I have a phone I want to connect to a docking station I am making, via Bluetooth for as cheap as possible. As I understand the situation, all I need is something that can pick up a bluetooth signal from a smart phone, and relay it to a chip (in digital form preferably).
Could this purely be done by a bluetooth antenna? Or does this antenna need to be connected to other components to process the information it is receiving, in which case, it would be better off getting a module like the microchip RN-42?
Apologies if this is a naive question, have tried to do my research but I do not know enough electronic technical lingo to work it out myself.
