蓝牙Bluetooth技术手册规范下载
http://www.crifan.com/summary_bluetooth_specification_download/
【背景】
之前就已经整理和转帖了和蓝牙技术相关的一些内容：
【资源下载】bluetooth 协议 spec specification
蓝牙1.1、蓝牙1.2、蓝牙2.0（蓝牙2.0+EDR）区别
但是发现上述spec下载地址失效了。
所以继续重新找蓝牙的spec。
【整理过程】
1.google搜：
bluetooth spec download
就可以找到：
Specification | Adopted Documents | Bluetooth Technology Special Interest Group
中包含了所有需要的蓝牙的协议规范。
包括了核心（Core）的spec，一些profile（Profiles, Services, Protocols and Transports）等等。
下面，整理如下：
