CC2541: Information Page Flash Addresses for DIE ID

About the CC2541 DIE_ID

Hi All,

I'm studying CC2543 BLE broadcaster example code (swrc291), and want to port this example to CC2541.

DIE_ID define in miniBLE.h and the define address as below:

------------------------------------------------

/* Information Page and Flash Addresses */
#define INFO_PAGE_FLASH_SIZE 0x7800 // bits 6..4
#define INFO_PAGE_CC2543_DIE_ID 0x7FF4 // LSB..MSB

------------------------------------------------

It seems DIE_ID is defined in the information page, and i can't find any description in CC254x user guide and datasheet.

my question is " is the DIE_ID address for  CC2541 the same as CC2543 at flash address 0x7FF4?"

    Hi Ke,

    For the CC2541 it probably makes more sense to use the BT MAC address rather than the device ID.

    Cheers,

    In that case you should modify miniBleSetDeviceAddress() and use DEVICE_ADDRESS_PUBLIC instead as suggested by Fredrik. The CC2543 use the device ID to generate a static random device address (DEVICE_ADDRESS_STATIC) because it does not have a programmed MAC address, but the CC2541 does. Refer to section 2.2.3 Physical Memory in the CC2541 users guide:

    "For CC2540/41, this is a 48-bit IEEE address stored with least-significant byte first at XDATA address 0x780E."

    I have make change for the cc2541 IEEE address.
    with my question " is the DIE_ID address for CC2541 the same as CC2543 at flash address 0x7FF4?"
    in deed I want to know the DIE_ID address for CC2541, this I checked in the doc, but did not find it.
