitch("CONNECTION")
gd_connect = dev_gd.getSwitch("CONNECTION")

But this let me connect only to the first camera. Even when I first try connect to the STXL, the connection is made to the STF.
The output on the console is:

new device STXL-6303


and the second time I don't get the connection switch.

With KStars and Ekos I can connect to both, if I select port USB1 for the STF and port USB2 for the STXL.

So, how can I tell the indiclient/server, that it shall connect to the USB2 device?

Thanks in advance
Daniel

I'm not versed in pyINDI, but maybe try to use one client object instead of two? Because each client object would receive the two devices and then you just get to choose which one you want to talk to.. if my understand is correct.

Thanks for your answer, but as far as I understood from the SBig info page (www.indilib.org/devices/cameras/sbig-ccd.html, bottom) the indi_sbig_ccd driver supports only one camera per driver:
[cite: "The SBIG driver only support one-camera-per-driver, so if you have more than one SBIG camera, you need to start a dedicated instance to each camera."]
I still tried it, but as I expected, it did not work either.
It shows the same error, so i think, it looks at the same USB port. (In KStars USB1).

Any other suggestions?
Thanks,
Daniel

Yes, that's correct. But this is not what I was suggested. I was suggesting using one pyINDI client to connect to the server running the two SBIG cameras. Maybe this is a bug in pyINDI.. can you use indi_setprop to connect each one individually?

Oh, okay.
That can probably be what I need. My problem now is that:
indi_setprop STXL-6303.DEVICE_PORT_TYPE.USB 2=On
does not work, since there is a whitespace between USB and 2. How do I set a property like this?

Thanks again!
Daniel

How about this?

I tried this, but unfortunately indi does not accept this. I still get:
Malformed assignment: USB
Purpose: set one or more writable INDI properties
1.8.0-tgz
...
(And the same with "\" before space.)

You're correct, indi_setprop fails with this. I just updated it in GIT so please recompile INDI and test with the updated version.

Thanks a lot!

It now works!
