typedef struct txContextConfig_tag
{
bool_t ccaBeforeTx;
bool_t autoAck;
uint8_t retryCountCCAFail;

}txContextConfig_t;
Members
ccaBeforeTx
bool_t value to enable/disable the “LBT” mechanism.
autoAck
bool_t value to enable/disable the “AA” mechanism.
retryCountCCAFail
This value specifies the number of times the MKW01 SMAC will
attempt to re-transmitt a packet if “LBT” is enabled and channel is found
busy.
retryCountAckFail
This value specifies the number of times the MKW01 SMAC will
attempt to re-transmitt a packet if “AA” is enabled and no
acknowledgement message is received in the expected time frame.

} smacTestMode_t;
This enumeration is used only in the Connectivity Test Application, to select the type of test to be
performed. Keep in mind that all the decisions are taken at application level and this enumeration is used
only as a reference for designing the test modes.
