I'm trying to make a new app that talks to a bluetooth low energy chip. I have never played around with bluetooth or BLE before, so I'm trying to learn as much as I can about it. I know that I have to implement Apple's Core Bluetooth framework, and from there I have a few very basic questions.
Is the code for writing apps with classic bluetooth the same as apps with BLE, or are they different?
What's the deal with AT commands, I tried reading a bit into it but are those something I have to mix with Objective-C while making a call to the device?
Central and peripheral. I noticed that when you are making two devices talk to each other, one has to be central and one peripheral. Lets say I make an app that turns on a light via a bluetooth low energy chip. Would the iPhone be the peripheral, and the chip / light be the central?
