Is there any way to send a bluetooth signal from arduino to a smartphone camera?
We're building a 3D scanner using a smartphone. The arduino controls a rotating disc that's driven by a servo. Every 24 ° the servo stops and a signal should be send from the arduino bluetooth module JY-MCU to the smartphone so it takes a picture.
The programming of the servo is easy but I can't seem to find how to get the bluetooth module to operate the smartphone's camera.
I was hoping to find someone here that has already done this so it saves me the programming
One more thing, and this is an arduino question, are there any libraries need for sending bluetooth signals and what kind of signals can a bluetooth send and how do you determine what the bluetooth module sends?
If i send something with the bluetooth module, should I use HEX code? I found that all I need to do is to send CR (enter) so the smartphone will take a picture. In order to do so, the module should send a CR code to the smartphone. But I'm not sure what code to use, binairy, hex or...?
Ok, managed to solve this problem . Anyone who's interested how, PM me
