CC2640R2F: AOA angle not change

Viki Shi

Part Number: CC2640R2F

Hi Team,

My customer set up the AOA environment as our document shows. With the original example in SDK 3.30,the angle was jumping and fluctuating a lot. After he modified to use only two antennas, the angle only showed 5.6.7 values no matter how he moved the slave board. Whether the BOOSTXL-AoA plugged or not, it always got the same value. Which looked like the antenna was not working.

SDK version: 3.30 [Also tested on 3.20, same result]

HW: TI board

Best Regards,

Hi,

From the symptoms you are describing (same behavior wit or without booster pack, same behavior with several SDK), I am wondering if the capacitor C51 has been correctly set. Can you verify this with your customer please?

You will find the details in the getting started guide of the BOOSTXL-AoA (here), in the "Preparations" section.

Best regards,
