//      Set up SPP for transmission or reception.
//		Call this function to (re)calibrate the radio, or to switch between
//		different RF settings.
//
//  Arguments:
//      RF_RXTXPAIR_SETTINGS code* pRF_SETTINGS
//			RF settings (frequencies, modem settings, etc.)
//
//      RF_RXTXPAIR_CALDATA xdata* pRF_CALDATA
//			Calibration results
//
//		bool calibrate
//			Calibrate now. *pRF_CALDATA is written to when calibrate = TRUE,
//			and read from otherwise. Use FALSE if *pRF_CALDATA is valid.
