CC2541获取连接设备蓝牙MAC地址

CC2541获取连接设备蓝牙MAC地址，得到的MAC地址是虚拟MAC地址还连接设备实际的蓝牙MAC地址？

CC2541 BLE能得到连接设备实际蓝牙MAC地址嘛？

YiKai Chen：

這要看你连接的蓝牙设备，如果连接的蓝牙设备回應是虚拟MAC地址，當然就是虚拟的，但是據我所知大部分都是回應实际的蓝牙MAC地址

我们产品中CC2541是与苹果手机和安卓手机连接，我测试发现得到的都是虚拟MAC地址。为什么手机不回应实际的MAC地址

Viki Shi：

连接的设备是手机吗？连上以后获取的应该是手机蓝牙的实际mac地址，但是有些手机会使用随机地址，看具体品牌或型号

手机会使用随机地址，根据这个地址可以解析出实际地址

可能是系统安全考虑吧，绝大多数的手机的蓝牙地址的都是虚拟的，如果你是芯片或者CC2541或者CC26xx，可以设置为

地址模式为ADDRMODE_PUBLIC
{ADDRMODE_PUBLIC= 0x00,//!< Always Use Public AddressADDRMODE_RANDOM= 0x01,//!< Always Use Random Static Address/// Always Use Resolvable Private Address with Public Identity AddressADDRMODE_RP_WITH_PUBLIC_ID = 0x02,/// Always Use Resolvable Private Address with Random Identity AddressADDRMODE_RP_WITH_RANDOM_ID = 0x03,

这个设置后可以得到手机实际MAC地址？

这个API可以得到实际MAC嘛

這個還是會跟手機回應你的有關係，你得要自己測試才行

In addition to the described services, BLE supports a mechanism called privacy feature, which allows a device to use private addresses and frequently change them. The privacy feature mitigates the threat by which an adversary can track a BLE device. The private addresses are generated by encrypting the public address of the device, which can be resolved by a trusted device that has been provided with the corresponding encryption key.
