ESP32 Wireless Call buttons with Receiver

[Yuvaraj1867]

Hi,

I am planning to do a project named wireless call buttons. This project has two main devices. One is Button(esp32) and another one is receiver(esp32). This buttons are going to implement in patient rooms in a hospital. The receiver is kept in one corner. When the patient press button, the receiver has to receive message from the specific button.

May i know is this possible with ESP, because every floor in hospital has more than 10 rooms and the distance between Room No:10(button10) and receiver will be 200 meters. It may not line of sight also. In my case we should not use internet.

We can do it by station and AP mode, but my doubt is how 200 meters is possible in this case and how many maximum ap(esp32-button) i can connect with one station(esp32).

You could perhaps look at the ESP mesh project if your concern is the distance between the farthest ESP32s in the network, but if there are some ESP32s in between that perhaps could relay the signal/
