// (part-1) esp8266 : 'postman' (the esp-now network nodes)
//
// this module will be an esp-now node in a group.
// like, a bird in a group of birds.
//
// esp-now @ esp8266 DO support broadcast address (FF:FF:FF:FF:FF:FF)
// w/ NONOS-SDK of espressif
// and you can enable that w/ Platformio, applying some special build flags.
// --> https://github.com/esp8266/Arduino/issues/6174#issuecomment-509115454
// (yet, w/ Arduino, this is not available yet.)
//
// so, at first, we will simply/stably go w/o broadcasting.
// and, if broadcast is really needed we can activate (@Platformio)
//
// then, let is save a value in EEPROM (object with memory)
// no broadcast for now. if needed we can achieve that too.
//==========<configurations>===========
//
// 'HAVE_CLIENT'
// --> i have a client. enable the client task.
//
// 'SERIAL_SWAP'
// --> UART pin swapped.
// you want this, when you want a bi-directional comm. to external client boards (e.g. teensy).
//
// 'DISABLE_AP'
// --> (questioning)...
