IWR6843ISK-ODS: how to apply radar cube data to DOAin for "68xx AoP_ODS - Multiple Gesture and Motion Detection"

Dear support team,

Let me raise a question related to below thread ;

IWR6843ISK-ODS: TX used in angle estimation in gesture.c - Sensors forum - Sensors - TI E2E support forums

According to the CLI command, 1st chirp is generated by Tx3 and 2nd one is by Tx2.

In this case, we suppose the rader cube data should be arrayed as below ;

         * ch-4   ch-7  (Tx2)

         * ch-5   ch-6  (Tx2)

         * ch-0   ch-3  (Tx3)

         * ch-1   ch-2  (Tx3)

  So, we suppose those data should be applied to DOAin as below ;

              gDOA2D[0][0] = DOAIn[4];

              gDOA2D[0][1] = DOAIn[7];

              gDOA2D[1][0] = DOAIn[5];

              gDOA2D[1][1] = DOAIn[6];

              gDOA2D[2][0] = DOAIn[0];

              gDOA2D[2][1] = DOAIn[3];

              gDOA2D[3][0] = DOAIn[1];

              gDOA2D[3][1] = DOAIn[2];

This is different from your source code in mulit_gesture_68xx_ods_dss/dss/gesture.c. Please kindly advise if our idea is not correct.

Best regards,
