GUI-O <> Wi-Fi Esp32 Wroom
I was looking for a small example of how to use Gui-O to communicate with Esp32 Wroom via Wi-Fi. I've already done an example with BLE, but now I'd like to use Wi-Fi communication without Internet.
Does anyone have a small example to share?
What do you mean without Internet? You want only local connection, i.e. LAN?
that is, without internet.
I have allready make a prototype function with BLE, it works good, but now want local using
Wi-Fi between Gui-O and Esp32, it is possible?
@Sato You could create a closed network - a router that does not connect to the internet. You can use Ethernet connection example:
Note that this connection does not use encryption, but since it is a closed network it should be ok. Provide a strong password for your router.
You could alternatively setup a mosquitto broker using a PC connected to the isolated router. Or you could probably even run a broker on ESP32... This involves far more effort though.
