Bluetooth 개요

Android Bluetooth를 개발하기전에 Bluetooth 통신에대한 약간의 이해가 필요합니다.
Bluetooth Process를 간단히 설명하자면 주변에 연결하려는 디바이스를 찾고
찾은 기기중 연결할 기기에 인증을 받은 후 그리고 나서 통신을 합니다.

이 내용은 크게 Discovery,Pairing,Connection,Streaming 4가지 STEP으로 나눌수 있습니다.

1.Discovery

주변 디바이스 검색 합니다

• Discovery는 주변에 블루투스와 연결 가능한 디바이스를 검색하는것 입니다.
