Bluetooth HID Command for iPhone Camera Zoom Control

[Nazmus Sakib]

Hi all,

I am working on a project to remotely control iPhone cameras via Bluetooth. I can already emulate the shutter button using the Volume Up command (0xE9). However, I’m looking for a way to also control Zoom In and Zoom Out.

I’ve seen some remote shutter products on the market that can handle Zoom In/Out remotely. Does anyone know how they achieve this?

Thanks.

Hi, 

I recommend reaching out to Apple developer resources or seeking help on Apple forums.
