Angle of Arrival/Departure (AoX) Utility#

RAIL Angle of Arrival/Departure (AoX) Utility#

This optional software component can be enabled to include default functionality related to AoX configuration. AoX allows the Bluetooth stack to estimate the relative angle of another radio based on samples from multiple antennas.

The RAIL AoX Utility is only necessary if 2 or more antennas are configured. If fewer than 2 antennas are configured, CTE(constant tone extension) data can be transmitted or received on the default antenna.

Configuration Options#

The following configuration options can be changed:

• Number of AoX antenna pins(0-6)

The following hardware options can be changed:

• GPIO pin for each antenna
