Wrong IQ data receive (direction finding)

Hi,

I have made an emitter (with nRF52833) and a receiver (with nRF52833 too) and i already succeed to receive data and print IQ data from an antenna array but the IQ data are wrong.

Here is the problem: I place my transmitter on the side of the antenna 1 and thanks to the IQ data i received from each antenna i trace a graphic of the phase of each antenna to verify antenna 2, 3, 4 are late (phase difference) compare to signal 1 but it's not the case:

I made several test but they are all wrong..

Please i really need help so if you have an idea i'm more than interested :)

Hi,

Could you tell me based on which example have you implemented your project.? Is the transmitter and receiver based on the samples provided by Nordic.?

Kind Regards,

Swathy

Hi, thanks for the reply :)

I use "direction_finding_directionless_tx" for the transmitter and "direction_finding_directionless_rx" for the receiver
