Hey Karl,
I tested the driver but unfortunately it kept crashing, it looks like its missing a file
"Driver indi_pentax: indi_pentax: error while loading shared libraries: libRicohCameraSDKCpp.so: cannot open shared object file: No such file or directory"

I have attached the complete log.
Thanks,
Lenny.

There is a missing dependency. All you should have to do to get it going is install the libricohcamerasdk library:
sudo apt install libricohcamerasdk

I've updated the package, but I'm not sure how long it will take for the fix to get into the nightlies.

Thanks Karl,
I was able to get the camera to connect successfully once i installed the SDK, however i was not able to take any pictures successfully. I tried 1 second and 31 second images in bulb mode each time the shutter opened and closed immediately, and finished exposure prior to the end of the 31 second limit. When i tried in manual mode the shutter would fire but then would not close and failed to download. I tried a 3rd attempt in Bulb mode at 60 seconds and noticed that the countdown timer did not go above 30. Its like it does not recognize that the camera is in bulb mode.

I have attached the log file from the test. For the heck of it i tried to connect in PTP mode but it didnt find any device.

Thanks,
Lenny.

Thanks for testing it out, Lenny. It looks to me like it never recognized you were in bulb mode. And then the camera looks like it got into a weird state. I think we had a similar problem on K3II. I wish I had something besides the K-70 to test with.

I'm not sure how much additional testing you're up for, but if you have some time, it'd help to know:

1) Can you check to see if it downloaded any images to your device? The log seemed to indicate it did, but of course that doesn't necessarily mean anything.
2) If you start the driver in M mode, and never switch to another mode, what are the results?
3) If you haven't already, could you by chance download pktriggermode by itself and let me know how that works with your camera? The driver is just wrapping the code for pktriggermode, so if you've used pktriggermode before and it worked, then we're having a driver problem. Otherwise, there's a fundamental problem with pktriggermode, and there may not be much I can do.

If you can respond to those questions, I can spend some time this weekend updating the driver a bit so it can spit out more helpful debug information.

Thanks,
Karl

I should mention that when the camera gets into a weird state, sometimes you have to pull all power (i.e. take out the battery) before it will behave normal again--turning it off is not enough. So for #2, what I'm looking to find out is what happens if you start totally clean with both the driver and the camera in M mode.

Hi Karl ,
I will test that out later on, I should note I had tried Pktriggercord back in the day but always had trouble with Bulb mode, but let me complete the tests again and see what happens.

I should have also said yes it did download images on some of the tests

Thanks,
Lenny.

Karl,
see updates below :
1) Can you check to see if it downloaded any images to your device? The log seemed to indicate it did, but of course that doesn't necessarily mean anything. - On some of the tests yes it downloaded an image

2) If you start the driver in M mode, and never switch to another mode, what are the results? Inital test at 1.5 seconds shutter opened and closed for 1.5 seconds but it got stuck in waiting to download image. I aborted that attempt and tried 2 seconds, shutter fired what sounded like twice and then opened for 2 seconds and closed, but the downloaded image seems to be from the first shutter snap as the image was perfectly exposed and not over exposed at 2sec and 800iso. Repeated 2 second shot, again shutter sounds like it fired twice. Tried 31 second exposure and counter started at 31 but finished downloading after 2 seconds even do shutter was still open must have read from buffer. tried it at 30 seconds max exposure for manual mode, again it completed after approx 2 seconds and read from buffer, once 30 seconds elapsed shutter closed.

3) If you haven't already, could you by chance download pktriggermode by itself and let me know how that works with your camera? The driver is just wrapping the code for pktriggermode, so if you've used pktriggermode before and it worked, then we're having a driver problem. Otherwise, there's a fundamental problem with pktriggermode, and there may not be much I can do. I cant seem to download pktriggercord for ubuntu says package is not available, i had tried it in windows a year or 2 ago with no success, but if needed i could try it again in windows

log file attached from test

Okay, seems like it's not getting that initial image from the buffer correctly (it thinks its a 0 size image), and from that point on the buffer is lagging behind one exposure. That gives me a few ideas to test at least.

