CC2640R2F AOA 信道频率

您好 

   请问在AOA计算角度过程中,

   1、每次传输CTE数据包的信道都是不同的 ,对吗?

   2、这个信道切换是一个函数控制的?

   3、在这个CTE数据包头部信息已经包含了信道信息,我们可以根据这个信息直接查表获取相应的信道频率,如果是这样我能在蓝牙源码中找到这个表吗?

   谢谢!

    The Constant Tone Extension is only enabled when the CP bit in the Data Physical PDU header is set. The detail of the Constant Tone Extension is then specified by the CTEInfo field in the in the Data Physical PDU.

    关于CTE的捕获,例程中有相关的API
