Can the firmware of Nordic nRF52833 DK support AoA?

1. Is there a complete demo product?

2. Can the firmware of Nordic nRF52833 DK support AoA? It means that AoA packets can be sent out.

Thank you!

I plan to use TI's AOA antenna array. I already own nRF52832 ev board. 

 I want to know how to send out AoA broadcast packets. CTE packets should be included.

I found the relevant settings in the following path. But I cannot find the DFEMODE setting in the SDK (nRF5SDK16\examples\ble_peripheral\ble_app_beacon\pca10040\s132).

Setting up the transmitter
Configure the Constant Tone Extension (CTE) to set up the Angle of Arrival (AoA) transmitter.
1. Enter DFEMODE.DFEOPMODE=3 to set the AoA mode.
2. Enter DFECTRL.NUMBEROF8US=3 to set the length of the CTE to 24 µs.
3. Enter DFECTRL.DFEINEXTENSION=1 (default) to add the CTE after the CRC.
4. Write the TX data to the RAM.
The frame shall match the required format for an advertising channel Protocol Data Unit (PDU) (CP bit set and CTEInfo=0x18).
5. If the SHORTS.READY_START register is enabled, enter TASKS_TXEN=1 to start the transmitter.
