4.1. 

step1. θ1 θ2 θ3 θ4 = ATAN(Q/I)...

step2. Δθ= |(θ1-θ2)| ... |(θ2-θ3)| ... |(θ3-θ4)| ... |(θ4-θ1)|

step3. last = arccos (∆θλ / 2πd)

Locator_A

Locator_B

This doesn't look like the actual angle

Where have i went wrong?

Hi

First off, I'm not familiar with these antenna boards you are using, so I can't guarantee that they're working correctly. Anyways, the raw IQ data is not usable by itself, and needs to be converted into vector form to be reviewed properly. This is not an algorithm Nordic will provide I'm afraid, but you can check out this page for information on the various formulas used to translate IQ data between polar and rectangular form.

Best regards,

Simon

Hello
In fact I also refer to this page
But what I don't understand is what formula needs to be used to achieve the purpose

[Simonr]

I'm sorry, but we don't have any input on how you set up/create your AoA algorithm, and I would suggest looking up different pages on the internet to see how it's done.

Best regards,

Simon
