Functions

func NewBackend

func NewBackend(redisPool *redis.Pool, c Config) (backend.Gateway, error)

NewBackend creates a new Backend.

Types

type Backend

type Backend struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

Backend implements a MQTT pub-sub backend.

func (*Backend) Close

func (b *Backend) Close() error

Close closes the backend. Note that this closes the backend one-way (gateway to backend). This makes it possible to perform a graceful shutdown (e.g. when there are still packets to send back to the gateway).

func (*Backend) DownlinkTXAckChan

func (b *Backend) DownlinkTXAckChan() chan gw.DownlinkTXAck

DownlinkTXAckChan returns the downlink tx ack channel.

func (*Backend) RXPacketChan

func (b *Backend) RXPacketChan() chan gw.UplinkFrame

RXPacketChan returns the uplink-frame channel.

func (*Backend) SendGatewayConfigPacket

func (b *Backend) SendGatewayConfigPacket(configPacket gw.GatewayConfiguration) error

SendGatewayConfigPacket sends the given GatewayConfigPacket to the gateway.

func (*Backend) SendTXPacket

func (b *Backend) SendTXPacket(txPacket gw.DownlinkFrame) error

SendTXPacket sends the given downlink-frame to the gateway.

func (*Backend) StatsPacketChan

func (b *Backend) StatsPacketChan() chan gw.GatewayStats

StatsPacketChan returns the gateway stats channel.

type Config

type Config struct {
	Server                string
	Username              string
	Password              string
	QOS                   uint8  `mapstructure:"qos"`
	CleanSession          bool   `mapstructure:"clean_session"`
	ClientID              string `mapstructure:"client_id"`
	CACert                string `mapstructure:"ca_cert"`
	TLSCert               string `mapstructure:"tls_cert"`
	TLSKey                string `mapstructure:"tls_key"`
	UplinkTopicTemplate   string `mapstructure:"uplink_topic_template"`
	DownlinkTopicTemplate string `mapstructure:"downlink_topic_template"`
	StatsTopicTemplate    string `mapstructure:"stats_topic_template"`
	AckTopicTemplate      string `mapstructure:"ack_topic_template"`
	ConfigTopicTemplate   string `mapstructure:"config_topic_template"`
}

Config holds the MQTT backend configuration.
