Nikon 1 V3 was created by Terroll Martin

I have a Nikon 1 V3 that connects to EKOS just fine using the Nikon DSLR driver, but I cannot adjust the exposure. The camera just exposes to whatever is set on the camera itself, For example, if I try to set the exposure to 10 seconds in EKOS, but the. camera body is set at 3 seconds, the exposure will be 3 seconds, even though EKOS says the exposure was 10 seconds. I can change the ISO setting in EKOS and that woks ok. The exposure issue makes no difference whether the camera is in M mode or Bulb mode. The camera and all its settings work great in Entangle.

Any ideas?

Did you check out the documentation here? indilib.org/individuals/devices/cameras/gphoto.html

Going through that documentation didn't help any. I tried using the gphoto2 command line and I did find that the shutter speed configuration (shutterspeed2 in the Nikon 1 V3) showed as configured to read only, so I couldn't set the shutter speed with gphoto2 command line either, This is really puzzling because Entangle has no problems setting any of camera settings and it is built on top of libgphoto.

I have a mirrored Nikon and use the INDI Nikon driver. I would not be able set the camera exposure to 3 seconds and at the same time use bulb mode as in your original example. They are different selections on the same camera control. I have both Manual AND bulb mode selected when using INDI. In the INDI control tab I run without bulb mode being forced (don't know if that makes a difference).

If I enable Force Bulb the camera does nothing and Progress in EKOS does not end until I abort the exposure.

I've tried just about every setting in the camera that I can think of, but nothing allows EKOS to control the Shutter Speed in the camera.

My settings are: in INDI do not enable force bulb. On the camera enable both manual and bulb mode.
If testing in daylight try INDI exposure of 0.001 secs. Does the camera start exposure?

Yes, it does take an image at 0.001 seconds. EKOS shows Capturing at 0.001-second image..., and the image is saved as Test.Light.0.001_secs.001.nef, and the actual image has an exposure of 0.001 seconds.

If I try to set a different exposure in EKOS, say 0.01 seconds, Ekos shows Capturing at 0.01-second image..., and the image is saved as Test.Light.0.01_secs.001.nef, but the actual image has an exposure of 0.001 seconds.

If I try setting the exposure to 1 second, the results are the same as above.

Is it the case that in INDI you have to match one of the camera's predefined exposure wheel selections (even though you use bulb mode)?

Seems that way, yes. I tried setting the camera to Manual / Bulb, then set EKOS to 30 sec. EKOS went through the procedure of Capturing and image for 30 sec, and the camera exposed for 30 sec, and the image was saved as a 30 sec exposure. All good.

Then I tried setting EKOS to capture an image at 10 sec, without changing anything on the camera. EKOS went through the procedure of capturing a 10 sec image, but the camera exposed for 30 sec. and the image was saved as a 30 sec exposure even though the file name said 10 sec exposure. Not good.

I then opened Entangle. At first I could not set the exposure length; it was set at 30 sec and the drop down menu was greyed out. I took the 30 sec exposure and it was saved, Then the drop down menu became operable and I was able to set it to anything; I tried a 10 sec exposure and that works fine. I tried setting the exposure to Bulb, but I couldn't set to any time and it failed. I then set the exposure in Entangle to 5 sec, snd that worked Fien and the image was saved.

I don't have a setup to test, so I'll ask for understanding, perhaps to narrow the problem statement. In the INDI interface if you use the up/down arrows on the exposure value does the value increment/decrement in values that match those built into the camera? If so then the follow up is do those values work.
edit: Looking at the documentation Jasem pointed to the section on exposure is interesting and explains these relationships.
