TI中文支持网我问想问一下，关于CC2530抓上来的RSSI的值是否是经过硬件或者软件滤波的数据？是否只是针对一次通讯来抓取的数据？另外是否有可能将此RSSI作为判断两节点距离的依据，是否有该类产品。最后关于ZIGBEE定位的应用，现在是否有做的好的产品，精度可以到多少？
Yue TANG：
Datasheet 23.10.3有对RSSI的说明
There are two ways the radio can update the RSSI register after it has first become valid. IfFRMCTRL0.ENERGY_SCAN = 0 (default), the RSSI register contains the latest value available, but if this bitis set to 1, a peak search is performed, and the RSSI register contains the largest value since the energyscan was enabled.
之前zigbee定位有CC2431,硬件定位引擎，但目前NRND,不推荐。RSSI is not really reliable for location.
You must have enough reference point to have a good accuracy.
