CC2540 Device's Address on SimpleBLEPeripheral_Init() phase

Vasiliy Bogatov

Other Parts Discussed in Thread: CC2541, CC2540

Hi All,

I need to read device adress before GAP/GATT initialization (to form device name from it). I know that GAPRole_GetParameter(GAPROLE_BD_ADDR, ownAddress); gives access to this information, unfortunatelly for this GAP should be launched. I have to read this information on early init phase. I use "SimpleBLEPeripheral" project as reference. So, how to obtain device address in SimpleBLEPeripheral_Init().

More specific:

1. whan NV is for device address storage

2. how to obtain address in SimpleBLEPeripheral_Init()

Thanks a lot!

P.S. Why this theme is ignored like these too:

Reading CC2540 IEEE primary address programmatically to create a unique chip address

Reading CC2540 IEEE address programmatically before GAP Init

If it is super secret, then just answer - no, why TI drop their customers???????????????????????????????????????????

You can try getting the device address from XDATA address 0x780E for the CC2540 or CC2541.

You can look at the user guide at the following link.

Thanks!

For future generation more specific:

__xdata __no_init uint8 ID[6] @ 0x780E

For basic NV storage, it is easiest to use osal_snv_write() and osal_snv_read(). If you need something more elaborate, the code and osal_snv.c provides a good starting point to understanding how to access flash with hal api's.

Hi Richard,

I understand clear how to work with OSAL_SNV and use it in my work. But what is OSAL_NV_ID for MAC in case of topic? It seems to me the only way to read primary id is method shown above.

Thanks,

You're right, MAC/IEEE address is not accessible via osal_snv. (mixed up a couple threads, sorry)
