Get UID and use it in BLE Local Name

[kcire L.]

Hi,

I am using the STM32WB55 and would like to use part of the chip's unique ID as part of the local name in my BLE application.

I was hoping someone could easily show me how I could do this, or at a minimum, get the UID?

Thanks for any help.

The reference manual lists the location of the 96-bit UID and the UID64, which is probably what you want.

How would I access this?

[TDK]

uint32_t uid64_1 = *((uint32_t *) 0x1FFF7580);
uint32_t uid64_2 = *((uint32_t *) 0x1FFF7584);

You might want something like they're doing here:

I'm unfamiliar with the details of BLE.
