cc2541有固化在芯片内的唯一码吗?
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 and CC2541, this is a 48-bit IEEE address stored with
least-significant byte first at XDATA address 0x780E.
目前只找到这么一条线索。BDADDR 或由这个转换出的mac地址,手册上说这个区间的为只读信息,但看另一个帖子上说,这个BDADDR 可以改写,疑惑重重啊!
1:不知道cc2541芯片内有没有与芯片绑定在一起的,不可改写的id?
2:如果有要在哪里才能找到这一部分的描述,怎么读,有现成的读写函数吗?
3:如果在这块地址范围内?是否也像BDADDR 一样可以修改?
忘记加另一个帖子的地址了,现在补上 http://www.deyisupport.com/question_answer/wireless_connectivity/bluetooth/f/103/t/62201.aspx
这部分只能读的, 读取方法如下XREG(0x780e)
