[Bluez-users] Talking to a digital camera

[Bluez-users] Talking to a digital camera

[Pablo Vieira]

Hi,

I'm new to this list so I apologize if this has been treated before.

I want to talk wirelessly to a digicam (a Canon Powershot A75, but most use
similar protocols). These cameras use USB to talk to the host computer and
I'm wondering if I could use any Bluetooth device to serve as a wireless
bridge to the camera, in the same way there are Bluetooth printer adapters
that talk to printers. Actually, I was thinking: would it be possible to use
one of these adapters?

I AM NOT TRYING TO DOWNLOAD OR UPLOAD PICTURES from or to the camera. I just
want the camera's shutter to be released remotely, as well as setting up
parameters such as shutter speed, aperture, etc.

Thanks for any help

Pablo

I haven't heard of any adapter like this, but what you need sounds like
PTP to BIP bridge.

Hi Pablo,

think about the "Reply to All" button ;)

this depends on if the USB descriptors are matching, but in general you
don't have PTP or USB storage on the printer.

BIP means Basic Imaging Profile and the rest you should find out by
yourself.

This thing

seems to support BIP. Sorry for my ignorance, but would it make it usable
for my project?

Thanks

Pablo

I don't think so, because normally the BIP support of printer adapters
are limited to push images from a camera to them.
