Hi, I have a project in mind in which I use an android phone to communicate to my arduino and viceversa. I know this can be done with bluetooth, the problem is that it comsumes too much battery power, so I wonder if this can be done with USB cable between ardunino and Phone. (IE.. rooting the phone to be able to access the usb serial library or something like that)
If the previous is not possible, is there a way I can bypass the bluetooth antenna and just get the data straight from the bluetooth module? [LAST RESORT, but I'm willing to do it]
NOTE: I'm kind of new at this, so please be patient with me. I just read Java for Dummies book and now I'm starting with Android developing for dummies, but I have ok skills with C++ and some electronics background, so I think I can pull this off.
