Hello,
I am planning to have one ESP32(MASTER) connected to another ESP32(SLAVE). Can I have such setup ?
If yes, how to get the master trigger the slave to do some task ?
Appreciate any leads or examples

Thanks

How are the 2 esp32 conneted?
UART, WiFi, Bluetooth or??
any way you will have to write the programs to run on the esp32s.

What do you want to achieve? Give us more details please.
You can connect two analog pins (and ground) together, set 1 pin to high and the other to low, check for state changes to trigger your task. Or you can setup a client server/server HTTP, and send data across. Or connect via serial ports to send data, or Bluetooth or Ethernet...
