Hallo,
ich habe mich schon durch das Forum gelesen aber noch keine richtige ASntwort erhalten. 
Aufbau
Ein Arduino Nano sendet Daten an einen anderen Arduino Nano - beide Module sind per Pin2 (Interrupt 0) angeschlossen. Beim Senden mit Arduino 1 leuchtet die TX LED kurz auf, RX-LED bei Arduino 2 jedoch nicht. Arduino 2 gibt auch keine Daten per serieller Konsole aus. Versorgungsspannung an beiden Module n i.O.
verwendetes Modul:
FS1000A mit angelötetet Drahtantenne
Anbei der Code vom Sender:
