EDU_BT01 - Chapter 1: The Many Communication Modes of Bluetooth LE
Bluetooth LE is well known as the wireless communication technology that lets your phone connect to your activity tracker and synchronize data repeatedly throughout the day, all without any noticeable impact on the battery level of either device. Efficient communication that involves frugal use of energy was one of the primary goals that were pursued in designing Bluetooth LE, and it’s fair to say that it delivers well on that goal.
As end users of such products, we’re accustomed to the connect, exchange data, disconnect sequence that Bluetooth LE uses, and we talk casually about our devices connecting (or occasionally, not connecting when we’re having problems!).
But did you know that a connection is a specific technical state and that connection-oriented communication is just one of several communication modes that Bluetooth LE can use?
In this chapter, we’ll introduce each of the communication modes and look more closely at each of them in subsequent chapters. |
