请问蓝牙可实现一对多语音通信吗？

蓝牙是一整套的点对点协议，并不包含广播。从物理层做，满足其跳频，调制等要求，
尽管可以自己动手开发实现广播功能，但已经不能称之为蓝牙了。而用集成芯片的话，HCI层以上的基本无法实现。
我曾经也问过这个问题，把别人给的回答贴出来，可以参考一下
Depends what you mean by broadcast:
1.At the physical level it is a non-directional radio signal and hence is br
oadcast - a blueband device can poll all the surrounding devices.
2.At the next level up in the stack it is a point to point protocol and not
a one-to-many protocol.  It is not possible as far as (I am aware) to broadc
ast a stream (e.g audio data) to multiple receivers over a single Bluetooth
adapter.
3.At the application level it is possible to broadcast objects by polling al
l the surrounding devices and sending files to those devices that support th
e Object Push Profile or any other Profiles built on the OBEX protocols.
