case about nRF52833 AOA AOD

peter.min

Hi,

IC：nRF52833

Test sample path：

ncs\v1.7.0\nrf\samples\bluetooth\direction_finding_connectionless_rx

ncs\v1.7.0\nrf\samples\bluetooth\direction_finding_connectionless_tx

The test results：

1.How to use this data?

2.Is there any relevant information to provide: about algorithms

3.How do you map each IQ data to each antenna or distinguish which antenna produced each data?

Thank you for all your assistance.
Kind regards,
Peter.Min

    Hi Peter

    There's no point in looking at raw IQ data when it's received, and you need to convert this data to a vector in order to review it and use it for direction finding. Please check out this page for example, for information on the formulas used to make an AoA algorithm that translate between polar and rectangular form.

    Best regards,

    Simon
