Hello forum. A beginner question

[Need2learn]

Hi all.Much respect for the forum. I introduce myself I am need2learn, new in this world. I have an idea and to continue with the development, I would like to know how many esp32 clients I can connect through 1 server esp32.

I believe the IDF supports up to 7 connections. It is an option the the "make menuconfig"

Thanks for the info etha890. I need to connect 16 units(clients) of Esp32 to a server that collects the info and sends it by gsm text messages. I only collect information of the esps: switch open or closed. How could i do it?

I believe we have small misunderstanding here. I think you are asking about connecting many esp32 in general, but above answer narrows it to ble only.
You have other options too. WiFi mesh, ble mesh (beta version so far), http server and http clients etc. With each protocol you can connect dozens and don't forget about i2c slave/master.

How often does each client need to update the state of its switch? Unless these switches are toggling very quickly/frequently, you might be able to get away with just disconnecting after updating the server, then idling until the switch changes state again.
