5.4.11 Set-Frequency (03-05)
This command can be used to set frequency at which the reader should operate. It is also possible to specify more
than one frequency. This makes only sense with passive reader. The reader will then be hopping from one to
another frequency. The mode how the reader should hop through the frequencies can also be specified. These
modes are available:
enum HOPPING_MODE (unsigned char)
STATIC_UP 0x00
STATIC_DOWN 0x01
RANDOM 0x02
Every frequency is transferred in three bytes. These three bytes specify the frequency in kHz.
Parameters: HOPPING_MODE mode, unsigned char frequencyCount, unsigned char frequency [frequencyCount]
[3]
Return Values: RFE_RET_VALUE status
Status Values: RFE_SUCCESS, RFE_ERR_ON_EXEC_OP, RFE_ERR_COULD_NOT_WRITE,
RFE_ERR_WRONG_PARAM_COUNT, RFE_ERR_WRONG_PARAM
Example: Set output power to 10 dB
