蓝牙搜不到，抓到广播包发现FCS错误

蓝牙搜不到，抓到广播包发现FCS错误。请问是什么原因呢？谢谢

借鉴下国外工程师的答案：

Keep in mind that when you see an "FCS error" on the packet sniffer, it could be that the BLE communication between the two devices is actually good, and the sniffer just misread bits when sniffing.

In general these can occur if you have a noisy environment or if there is something physically degrading the signal on the board. You can use software such as SmartRF Studio to verify the RF performance of your board.
