根据提供的官方文档,Passive(CC26X2外接BOOSXTL天线阵列)测量的是与Slave测量的角度,我想问的是具体是指哪两块,是指由Slave射向Passive外接天线阵列的角度吗?如果是这样,我在进行如下实验时,测得的角度与实际两个天线摆放的角度产生了角度误差,如附件所示:上面为Slave,下面为Passive,读出的角度是较为稳定的40°左右,这个与摆放位置的角度明显有差别,所以我想问下是什么原因导致的。

定位的是从设备,另外对环境要求比较高,按下面的设置测一下
Before evaluating the RTLS solution, it is important to consider the environment. All radio communication protocols can be susceptible to multi-path fading, and RTLS based systems are not exempt. It is important to control the environment when evaluating or at least be aware of the potential effects of multi-path on the results.
It is recommended to evaluate the RTLS solution in an area that optimizes RF conditions. This includes:
- An open space with no large metal or concrete obstructions (pillars, poles, etc)
- Relatively few interference sources (i.e. Wi-Fi access points, etc)
- Raised platforms for the nodes made out of cardboard ~1 m off the ground.
A desk environment generally has sub-optimal RF conditions and should be avoided.
