I'm trying to use ESP32 boards as wireless receivers in a musical context where timing is critical, but when sending data via OSC the timing is all over the place (the click sound is generated by the PC that is sending the OSC via Wifi, showing the offset with the LED timing). Any ideas for a fix?
i didn't know you're sending notes too, ok. either send all notes together or only the very imminently next note might suffice. i was sceptical about the accuracy of NTP, supposedly most libraries have an accuracy of 1second, but this particular library is supposed to reach accuracies in the milisecond range, that should work. https://github.com/gmag11/ESPNtpClient basically sending one note with NTP time in the future and wait until that times has passed ( + 20ms?), then send next note.

Delonghi "indecent" espresso machine
The v1 hardware PCBs are in this repo https://github.com/cs2dsb/coffee_assistant if you want to look at it for inspiration but there are a bunch of faults I need to fix (transistors rotated incorrectly for 1, which is a real bonehead mistake.)

wifi and esp-now.... again!
I've got examples of this working: node and bridge. Those examples are self contained - I later refactored it so it's all in now.cpp which may be more useful if you want to use it as a library but probably less easy to read/understand.

Here's a complete sketch that works and calls it: esp-now-bridge-test.ino

ESP NOW library issues
WiFi "bridge"
-
Did anyone successfully solved the problem of collecting sensor reports using ESP-NOW and forwarding the data via WiFi client?
I just committed a version that works with deep sleep using RTC and EEPROM to stash the channel and bridge mac.
