1.2.7.4.2 SRV_RSNIFFER_SerialRxMessage Function

C

uint8_t* SRV_RSNIFFER_SerialRxMessage (
    DRV_RF215_RX_INDICATION_OBJ* pIndObj,
    DRV_RF215_PHY_CFG_OBJ* pPhyCfgObj,
    uint16_t paySymbols,
    uint16_t channel,
    size_t* pMsgLen
);

Summary

Serializes a received RF frame along with its parameters.

Description

This function takes an object containing a RF frame and its related parameters and serializes it in a buffer for further transmission through serial interface.

Precondition

None.

Parameters


Param	Description
pIndObj	Pointer to RF reception object containing the frame and parameters
pPhyCfgObj	Pointer to RF PHY configuration object
paySymbols	Number of payload symbols in the received frame
channel	RF channel used to receive the message
pMsgLen	Pointer to sniffer message length in bytes (output)

Returns

Pointer to sniffer message to be sent through serial interface.

Example

DRV_HANDLE drvRf215Handle; // returned from DRV_RF215_Open
SRV_USI_HANDLE srvUSIHandle; // returned from SRV_USI_Open

static void _APP_RfRxIndCb(DRV_RF215_RX_INDICATION_OBJ* ind, uintptr_t ctxt)
{
    DRV_RF215_PHY_CFG_OBJ rfPhyConfig;
    uint8_t* pRfSnifferData;
    size_t rfSnifferDataSize;
    uint16_t rfPayloadSymbols;
    uint16_t rfChannel;

    // Get payload symbols in the received message
    DRV_RF215_GetPib(drvRf215Handle, RF215_PIB_PHY_RX_PAY_SYMBOLS,
            &rfPayloadSymbols);

    // Get RF PHY configuration
    DRV_RF215_GetPib(drvRf215Handle, RF215_PIB_PHY_CONFIG, &rfPhyConfig);
    DRV_RF215_GetPib(drvRf215Handle, RF215_PIB_PHY_CHANNEL_NUM, &rfChannel);

    // Serialize received RF message
    pRfSnifferData = SRV_RSNIFFER_SerialRxMessage(ind, &rfPhyConfig,
            rfPayloadSymbols, rfChannel, &rfSnifferDataSize);

    // Send through USI
    SRV_USI_Send_Message(srvUSIHandle, SRV_USI_PROT_ID_SNIF_PRIME,
            pRfSnifferData, rfSnifferDataSize);
}

Remarks

None.
