There are drivers out there on Linux that have in the past, or currently, only support monitor. Installed base of CircuitPython ESP32-S2 code is based around STA. 11 Wi-Fi packets. If so, then, even if the adapter and the OS driver for the adapter support promiscuous mode, you might still not be able to capture all traffic, because the switch won't send all traffic to your Ethernet, by default. The advantage of operating in Promiscuous mode is that the Sensor does not affect the packet flow with the forwarded traffic. Promiscuous mode allows either a wired network interface controller or a wireless network interface controller to hand all of the packets it receives over to the CPU. I believe there is a bug in the WiFi promiscuous mode packet receiving code in IDF v4.
