Functions ¶
func New ¶
func New(opts ...TransportOption) transport.Transport
New returns new Transport transport. See more: https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-mqtt-support
func NewModuleTransport ¶
func NewModuleTransport(opts ...TransportOption) transport.Transport
New returns new Transport transport. See more: https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-mqtt-support
Types ¶
type ModuleTransport ¶
type ModuleTransport struct {
Transport
// contains filtered or unexported fields
}
func (*ModuleTransport) Connect ¶
func (tr *ModuleTransport) Connect(ctx context.Context, creds transport.Credentials) error
func (*ModuleTransport) SubscribeEvents ¶
func (tr *ModuleTransport) SubscribeEvents(ctx context.Context, mux transport.MessageDispatcher) error
type Transport ¶
type Transport struct {
// contains filtered or unexported fields
}
func (*Transport) RegisterDirectMethods ¶
func (*Transport) RetrieveTwinProperties ¶
func (*Transport) SubscribeEvents ¶
func (*Transport) SubscribeTwinUpdates ¶
type TransportOption ¶
type TransportOption func(tr *Transport)
TransportOption is a transport configuration option.
func WithClientOptionsConfig ¶
func WithClientOptionsConfig(fn func(opts *mqtt.ClientOptions)) TransportOption
WithClientOptionsConfig configures the mqtt client options structure, use it only when you know EXACTLY what you're doing, because changing some of opts attributes may lead to unexpected behaviour.
Typical usecase is to change adjust connect or reconnect interval.
func WithLogger ¶
func WithLogger(l logger.Logger) TransportOption
WithLogger sets logger for errors and warnings plus debug messages when it's enabled.
func WithModelID ¶
func WithModelID(modelID string) TransportOption
WithModelId makes the mqtt client register the specified DTDL modeldID when a connection is established, this is useful for Azure PNP integration.
func WithWebSocket ¶
func WithWebSocket(enable bool) TransportOption
WithWebSocket makes the mqtt client use MQTT over WebSockets on port 443, which is great if e.g. port 8883 is blocked.
