Arduino BT signal to smartphone camera

Projects General Guidance
1

noob here.

Ive searched everywhere, and ive seen many tutorials where you control an arduino from your smartphone, but is there a way i can send a BT signal from my arduino to my smartphone so that it automatically takes a picture?

id also want to trigger the instance with an IR remote.

every time i search i always come up with a shutter trigger for a dslr, never for the actual smartphone camera.

TIA

No. There needs to be some application running on the phone, listening to the bluetooth port. That application could be written so that some piece of data told it to take a picture.

How to do THAT depends on the phone that you have.

thanks for your response.

So i need an app open that helps communicate with the arduino huh?

i doubt the phone will be able to take a photo from outside of the camera app, which needs to be running.

i have an samsung s6. i will be looking into this further.

thanks for saving me endless searches.
i will have to look into other options.

i do have a BT shutter that i guess i can press, but i find those unreliable.
