- smaller data means less airtime on the wireless
- less airtime means less power consumption
- less airtime means reduced competition for airtime as more devices are added
- CON: the smaller the data, the less rich it can be. This can be limiting when future devices and features are added
- PRO: the smaller the data, the faster it can be processed by the devices. The computing power provided the chips on the Arduino devices are limited. As these devices will be controlling physical devices in real time, the less time they need to spend processing data, the more time they have to manage their physical devices.
Length - overall size of the packet. Limited to 255 bytes at this time.
Header - contains unique identifier for the packet, whether it is a call or response, addressing information for the target device (or all devices) and type information that indicates what details follow in the next section.
Detail - specific data that supports the call/response indicated in the header.
