• 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,
CMD NA ME DE SCRIPTION
0x64 REQ_SELECT_PHYCONFIG Request to select the RF medium physical mode
0x65 RES_SELECT_PHYCONFIG Response to the physical mode selection request
0x66 REQ_READ_PHYCONFIG Request to read the RF medium physical mode
0x67 RES_READ_PHYCONFIG Response to the physical mode reading request
Remark : In the command byte coding, the Response frame type are taking the Request command
byte value with the LSB bit set to 1.
