How do I start on BLE Direction Finding?

[Florian Saurwein]

Hello, my company wants to get started with BLE direction finding. Maybe you can help me on how to setup some hardware. NRF52833 DK seems suitable but then I have no clue on how to implement the antenna array. Furthermore, my background on C Programming and knowledge about NRF chips is rather shaky to non-existant. Perhaps, you can give me advice on what would be the next steps for me start developing and eventually implement the Direction finding technology. Wish you all the best, Florian

Hi

I'm sorry, but we don't have any reference design for direction-finding antenna arrays as of yet. We are currently working on a solution with a development kit + antenna array + firmware. As of now, what we can say is that an array and external RF switches will be necessary to switch between the antennas in your AoA/AoD design. You can read up on Bluetooth 5.1 in this blog post.

We do not have anything official for you as of yet I'm afraid, but keep an eye out for news from us regarding this.

Best regards,

Simon

Hi Simon, do you have any ETA on a dev kit which would enable us to work with direction finding?

Thanks :)
