蓝牙AOA的IQ数据是否有误



hi,我使用BOOSTXL-AOA作为master,用cc2652作为slave,建立connectionless连接。用sdk自带的rtls_connectionless_aoa_example_with_rtls_util.py来记录原始的IQ数据,sdk版本为simplelink_cc13x2_26x2_sdk_4_40_00_44。

以下是根据上传的IQ数据用atan2函数求相位后绘制出的相位图,发现相位是由180逐渐减到-180,而按照https://dev.ti.com/tirex/explore/content/simplelink_academy_cc2640r2sdk_3_30_01_00/modules/rtls_toolbox_ble3/ble_aoa/ble_aoa.html#introduction中TASK 5所述,相位点应该从-180开始变化到180。并且我根据你们提供的算法由IQ值计算PairAngle,发现计算出的数据与真实值确实是差了一个负号,是相反数关系。请问是IQ数据的问题还是我计算过程有误?
