 You can transfer data between two RF-Bees, i.e. one on the Stalker (or another Arduino), the other at the receiving gateway (server, PC, Raspberry PI, ...).

 The small Arduinos based on ATmege328 (Arduino Uno, Seeeduino Stalker, ,...) just have one UART which by default is used for the USB connection, e.g. when using something like Serial.print("Hello");
-The workaround is a so-called soft-UART, (library softserial), an emulated UART in software. The performance of a soft UART is limited, but it can help to connect another UART device such as RF-Bee to the Arduino.

 There are two bugs concerning the connection of any Bee module to the Stalker pins to use software serial. The following connections have to be established to use the Bee module with a software serial port (UART emulated in software, library softserial.h):
