ESPNOW is a kind of WiFi communication bettween WiFi devices, no
matter they are connected to each other or not. Once two WiFi
devices are paired, they can send data to or receive data from
each other. The data is transmitted in action frame which can
be encrypted with CCMP method. ESPNOW also support mutilcast frame
transmitting.
