How to apply AoA on nRF5340

[Emma Chen]

Hi all,

I am a beginner of nRF5340, trying to test AoA function for indoor positioning.

I'm wondering if there is any helpful document that goes through the whole process of this issue step by step.

I have tried to run the sample code, but I got the error as shown in the figure, and I really can't understand the meaning of the whole code.

Also, I only have one nRF5340, and I download nRF Connect for mobile, is it possible for me to finish indoor positioning with this two equipment?

If it is possible, how to do that?

Thanks!

Hello!

In the sample description you link to, it is mentioned that an antenna matrix is required to operate in AoA mode. Do you have this?

Also, have you followed the steps in Antenna matrix configuration for angle of arrival mode?

Best regards,

Einar

Hi,

Thank you for reply.

Since I am really new for this topic, I don't know how to do this...

Should I prepare an antenna? or I can use the mobile phone instead?

To configure the antenna matrix, is there any useful document that could help me learn more?

Best regards,

Emma

Hi again!

As described in the sample documentation, an antenna matrix is required to operate in AoA mode.

To get started you can find more information from Nordic here, and more information about direction finding in BLE here.

For more information about antenna hardware, please contact the regional sales manager of your area. If you don't have their contact info, please fill our our sales related questions form here to get in touch.
