First: I'm not a professional. I just want to know what is possible and if i'm on the right track.
Second: I want a little microcontroller which just measures (for example) the temperature and send it to my server (can send/receive bluetooth). It should be a SoC. I googled a lot and found an ARM Cortex M0 at nordic semiconductor which has built-in bluetooth (2,60 $) which I want to use. Before I continue and look for a professional to help me I want to ask you ...
The question: Is it possible to put this ARM cortex M0 with built-in bluetooth on a little board with some pins and connect it to a small power source? Would this work, or would I need a lot of components (resistors to pins, capacitors etc.) on that board?
The solution should be as simple as possible to keep it small.
I also googled for existing solutions, but they where 10 times more expensive than a simple ARM Cortex M0 would cost. I found a little iBeacon/Beacon which would cost 4$ with an ARM Cortex M0 and also some pins to connect some sensors, but it was to large (lot of capacitors, resistors, ...).
