AOA为何将Master和passive分开成两个部分？这样做的目的是什么？

标准的AOA方案只有Master和Slave，其中Master 带有天线阵列。而你们的方案是新增了一个带有天线阵列的passive，master不再带天线阵列。使用的时候也是mater和slave建立连接，然后passive相当于一个抓包工具，具有接受CTE包和IQ采样的功能。所以有点不理解为何将master与天线阵列拆开而新增一个passive，这样做的目的是什么呢？

Alvin Chen：

RTLS Passive
The RTLS passive does not actively participate in the BLE connection between the RTLS master and slave. Instead, it uses the Micro BLE-Stack in connection monitoring mode to follow the connection. To do this, the passive device relies on the Master to distribute the connection parameters once a connection is formed. The passive node does the following:

Implement ToF passive role
Receives packets with CTE and performs in-phase and quadrature component (IQ) sampling
Uses Micro BLE-Stack in Connection Monitoring mode to follow connection between master and slave

我现在清楚和明白passive的作用和功能，简单的说就是标准的AoA只需要两个板子，而你们的需要三个板子，实际应用中成本肯定是比较高的，所以想知道使用三种角色的板子的优势是什么？
