Questions
1

I am thinking of connecting and syncing two esp32s in a place without wifi router. What configuration should I use? Should it be:

  1. Set Master to AP mode
  2. Connect Slave to Master’s AP
    Is this correct?
    Thanks!

Yes. You could also use the new, esp-now.

Alpha version of 0.15 (unreleased yet) offers sync over ESP-NOW.
Same principles as regular UDP sync except no WiFi required.

Do you know if using ESP-now is faster and more likely to be in sync than wifi if the devices are close together?

5

Very much more likely to be in sync as the only WiFi devices that use ESP-Now are - ESP.
Your, laptop, cellphone, tablet, etc. don’t affect the ESP-Now traffic, which is not the case for standard WiFi.

Best way to test it.
