Variables

var ClassBEnqueueMargin = time.Second * 5

ClassBEnqueueMargin contains the margin duration when scheduling Class-B messages.

var MulticastClassCInterval = time.Second

MulticastClassCInterval defines the interval between the gateway scheduling for Class-C multicast.

var SpreadFactorToRequiredSNRTable = map[int]float64{
	6:  -5,
	7:  -7.5,
	8:  -10,
	9:  -12.5,
	10: -15,
	11: -17.5,
	12: -20,
}

SpreadFactorToRequiredSNRTable contains the required SNR to demodulate a LoRa frame for the given spreadfactor. These values are taken from the SX1276 datasheet.

var Version string

Version defines the LoRa Server version.
