3.2.2 - Selection of the RF medium physical mode
The available physical layer modes, are :
•
868 MHz single channel 4800 baud,
•
868 MHz single channel 4800 bauds Alarm Band,
•
868MHz single channel 9600 bauds with channel selection,
•
868 MHz frequency hopping 9600 baud,
•
868 MHz frequency hopping 19200 baud,
•
869MHz 500mW Band (for Wavecard 25mW radio board, this mode is supported but the
emission power is limited).
It is possible to modify the physical layer mode via requests of reading, and writing. The commands are as
follow,
