I send OSC message with an LFO. (I send a float from 0.0 to 1.0)
I can see in the monitor of IDE Arduino, that message is not perfectly received
So the light of build in is not synchronized too.
I use my USB port as power supply. My esp32 is the Heltec Wifi 32 V3
I'm quite sure that I managed once to have a regular flashing...
Thank for trying to give me a direction
Here my code with fastLed library

Example for receiving open sound control (OSC) messages on the ESP8266/ESP32
Send integers '0' or '1' to the address "/led" to turn on/off the built-in LED of the esp8266.
