请问 CC2540的蓝牙MAC地址是否会有重复？

关注，256的6阶次方数据还是很大的，通常每一包芯片不会重复的，这个mac是原厂的还是自己另外定义的?

 这个都是芯片的默认地址吗？每一个bd_addr代表一颗芯片？

是的， 就是芯片本身的地址。（至少我们出厂时是没做更改， 询问客户也说没改过）

The Information Page is a 2-KB read-only region that stores various device information. Among other
things, it contains for IEEE 802.15.4 or Bluetooth low energy compliant devices a unique IEEE address
from the TI range of addresses. For CC253x, this is a 64-bit IEEE address stored with least-significant
byte first at XDATA address 0x780C. For CC2540/41, this is a 48-bit IEEE address stored with
least-significant byte first at XDATA address 0x780E

你的是这个地址吗，用SmartRF Flash Programmer读一下试试。
