Expected behavior

ESP32-C6支持WiFi 6协议,应该能捕获商用WiFi 6环境中的无线数据包。

Actual behavior (suspected bug)

在实际WiFi 6网络中尝试使用ESP32-C6捕获商用AP与手机之间的下行Data帧,但无论是自己编写的程序还是官方sniffer例程均无法捕获任何下行Data帧,仅能捕获部分低速的管理帧与控制帧。附件内有同期使用WiFi抓包卡抓取的空口数据包。

    从你的抓包文件可以看出,在路由器和手机数据传输时,使用的是 MCS 9,1024-QAM, 3/4 码率, 2 空间流的模式,这超过了esp32C6的通讯能力,因此无法抓包。

    您好,我尝试用ESP32C6和C5 in promiscuous mode去监测环境中的802.11ax(HE)数据包,但从来没有抓取到任何HE数据包,请问这个是咋回事嘛。以下文件是通过电脑抓到的数据包(ESP32C5和C6都不能抓取到这些包),他们都是Qos, MCS <= 9, 但空间流模式(NSTS = 1),符合ESP32C6或者C5的通讯能力要求。
