IQ DATA - Regarding

SRINATH

Hi Team,

I am trying to find the angle of arrival using IQ datas in the AOA algorithm in BLE.

I have kept TI cc2642r as transmitter (rtls_responder) and receiver as nordic (nrf52833 dk). I get some iq samples when printing iq. But how can I verify if iq is correct.

I Am getting iq only in a range of (-15 to 15).

    Is the antenna array set up to do switching on itself or have you connected the GPIOs P0.03, P0.04, P0.28 and P0.29 to drive antenna switching? If it's connected to the GPIOs to control switching I think these changes should be sufficient. What output are you seeing from the receiver instead of IQ samples on your end? Could you upload a log file so we can take a look?

    Best regards,

    Simon