It might be helpful to at least see what you can do with pktriggercord on Windows. That will give us a baseline of what we should be shooting for with the K30 here.

So i tried pktriggercord on windows, it dosent recognise the camera model in the json file. So its not able to change mode or set bulb settings. So when camera is in Manual mode It works fine i can take pictures of various lengths up to 30 seconds with out issue. If i knew how to get it to recognize camera model then maybe i could test changing the settings. If i start it up in Bulb mode it gives an error as sen in attached image

Thanks. That's strange that it's not recognized in bulb mode, as the K-30 is listed as supported (as opposed to partially supported) on the pktriggercord website. I'll work on trying to get M mode to work for now, and then see what I can find out from pktriggercord about the bulb mode problem.

So i managed to get the camera to be recognized by editing the JSON file, So the version of PKtriggercord is 0.85, I downloaded the git from github.com/asalamon74/pktriggercord and had a look at plsr.c and got the hex address for the K30, once I updated this the camera was recognized and the settings showed values for the bulb configuration where as before it was unknowns.
See attached
If i started up the camera on U1 or U2 I was able to configure these to any mode I wanted, except Bulb. Every time I switched to Bulb mode or tried to start up in Bulb mode I got the error posted in my last post on referring to line 2240, which in looking at pktriggercord.c on github is actually referring to line
2304 and this function
G_MODULE_EXPORT void user_mode_combo_changed_cb(GtkAction *action, gpointer user_data) {
    DPRINT("user_mode_combo_changed_cb\n");
    pslr_gui_exposure_mode_t val = gtk_combo_box_get_active(GTK_COMBO_BOX(GW("user_mode_combo")));
    if (!status_new) {
        return;
    }
    assert(val >= 0);
    assert(val < PSLR_GUI_EXPOSURE_MODE_MAX);
    if (status_new == NULL || val != status_new->exposure_mode ) {
        pslr_set_exposure_mode(camhandle, val);
    }
}


So i think the problem is in plsr.c where it dosent determine the camera has actually been put into bulb mode.
pslr_gui_exposure_mode_t exposure_mode_conversion( pslr_exposure_mode_t exp ) {
    switch ( exp ) {
 
        case PSLR_EXPOSURE_MODE_GREEN:
            return PSLR_GUI_EXPOSURE_MODE_GREEN;
        case PSLR_EXPOSURE_MODE_P:
            return PSLR_GUI_EXPOSURE_MODE_P;
        case PSLR_EXPOSURE_MODE_SV:
            return PSLR_GUI_EXPOSURE_MODE_SV;
        case PSLR_EXPOSURE_MODE_TV:
            return PSLR_GUI_EXPOSURE_MODE_TV;
        case PSLR_EXPOSURE_MODE_AV:
        case PSLR_EXPOSURE_MODE_AV_OFFAUTO:
            return PSLR_GUI_EXPOSURE_MODE_AV;
        case PSLR_EXPOSURE_MODE_TAV:
            return PSLR_GUI_EXPOSURE_MODE_TAV;
        case PSLR_EXPOSURE_MODE_M:
        case PSLR_EXPOSURE_MODE_M_OFFAUTO:
            return PSLR_GUI_EXPOSURE_MODE_M;
        case PSLR_EXPOSURE_MODE_B:
        case PSLR_EXPOSURE_MODE_B_OFFAUTO:
            return PSLR_GUI_EXPOSURE_MODE_B;
        case PSLR_EXPOSURE_MODE_X:
            return PSLR_GUI_EXPOSURE_MODE_X;
        case PSLR_EXPOSURE_MODE_MAX:
            return PSLR_GUI_EXPOSURE_MODE_MAX;
    }
    return 0;
}

made some progress was able to get pktriggermode to allow bulb mode by setting plsr_model.c line 981 to
{ 0x12f52, "K-30", false, true, **true,** false, false, false,

How ever when I take a picture the shutter fires and closes and then the countdown starts so its like it dosent know to hold the shutter open......
