CC3220SF-LAUNCHXL: 使用CC3220进行时间同步

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: AWR1642BOOST, AWR1642
问题描述:目前有两块AWR1642BOOST(一种毫米波雷达开发板),同步需求是需要让两块开发板发射天线发送脉冲的时候脉冲起始时间对齐。已经实现了有线同步,即用一个外部触发源通过上升沿触发的方式同时触发两开发板。但是现在需要无线同步,如下图所示,想寻求一种设备能具备图中紫色框中模块的作用
e2e工程师建议如下:I am not an expert in wireless communication domain, but you could look at using WiFi devices like CC3220 that could be used to sync. The two wifi devices connected to the AWR1642 devices could be synced over air and they could toggle a GPIO to HW trigger the AWr1642 frames. 
由于我之前没有接触过TI的WiFi系列开发板,所以想请问两个问题:1.使用CC3220进行图中所示的时间同步的配置复杂吗?  2.使用CC3220最高能达到多高的时间同步精度?
