xbee transport

A xbee API mode transport for bifrost.

This is an implementation of a bifrost transport that uses xbee radios.

  • Xbees are controlled with the gobee library in API mode.
  • Incoming packets are matched to a connection by transmitter ID
  • Incoming packet without a matching connection triggers an Accept() return
  • If configured, nodes may emit discovery pings, which contain a signed message with peer ID, timestamp, public key, device MAC.
  • Not hearing from a peer for a connection timeout length leads to a connection close event.

Note: discovery is not yet implemented in Bifrost.

Xbee Setup

Reset the xbees to default values, then set:

  • AP: 2 (API mode with escapes)
  • Baud: 115200

This will be automatic eventually.

E2E Test

Testing basic communications between two xbees connected via USB or another serial port is easily done with xbe2e. The tool accepts CLI arguments to set the baudrates and serial ports. It opens + configures both xbee using the xbserial common code, reads the local addresses, and transmits some data between them (unencrypted) as a basic test.

Types

type Config 

type Config struct {

	// TransportPeerID sets the peer ID to attach the transport to.
	// If unset, attaches to any running peer with a private key.
	TransportPeerId string `protobuf:"bytes,1,opt,name=transport_peer_id,json=transportPeerId,proto3" json:"transport_peer_id,omitempty"`
	// DevicePath is the device path to open the serial stream.
	DevicePath string `protobuf:"bytes,2,opt,name=device_path,json=devicePath,proto3" json:"device_path,omitempty"`
	// DeviceBaud is the device baudrate.
	DeviceBaud int32 `protobuf:"varint,3,opt,name=device_baud,json=deviceBaud,proto3" json:"device_baud,omitempty"`
	// PacketOpts are options to set on the packet connection.
	// In lossy environments, set the data shards for error correction.
	PacketOpts *kcp.Opts `protobuf:"bytes,4,opt,name=packet_opts,json=packetOpts,proto3" json:"packet_opts,omitempty"`
	// Dialers maps peer IDs to dialers.
	Dialers map[string]*dialer.DialerOpts `` /* 155-byte string literal not displayed */
	// contains filtered or unexported fields
}

Config is the configuration for the udp transport.

func (*Config) Descriptor deprecated 

func (*Config) Descriptor() ([]byte, []int)

Deprecated: Use Config.ProtoReflect.Descriptor instead.

func (*Config) EqualVT added in v0.3.0 

func (this *Config) EqualVT(that *Config) bool

func (*Config) EqualsConfig 

func (c *Config) EqualsConfig(other config.Config) bool

EqualsConfig checks if the other config is equal.

func (*Config) GetConfigID 

func (c *Config) GetConfigID() string

GetConfigID returns the unique string for this configuration type. This string is stored with the encoded config. Example: bifrost/transport/xbee/1

func (*Config) GetDebugVals 

func (c *Config) GetDebugVals() config.DebugValues

GetDebugVals returns the directive arguments as key/value pairs. This should be something like param1="test", param2="test". This is not necessarily unique, and is primarily intended for display.

func (*Config) GetDeviceBaud 

func (x *Config) GetDeviceBaud() int32

func (*Config) GetDevicePath 

func (x *Config) GetDevicePath() string

func (*Config) GetDialers 

func (x *Config) GetDialers() map[string]*dialer.DialerOpts

func (*Config) GetPacketOpts 

func (x *Config) GetPacketOpts() *kcp.Opts

func (*Config) GetTransportPeerId 

func (x *Config) GetTransportPeerId() string

func (*Config) MarshalToSizedBufferVT added in v0.2.0 

func (m *Config) MarshalToSizedBufferVT(dAtA []byte) (int, error)

func (*Config) MarshalToVT added in v0.2.0 

func (m *Config) MarshalToVT(dAtA []byte) (int, error)

func (*Config) MarshalVT added in v0.2.0 

func (m *Config) MarshalVT() (dAtA []byte, err error)

func (*Config) ParseNodePeerID 

func (c *Config) ParseNodePeerID() (peer.ID, error)

ParseNodePeerID parses the node peer ID if it is not empty.

func (*Config) ProtoMessage 

func (*Config) ProtoMessage()

func (*Config) ProtoReflect added in v0.2.0 

func (x *Config) ProtoReflect() protoreflect.Message

func (*Config) Reset 

func (x *Config) Reset()

func (*Config) SetTransportPeerId 

func (c *Config) SetTransportPeerId(peerID string)

SetTransportPeerId sets the node peer ID field.

func (*Config) SizeVT added in v0.2.0 

func (m *Config) SizeVT() (n int)

func (*Config) String 

func (x *Config) String() string

func (*Config) UnmarshalVT added in v0.2.0 

func (m *Config) UnmarshalVT(dAtA []byte) error

func (*Config) Validate 

func (c *Config) Validate() error

Validate validates the configuration. This is a cursory validation to see if the values "look correct."

type Factory 

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

Factory constructs a XBee transport.

func NewFactory 

func NewFactory(bus bus.Bus) *Factory

NewFactory builds a XBee transport factory.

func (*Factory) Construct 

func (t *Factory) Construct(
	conf config.Config,
	opts controller.ConstructOpts,
) (controller.Controller, error)

Construct constructs the associated controller given configuration. The transport's identity (private key) comes from a GetNode lookup.

func (*Factory) ConstructConfig 

func (t *Factory) ConstructConfig() config.Config

ConstructConfig constructs an instance of the controller configuration.

func (*Factory) GetConfigID 

func (t *Factory) GetConfigID() string

GetConfigID returns the configuration ID for the controller.

func (*Factory) GetControllerID 

func (t *Factory) GetControllerID() string

func (*Factory) GetVersion 

func (t *Factory) GetVersion() semver.Version

GetVersion returns the version of this controller. 

type Link = pconn.Link

Link represents a xbee-based connection/link.

	*pconn.Transport
	// contains filtered or unexported fields
}
