It works great so far.
Un exemplo muy bueno. Lo hice usando un M5NanoC6 con WiFi, NTP y un sensor the movimiento para prender las luces en la noche a specific time. Muchas gracias.

Hi.
You can use Wi-Fi at the same time.
I already did that using Arduino IDE.

I haven’t tried it using with MicroPython. But, I believe it should also work, but I’m not sure if there are any specific configurations that need to be made.

Regards,
Sara

with this protocol can the wifi still active on the board.
to send sent from on to another ESP32 than take this data threw the internet?
or this protocol block wifi on the board??

Sorry, ignore me – I now see this tutorial is about a different comms protocol so my question is irrelevant!

Hi.
It depends on the surrounding environment and also on the ESP32 board models you’re using.
If you’re in open-field the distance you’ll be longer. With the ESP32 DevKIT DOIT, we got around 250meters.
If you’re in a city with lots of buildings, the distance will be shorter.
Regards,
Sara

How much extra work would it be to make this 2 way communication work with device 2 being in a remote location on another network?
