Hello,
I am using DSLR Dashboard together with my Nikon DSLR without any problems.
Now I need to control my camera via Arduino.
I am looking for the PTP commands to use bulb mode via usb only.
I can switch the camera to bulb and release the shutter, but how do I stop the exposure?
(I found this idea on this website... )

Unfortunately the author says that there is a strong limitation as one could the set the camera to bulb via USB but without the option to capture.
He recommends a regular cable release to release the shutter.
But after testing Bulb in DSLR Dashboard without problem I am wondering if you could help me on my way to USB Bulb for Arduino & Nikon.
Are there any PTP commands to start and end the exposure while being in bulb mode?
Thank you in advance!

Quote: Another rather annoying limitation is capture command, which doesn’t function in bulb mode ( most Canon DSLRs continue to execute capture when switched to bulb, manually or otherwise). Cable release will work as usual so it is still possible to make a HDR intervalometer which can switch between ‘normal’ and bulb modes – all that is necessary is a digital pin on Arduino, a transistor and a couple of resistors.
