Does STM32WB support Bluetooth AOA (angle of arrival) or AOD (angle of departure)?

Matthew K · ‎2019-05-22

Hi, I noticed this feature from Bluetooth 5.1.

https://www.bluetooth.com/blog/new-aoa-aod-bluetooth-capabilities/

"The new Bluetooth direction finding feature supports two methods for determining the direction of a Bluetooth signal, both of which are based on the use of an antenna array: angle of arrival (AoA) and angle of departure (AoD)."

I have recently purchased the P-NUCLEO-WB55 from Digikey

https://www.digikey.com/product-detail/en/stmicroelectronics/P-NUCLEO-WB55/497-18384-ND/9857029

and downloaded the STM32WB CubeMX codes.

However, although STM32WB supports Bluetooth 5, I couldn't find codes related to AOA or AOD.

Are there AOA/AOD examples available for P-NUCLEO-WB55?

Thanks.

It seems, ST has not much interest in supporting their STM32WB for BLE. I am also looking for answers for similar questions in STM32WB community forum and no success yet. I may wait for some more time and if there no support from ST then I may switch to nRF5340 for Nordic has decent support in their community forums.

Hi ST, can you please answer to Matthew’s original question please?

This feature requires an antenna array to be supported, the Nucleo board does not support it as there is only one antenna. So I don't expect any example code in the WB FW package.
