-//
-//   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.

-//           (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)
-//
-
-
-// we want to first osc -> esp-now
-// then, esp-now based taak
-// then, let is save a value in EEPROM (object with memory)
-// no broadcast for now. if needed we can achieve that too.
