I've compiled the code for indi gphoto driver.
When Indi start, it detects the mode fallback speeds.



However, when trying to pass the shutterspeed to the cam, it fails and returning Failed to set widget...

Thanks. Please git pull and try again.

hello,

This doesn't solve the issue. I have enclosed logfile.

Bruno

For some odd reason, your log file does not include all the debugging data... even though logging is turned on. So it's missing quite a few points that should have shed light on this...

You could also file a bug against libgphoto2 since the library is supposed to return this list like other cameras, so something is missing here and it is better fixed at the source instead of temporary hacks like the one I added.

hello,

Sure. I will try to open a case in the libgphoto2 project, if the issue is not in indi driver, its not worth tweaking the code for bad reasons.
Will come back to you when progress will be done on the libgphoto2 side.

Damn... there's something strange:

I had installed Ubuntu 16.04 Lts on an old Asus EEEPC with Indi etc... And the Sony A7S worked!!!

Now the EEEPC is really too slow and I decided to recover an ASUS T100; After several problems I finally managed to install Kubuntu 18.04.1 on Asus T100; I put Indi etc...with last gphoto... And Sony doesn't work anymore!!! Now i find all the problems marked by other users...


In attachments you can find the libgphoto version used on asus eeepc (i try this evening and sony works correctly)

Now, Is there a way to install this version of Libgphoto on Kubuntu 18.04.1? (I honestly do not want to redo the operating system on T100 with the risk that it does not work)

or maybe it's easier to create a special driver for the sony using the 2.5.16-2 version of libgphoto?

Thanks

I forgot one thing:

This is the version of Gphoto installed on EeePC.
(2.5.15-2)

I do not know how the communication works between Gphoto, Libgphoto and Ekos but I think it might be useful to know that with these versions of the software the Sony A7S is usable.

I hope this information can be useful to find a solution

I would try to uninstall all Gphoto and Libgphoto and reinstall old versions on the ASUS T100 but I'm a noob and I have no idea how to do without combining disasters

You can always build libgphoto2 from source, but it takes a little bit of experience to get that going. If you can do this, then you can even do something called 'git bisect' which is a way to find which code was responsible for introducing the problem. But you could start with compiling libgphoto2 first from source.

Ok, i will try

only few things:
1: i must unistall gphoto and libgphoto before install hold versions?
2: if i can install hold versions, what's going on when i will launch "apt-get upgrade" and "apt-get upgrade"? Gphoto and Libgphoto will be upgrade to the last release?

For build hold versions:

1: download the hold packages from gphoto website
2: unzip packages
3: cd libgphoto2-2.5.16
4: ./configure
5: make
6: sudo make install

7: redo same steps for gphoto2-2.5.15

Correct?

Thanks

Not work…

After a few attempts i downgraded gphoto and libgphoto (Or at least I think so, see attachment for details) but sony doesn't work...

I don't know the differences between "candidato" and "installato"...

maybe there something between Gphoto and Indi/ekos that must be done? Or can be something about (k)ubuntu 16.04 and 18.04?

Hi Jasem, i see your replay in gphoto gitub. Thanks so much for your excellent support
.

Yesterday i made a lot of tests with sony a7s. Here some info if can help you:

1) My old configuration where sony works and new configurations where doesn't work return me the same info about list shutterspeed with gphoto2 command:


/main/capturesettings/shutterspeed
Label: Velocità otturatore
Readonly: 0
Type: RADIO
Current: Bulb
END

the only (apparently) difference is the kstar version (2.9.7 new and 2.9.5 old) and gphoto2-libgphoto as report in forum topic. But downgrade gphoto/libgphoto as my old configuration doesn't fix the problem. So the only difference appear the kstar version….maybe some changes about bulb/shutterspeed?

2) anyway i can change shutterspeed with gphoto2 command.( gphoto2 --set-config shutterspeed=xx).

For example i can set in camera 1 second using 10/10 or 1 values.. for 30" can use 30 or 30000/1000.. ecc. to set bulb mode i can use a lot of value: 31000/1000, 40000/1000, 32, 35 ecc,...

3) Important: in my old configuration where sony works i can set the exposure in ekos pannel but in camera the setting seems to be ALWAYS bulb also for esposure < 30 sec. Seems to change only the time of bulb exposition not the shutterspeed…..

4) in my old configuration i can take photos from sony using "Gphotoccd" or "sonydslr" in ekos setup. sometimes i have Crash warning but works anyway. in new configurations sony doesn't work (sonydslr or gphotoccd)


5) i test gphoto command for bulb mode and this works:


gphoto2 --set-config bulb=1 --wait-event=40s --set-config bulb=0 --wait-event-and-download=2s
