How to use multiple connections on esp modules?

Yeah I should explain more as you said. Tnx for the reply BTW.The wemoses are supposed to send some analog values to the main server on esp32 and then it updates those values on the server so the phones can use those values and show them (I'm not asking anything about Android programming here just wanted to explain more)also some values should be sent from esp32 to esp8266 on the wemoses so they detect a change and change the way themselves work.So the hardware acceptes 16 connection right?What do you mean only one or zero at a time how much time does it take to switch to a new client so?Do you mean the clients get available only when they connect to the esp32 at the first time or with the 16 connection stablished I still can switch between clients and receive and send data?
Tnx.
