We have a custom radio protocol that manipulates the radio registers directly (on the '32) and I'm evaluating whether or not we can switch to the '33 to use it's angle of arrival features.
The thing that trips me up, is that it seems we have to operate the radio in BLE 1 Mpbs mode to use the AoA feature. Is it possible to operate in this mode and just not use Bluetooth protocol stack via softdevice? Silly question I know, but there must be an important reason why there is a separate Nordic and BLE mode for 1 Mpbs. Perhaps it's because the radio would be able to receive BLE packets from other devices and that would be bad.
The point is, is that I'd like to use the angle of arrival feature in our proprietary radio protocol currently implemented on an NRF52832 by switching to the '33.
