// FARM DATA RELAY SYSTEM

|

// Example sketch to provide several examples to obtain and use time
|
||||
// from a gateway
|
||||
// This sketch retrieves the time from a nearby FDRS gateway using ESP-NOW.
|
||||
// After retrieving the time, at 60 second intervals, it prints out each field of the time
|
||||
// in two different methods.
