Laut dem was in dem Datenblatt steht:

Any other Easy-Radio Transceiver within range that hears the transmission will decode the message and place the recovered data within a receive buffer that can then be unloaded to the receiving host for processing and interpretation. Transmission and reception are bi-directional half duplex i.e. transmit OR receive but not simultaneously.
Müsste das aber ohne Probleme gehen...oder
