Types

type DataRates

type DataRates [16][3]int

DataRates encodes the available datarates of the channel plan for the Station in the format below: [0] -> SF (Spreading Factor; Range: 7...12 for LoRa, 0 for FSK) [1] -> BW (Bandwidth; 125/250/500 for LoRa, ignored for FSK) [2] -> DNONLY (Downlink Only; 1 = true, 0 = false)

type LBSRFConfig

type LBSRFConfig struct {
	Enable    bool   `json:"enable"`
	Frequency uint64 `json:"freq"`
}

LBSRFConfig contains the configuration for one of the radios only fields used for LoRa Basics Station gateways. The other fields of RFConfig (in pkg/pfconfig/shared) are hardware specific and are left out here. - `type`, `rssi_offset`, `tx_enable` and `tx_notch_freq` are set in the gateway. - `tx_freq_min` and `tx_freq_max` are defined in the `freq_range` parameter of `router_config`.

type LBSSX1301Config

type LBSSX1301Config struct {
	LBTConfig           *shared.LBTConfig
	Radios              []LBSRFConfig
	Channels            []shared.IFConfig
	LoRaStandardChannel *shared.IFConfig
	FSKChannel          *shared.IFConfig
}

LBSSX1301Config contains the configuration for the SX1301 concentrator for the LoRa Basics Station `router_config` message. This structure incorporates modifications for the `v1.5` and `v2` concentrator reference. https://doc.sm.tc/station/gw_v1.5.html https://doc.sm.tc/station/gw_v2.html The fields `lorawan_public` and `clock_source` are omitted as they should be present in the gateway's `station.conf`.

func (LBSSX1301Config) MarshalJSON

func (c LBSSX1301Config) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler.

func (*LBSSX1301Config) UnmarshalJSON

func (c *LBSSX1301Config) UnmarshalJSON(msg []byte) error

UnmarshalJSON implements json.Unmarshaler.

type RouterConfig

type RouterConfig struct {
	NetID          []int             `json:"NetID"`
	JoinEUI        [][]int           `json:"JoinEui"`
	Region         string            `json:"region"`
	HardwareSpec   string            `json:"hwspec"`
	FrequencyRange []int             `json:"freq_range"`
	DataRates      DataRates         `json:"DRs"`
	SX1301Config   []LBSSX1301Config `json:"sx1301_conf"`

	// These are debug options to be unset in production gateways.
	NoCCA       bool `json:"nocca"`
	NoDutyCycle bool `json:"nodc"`
	NoDwellTime bool `json:"nodwell"`

	MuxTime float64 `json:"MuxTime"`
}

RouterConfig contains the router configuration. This message is sent by the Gateway Server.

func GetRouterConfig

func GetRouterConfig(bandID string, fps map[string]*frequencyplans.FrequencyPlan, isProd bool, dlTime time.Time) (RouterConfig, error)

GetRouterConfig returns the routerconfig message to be sent to the gateway. Currently as per the basic station docs, all frequency plans have to be from the same region (band) https://doc.sm.tc/station/tcproto.html#router-config-message.

func (RouterConfig) MarshalJSON

func (conf RouterConfig) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler.
