Dear team,


The current IQ sample information is as follows:

Can I modify the script so that the extracted IQ samples can show which antenna in  antenna array?

I want to know which antenna (antenna 1,2,3) in antenna array1 is used.

The code in this script is as follows

How to modify it?

    Hi Susan,

    I am sorry but it is not currently possible to know which antenna was used to measure a given sample.

    With that said, if the reason why you want to do this is to verify if the toggling is correct, you can rather use a logic analyzer to verify the status of the IOID 27, 28, 29 and 30 (you will find the correspondence between the pin state and the antennas in this document ).

    To finish, if you really need to print out this information, then a modification of the embedded code is required (i.e. the code flashed on the CC26xx), especially in the file AOA.c

    I hope this will help,

    Thanks for your support!

    So how could i modify the code flashed on the CC26xx, especially in the file AOA.c?

    Any suggestion?

    Hi,

    In AOA.c, the function AOA_getPairAngles() provides some code to know from which antenna the samples come. You then need to keep track of this information outside the function and send it back to the host PC.

    Now, may I ask why you want to do this? I mean, it will require a significant amount of work and I wonder if it is really needed :)

    Regards,
