Topic: Bluetooth 4.0 project (Read 35 times) previous topic - next topic



I have been working on a project to make my cars accessories turn on when a rfid tag comes into range. Since the rfid tags only have a range of 2 to 3 inches, I didn't think that would be a great idea. So i started to think of some other wireless technology, and I figured Bluetooth. I was wondering if there was some way that when my phone connected to the arduino via Bluetooth, that the arduino can make sure its my phone by checking the hardware id and then if its a match, activate a pin to turn on a relay. I just am not sure how to implicate this in code. Can you program the arduino todo something by just a device connecting to it?


Not directly, you could prg a app that would send a string to the arduino therefore verifying the device and have it prg so that it did it at start up.
