Types

type Config

type Config struct {
	MAC     string `json:"mac"`
	Keys    `json:"keys"`
	Devices []Device `json:"devices"`
}

type Device

type Device struct {
	Addr   string `json:"addr"`
	DevEUI string `json:"dev_eui"` // nolint: tagliatelle
}

type Gateway

type Gateway struct {
	Config
}

Gateway simulate data based on LoRaWAN protocol from an ABP device and one gateway. It encrypts data and you will need a lora server to decode it.

func New

func New(cfg Config) Gateway

create new gateway simulation based on given configuration.

func (Gateway) Generate

func (g Gateway) Generate(message interface{}, index int) ([]byte, error)

Generate generates lora message by converting input into cbor and encrypts it. nolint: funlen

func (Gateway) Topic

func (g Gateway) Topic() string

Topic returns lora gateway mqtt topic.

type Keys

type Keys struct {
	NetworkSKey     string `json:"network_skey"`     // nolint: tagliatelle
	ApplicationSKey string `json:"application_skey"` // nolint: tagliatelle
}
