I have recently bought a Bluetooth HC-05 Module, and have followed many tutorials on integrating it with an Arduino, or a microcontroller. However I got interested in whether it is possible without one. And the task I need to achieve is pretty simple, just switching an LED on/off. The official bluetooth documentation is impossible to read, so I'm asking the question here, since I know many of you are experts in the subject.

I found some example code on a website, this fellow is doing almost exactly what I'm doing, just the information is going from phone to Arduino, not Arduino to phone.
All the code is downloadable, and I've checked it out - I'm going to try the PDE, and see if I can connect from my Mac and U8300.
It also includes constructs for the code I need on the phone side, which was going to be my next question after this one - two for the price of one!

Have a look, its said in the description that (paraphrase) "the initialisation sequence must be done right..." so I can now use this code as a guide.
Hope this helps!

Cascaded 4017 decade counters, pulsed by a single 555 timer. Each pulse makes the 4017 light the next one in sequence, which is then passed onto the next 4017, etc.

Think of all the interfacing that needs to be done. The module can't put a pin high when you send something to it, or low when you send something else. It's much more advanced, and involves communication standards that use timing. So if you would do this with 'simple components' (logic ports and the like) it would get extremely advanced, and you would simply have a little microcontroller.
