Delayed ping response
Posted: Mon May 11, 2020 1:06 am
Hi.
I'm looking into the response of the ESP32's WIFI.
Using the example in esp-idf/examples/wifi/getting_started/station, I connected the ESP32 Devkit4 to the AP. I ran ping -i 0.2 192.168.0.160 from an Ubuntu machine (18.04LTS) connected to the AP, and here's the result.
The average is about 1-4ms, but sometimes there is a delay of 10-20ms.
Do you know what caused it? This problem also arises in other examples of using WIFI.
