Re: STM32WB55 BLE address
toggle quoted messageShow quoted text
I got the error below:
undefined reference to `bt_ctlr_set_public_addr'
Yes I included <bluetooth/controller.h>
I don't know if any config is missing and how public BLE address is assigned for this board.
Anyway I can connect to nrf connect and ST BLE sensor android app.
The battery service is working.
Now I am finishing a custom service.
Thanks, I'll check it out.

I have not yet worked with any of the bluetooth APIs, but this thread
peaked my interest because I am also evaluating the STM32WB55 for an
I did a quick search through the bluetooth API and found the function
bt_ctlr_set_public_addr . I started digging into its implementation,
but I was not able to figure out how this function relates to the rest
of the bluetooth system, or how it relates to the STM32WB55 LL/HAL.
I would recommend trying this function to see if it meets your needs.
Please let me know if it works! I'm definitely curious to know how this
might work with the STM32WB55.
