Precision aoa

Hello I have a project where I have to measure a distance between two objects.

The measurement method has already been found, however for it to be viable I would need a precise angle measurement via Bluetooth (± 0.5 °).
So I looked at the AOA which seems to me the most suitable for my use.
I would like to know if it is technically possible to obtain such precision of angle measurement via the aoa by Bluetooth with (nRF52805).

Thank you in advance!
