I'm going to work on a project in which I need to take your experience into consideration to which path should I go to.
I need to design a wireless circuit at max size 5x2 cm, that has a thermostat and a MCU. I need to cover an area of 1km, so I would go for the ZigBee approach. There is also a design problem with battery life, so I need also to have the least power consumption that can be done.
Do you think with that design specs, is it possible or no?
So in general I would care about:
I have found this chip, the CC2543/44. How do you like it and is it suitable for my design?
