CC1310: Code snippet to read RSSI

This was very confusing:

static rfc_propRxOutput_t rxStatistics;
int8_t RSSIout;

// Under Modify CMD_PROP_RX command for application needs
RF_cmdPropRx.pOutput = (uint8_t*)&rxStatistics;

// Where you want to read out the RSSI in the code
RSSIout = rxStatistics.lastRssi;

The second line is supposed to be put where? There is no declararation for RF_cmdPropRx anywhere in the workspace

I suspect that I wrote an answer and newer presses reply.

In smartrf_settings.h:
extern rfc_CMD_PROP_RX_t RF_cmdPropRx;

Also, in the rfPacketRX example, search for "Modify CMD_PROP_RX command for application needs" in the rfPacketRx.c file.
