Can I use Bluetooth Low energy devices as micro controllers directly instead of communicating to Arduino e.g. HM-10/11 or even HC-05/06 ? If so what are limitations e.g. can I hook sensors or control other stuff like LEDs or transistors with PWM ?
I have built a motion sensor, which consists of Arduino, Bluetooth Low energy HM-11, battery and sensor itself. It worked just fine, but one guy told me that Arduino may be completely unnecessary and that Bluetooth module could replace its functionality ! I then started digging for information, and either it's impossible or I am terrible at googling. Everything I found was info about some kind of development kits for HM-10/11, also pin outs of those boards. They do have some IO pins, which can mean it's possible, but I found no tutorials nor examples on how to program those boards and use with other components.
