MAC ADDRESS AUTOMATICALLY CHANGE

[trananh]

Hi all,

In my application, I take mac address of chip and make major, minor value (device 's ID) and I need mac address is a constant value. As I know, mac address is a unique value for each chip but on my test it always change. Can you tell me what problem here ?

For example: The first time I turn on device, mac address is ca676b42db50. The 2nd time I turn on device, mac address is eb84ffada44a. .......... Something like that, it always change

Thanks and regard Anh Pham

No, I don't change anything. Moreover, I have many device but this situation happen in only 1 device so how do you think? Is it hardware problem?

And what do you mean about "the SoftDevice is unable to get an address from FICR"? Something wrong in SoftDevice?
