I have built your Pro Timer as specified using in essence the same code and hardware that you have documented.
On an Olympus OM-D EM-5 Mk II the Pro Timer controls the camera as we would expect in either Bulb Mode or Manual Mode. On either a Nikon D800, D810 or D750, the Pro Timer works as programmed with the camera in Manual Mode and with the Pro Timer set with an interval time and allowing the Nikon Cameras to trigger at a given allowable shutter speed. However the Pro Timer will not control any of my Nikon camera models in Bulb mode. I have a number of traditional wired intervalometers and all of my intervalometers control the cameras in Bulb mode as configured.
Are there any other reports that the Pro Timer has issues with Bulb mode on Nikon cameras?
Thanks in advance for your input
