How to get angle of arrival ? (BLUETOOTH 5.1)

Projects General Guidance

Hi!
I'm trying to do a "follow me" project, and I see that you can get the angle of arrival of a bluetooth signal with the new bluetooth version.

Can we use a bluetooth 5.1 module to retrieve and use the angle of arrival value in an arduino project?

Thank you!

IMHO Angle of arrivall is not yet handled with Arduino, hardware+software(library) lack for this interessant 5.1 functionality.

Does not the Angle of Arrival require specialist hardware, as in a receiver with multiple antennas etc ?

Do you have one of these base stations ?

Yes, but maybe we could use another module to calcul it, and after, send the value in the arduino?

If not, can you tell me what I could use as hardware to be able to use the AoA?

Yes, it's true.
I don't have any hardware, I'm trying to figure out which one to use.

You also need to consider the angle the of the signal being sent by the other device.

Let us know if you manage to find Arduino-compatible versions of the special receiver or transmitter modules, and a library.

Edit: six months ago, U-Blox engineers managed to cobble together a working gizmo:

After further research, I came across this video. it looks amazing. it doesn't use Arduino but maybe by being interested in it, we could carry out our follow me project.

Hey!
I come back to you.
I saw that the video kit was 200 euros...

But I found another company that provided modules of all kinds that supported AOA and AOD, these were Nordic SemiConductor modules.

But I'm not sure how they work. Another user provided me with a lead to continue my research.

  1. 2017 or so cheap "bluetooth beacons" started arriving, $5 -10. arduino-based beacons as well. credible indoor self-positioning can use beacons.

  2. ESP32 UWB Indoor Positioning Test - Makerfabs
    arduino based ultra-wide band positioning systems show $30 in 2021.

TI has cheap ($12 for 10 units) bluetooth positioning tags
