UDK1 and Angle-Of-Arrival (AoA)

UDK1 - All-in-One UWB Demo Kit
1

Hi,

one of the UDK1 demos shows the Angle-of-Arrival (AoA) capabilities. This seems to work quite well.

For further evaluation we would like to reproduce this demo and access the AoA data via USB/UART and some software (get AoA data without using “AoAUwbRangingAndAoaDemoApp”).
This software should be able to init the UDK1 hardware (LC13/gray and LC14/white), start ranging sessions and provide distance and angle data between two tags.

For the LEAPS API we have already implemented a small piece of code which allows communication with LC13/LC14 via UART TLV commands (mode “LEAPS UWBS”).
But in this API you can’t find anything regarding AoA.
If I understand correctly the AoA functionality is not part of LEAPS UWBS but provided by Qorvo FiRa UCI (only available when hardware is in mode “Qorvo UCI”).

Now it is not clear to me how to communicate with the UDK1 hardware in this “Qorvo UCI” mode.
Is there supporting software that you can build on?

Thanks

Hi Kirby,

Currently we support the TWR & AoA demo of the Qorvo UCI only using the UWB Ranging & AoA Demo App.

Technically the Qorvo UCI can be controlled using an external application, but you would need access to the FiRa specification and a good knowledge about the Qorvo UCI interface would be necessary. We do not provide support for this at the moment.

Thanks,
TDK
