昨天，Bluetooth v3.0 + HS (蓝牙 v3)发布

Bluetooth v3.0 如期而至，带来的会是什么。现在还不知道。不过可以期待，最引人瞩目的当然是802.11 PAL带给人们的高速享受。

NEW FEATURES

Several new features are introduced in Bluetooth Core Specification v3.0 + HS.
The major areas of improvement are:
• AMP Manager Protocol (A2MP)
• Enhancements to L2CAP including
• Enhanced Retransmission Mode and Streaming Mode
• Improvements to the L2CAP state machine for AMP channels
• Fixed channel support
• Enhancements to HCI for AMP
• Enhancements to Security for AMP
• 802.11 Protocol Adaptation Layer
• Enhanced Power Control
• Unicast Connectionless Data
• HCI Read Encryption Key Size command
• Generic Test Methodology for AMP
• Enhanced USB and SDIO HCI Transports

据我估计，一年之内普通百姓还不会体会到新标准带来的性能提升，不过至少可以从老产品价格上获益。加之经济的萧条。或许要两年甚至更久时间，我们才能看到新产品的普及。当然这也决定于Bluetooth SIG和厂家的推广策略。

总之，从我做毕设以来关注Bluetooth（蓝牙）到现在，发生了不少事情。毕设也快结束了，希望能找到我自己的归宿。也希望蓝牙能走的更远，给人们带来更便宜更高效的产品。
