3.3.10. MbusLinkTransmitFrame

Prototype:

LINK_STATUS MbusLinkTransmitFrame(__in Frame* frame);

Parameters:

frame—A pointer to a LINK frame specifying the C, M, A, CI, and Data fields

Returns:

LINK_STATUS_SUCCESS

LINK_STATUS_PHY_ERROR_INVALID_VALUE

LINK_STATUS_PHY_ERROR_INVALID_STATE

LINK_STATUS_PHY_ERROR_INVALID_LENGTH

LINK_STATUS_PHY_ERROR_POR_TIMEOUT

LINK_STATUS_PHY_ERROR_XTAL_TIMEOUT

LINK_STATUS_PHY_ERROR_UNSUPPORTED_RADIO

LINK_STATUS_PHY_ERROR_TX_TIMEOUT

LINK_STATUS_INVALID_SIZE

Description:

This function takes a frame input and generates a frame buffer consisting of L, C, M, A, CI, Data, and CRC fields

(stored in an internal TX frame buffer). The L and CRC fields are automatically calculated and added to the frame

buffer. If the EZRadioPRO is not already in IDLE mode, this function will call MbusLinkRadioConfig(). This allows

users to optimize power usage by generating a transmit frame while initializing the EZRadioPRO. Next, the

function transmits the frame buffer via the PHY.

3.3.11. MbusLinkTransmitFrameAtTime

Prototype:

LINK_STATUS MbusLinkTransmitFrameAtTime(__in U32 txRtcTime, __in Frame* frame);

Parameters:

txRtcTime—The time in RTC (32.768 kHz) ticks at which to transmit the frame

frame—A pointer to a LINK frame specifying the C, M, A, CI, and Data fields

Returns:

LINK_STATUS_SUCCESS

LINK_STATUS_PHY_ERROR_INVALID_VALUE

LINK_STATUS_PHY_ERROR_INVALID_STATE

LINK_STATUS_PHY_ERROR_INVALID_LENGTH

LINK_STATUS_PHY_ERROR_POR_TIMEOUT

LINK_STATUS_PHY_ERROR_XTAL_TIMEOUT

LINK_STATUS_PHY_ERROR_UNSUPPORTED_RADIO

LINK_STATUS_PHY_ERROR_TX_TIMEOUT

LINK_STATUS_INVALID_SIZE

Description:

This function takes a frame input and generates a frame buffer consisting of L, C, M, A, CI, Data, and CRC fields

(stored in an internal TX frame buffer). The L and CRC fields are automatically calculated and added to the frame

allows users to optimize power usage by generating a transmit frame while initializing the EZRadioPRO®. Next,

the function transmits the frame buffer via the PHY at the specified RTC time.
