Re: Slow response from ESP32-S2 Webserver

The problem has been solved by adding a delay(1) in handleClient() or loop(): https://github.com/espressif/arduino-es ... -695115885

Re: Slow response from ESP32-S2 Webserver

Another thing I've tried: Adding a 100nF capacitor on the 3.3V net And I just discovered that if I don't connect my browser to the webserver after resetting, the ping response times look better than on my ESP-12F: 64 bytes from 192.168.0.29: icmp_seq=61 ttl=255 time=2.37 ms 64 bytes from 192.168.0.2...

It only works when letting DHCP choose the IP address...

Re: WS2815 and ESP32

Did you add a 1000uF electrolytic capacitor to each strip? If not, try it. Often this helps with WS2812B, so it may help with these strips too.

Slow response from ESP32-S2 Webserver

Using the HelloServer.ino example on a ESP32-S2 Wrover I get slow responses when pointing my browser at the ESP32-S2 IP address. A similar server (with ESP8266 default libraries) running on an ESP-12F has reasonable response times. According to the network request monitor in Firefox, connecting take...
