nodeMCU seems to reboot when opening web-UI

Hi, i have an issue with a DEBO JT nodeMCU ESP32 flashed with Sound Reactive v013-b4. I connected 30 LEDs long strip WS2812B to GPIO13. No micro added until now. No usermods.

If i open the web-ui the nodeMCU seems to interrupt or even reboot. The web interface drops the red “connection to light failed” - but after a short time everything runs as expected.

While monitoring the connection with ping i can observe that the ping connection is hold for a few seconds.

This happens always on the first access to the Web-UI

Any ideas what could be wrong ?


You should compile with debug enabled and monitor serial output.
Only then it will be possible to diagnose what’s happening.
