NFC_CX_RF_DISCOVERY_CONFIG structure (nfccx.h)
The NFC_CX_RF_DISCOVERY_CONFIG structure contains RF discovery configuration settings. Discovery configuration should be completed during initialization after calling NfcDxDeviceInitialize, otherwise an error is returned.

Members
Size
Size of this structure in bytes.
TotalDuration
Total duration of the single discovery period in milliseconds. Default is 300 milliseconds.
This member corresponds to TOTAL_DURATION specified in the NCI specification. Values can be between 0 to 0xFFFF. Use an appropriate value that factors into account both the discovery latency as well as power consumption.
PollConfig
Combination of NFC_CX_POLL_MODE_CONFIG values.
This member enables configuration of poll mode settings. The default enables polling for passive poll NFC-A, passive poll NFC-B, and passive poll NFC-F (212 and 424k). Its recommended that NFC clients configure additional active modes if they are supported.
NfcIPMode
Combination of NFC_CX_NFCIP_MODE_CONFIG values.
This member enables configuration of NFC-IP initiator mode settings. The value corresponds to combination of NFC_CX_NFCIP_MODE_CONFIG enum. The default enables polling for passive poll NFC-A and passive poll NFC-F (212 and 424k) phases.
NfcIPTgtMode
Combination of NFC_CX_NFCIP_TGT_MODE_CONFIG values.
This member enables configuration of NFC-IP target mode settings. The default enables passive listen NFC-A and passive listen NFC-F phases.
NfcCEMode
Combination of NFC_CX_CE_MODE_CONFIG values.
This member enables configuration of NFC-CE mode settings. The default enables passive listen NFC-A, passive listen NFC-B, and passive listen NFC-F phases.
BailoutConfig
Combination of NFC_CX_POLL_BAILOUT_CONFIG values. Default is disabled.
This member enables configuration of PA_BAIL_OUT and PB_BAIL_OUT as described in the NCI specification.
