I understand that the esp8266 can operate as either a Station, Access Point or both. Which I get.

However when the terms Server and Client are also brought into the mix, I am somewhat confused. Can Stations and Access Points operate as both clients and servers (or both)?


AP/STA and Client/Server refer to different protocol layers so are theoretically independent but its more likely that you will find servers on AP's and clients on STA's.

This is not to say it cant be done the other way round, just that its not usual...
