• 868 MHz single channel, 4800 baud
• 868 MHz single channel, 4800 baud alarm band
• 868 MHz single channel, 9600 baud with channel selection
• 868 MHz frequency hopping, 9600 baud
• 868 MHz frequency hopping, 19200 baud
• 869 MHz, 500mW band (Note: this mode is supported on the Waveport CF 25mW radio board,
but transmission power is limited).
• 915 MHz, frequency hopping,19200 baud
You may modify the physical layer mode with read and write requests. The commands for this are:
CMD NAME DESCRIPTION
0x64 REQ_SELECT_PHYCONFIG Request to select RF communication mode
0x65 RES_SELECT_PHYCONFIG Response to communication mode selection request
0x66 REQ_READ_PHYCONFIG Request to read RF communication mode
0x67 RES_READ_PHYCONFIG Response to communication mode read request
In command byte coding, response frames reuse the request command with
the LSB bit set to 1.
