有RSSI,NOISE,REMOTE RSSI和REMOTE NOISE四个动态数据。只要双方的RSSI都明显高于NOISE,就不会丢,还可以预期的遥控距离,参照下文:
To determine what your range would be, a rough rule of thumb is to subtract the ‘rssi’ and ‘noise’ numbers, then divide by 2. That tells you your “fade margin” in decibels. For each 6dB of fade margin your range doubles. So if you have 18dB of fade margin, then you will be able to do roughly 8x whatever range you were at when you measured the margin.

可惜,X宝卖家的东西太烂,两个天线的芯子都脱焊了,RSSI严重下降...准备买手机天线装上。
