dutycycle

type BestTarget ¶

type BestTarget struct {
	ID    int  // The ID provided during updates
	IsRX2 bool // Whether it should use RX2
}

BestTarget represents the best result that has been computed after all updates.

type Cycles ¶

type Cycles map[subBand]uint32

Cycles gives a representation of sub-band usages

type DutyManager ¶

type DutyManager interface {
	Update(id []byte, freq float32, size uint32, datr string, codr string) error
	Lookup(id []byte) (Cycles, error)
	Close() error
}

DutyManager provides an interface to manipulate and compute gateways duty-cycles.

func NewManager(filepath string, cycleLength time.Duration, r region) (DutyManager, error)

type ScoreComputer ¶

type ScoreComputer struct {
	// contains filtered or unexported fields
}

ScoreComputer enables an external component to manipulate metadata associated to several targets in order to determine which target is the most suitable for a downlink response. It considers two windows RX1 and RX2 with the following conventions:

For SF7 & SF8, RX1, the algorithm favors RX1

For SF9+ or, if no target is available on RX1, then RX2 is used

Within RX1 or RX2, the SNR is considered first (the higher the better), then the RSSI on a lower plan.

func NewScoreComputer(datr string) (*ScoreComputer, scores, error)

func (c *ScoreComputer) Get(s scores) *BestTarget

func (c *ScoreComputer) Update(s scores, id int, metadata core.Metadata) scores

type State ¶

type State uint

State Refers to an actual State of a transmitter

const (
	StateHighlyAvailable State = iota
	StateAvailable
	StateWarning
	StateBlocked
)

func StateFromDuty(duty uint32) State
