Types ¶
type Node ¶
type Node struct {
LongName string
ShortName string
ID uint32
HardwareModel pbuf.HardwareModel
}
func (*Node) EncryptPacket ¶
func (n *Node) EncryptPacket(pkt *pbuf.MeshPacket, channelName string, key []byte) *pbuf.MeshPacket
Not actually in use yet 😅
type NodeID ¶
type NodeID uint32
NodeID holds the node identifier. This is a uint32 value which uniquely identifies a node within a mesh.
func RandomNodeID ¶ added in v0.1.5
RandomNodeID returns a randomised NodeID. It's recommended to call this the first time a node is started and persist the result.
Hardware meshtastic nodes first try a NodeID of the last four bytes of the BLE MAC address. If that ID is already in use or invalid, a random NodeID is generated. Source: https://github.com/meshtastic/firmware/blob/d1ea58975755e146457a8345065e4ca357555275/src/mesh/NodeDB.cpp#L466
func (NodeID) DefaultLongName ¶ added in v0.1.5
DefaultLongName returns the default long node name based on the NodeID. Source: https://github.com/meshtastic/firmware/blob/d1ea58975755e146457a8345065e4ca357555275/src/mesh/NodeDB.cpp#L382
func (NodeID) DefaultShortName ¶ added in v0.1.5
DefaultShortName returns the default short node name based on the NodeID. Last two bytes of the NodeID represented in hex. Source: https://github.com/meshtastic/firmware/blob/d1ea58975755e146457a8345065e4ca357555275/src/mesh/NodeDB.cpp#L382
type PacketDeduplicator ¶ added in v0.1.5
type PacketDeduplicator struct {
sync.RWMutex // RWMutex is used to protect the seen map from concurrent access.
// contains filtered or unexported fields
}
PacketDeduplicator is a structure that prevents processing of duplicate packets. It keeps a record of seen packets and the time they were last seen.
func NewDeduplicator ¶ added in v0.1.5
func NewDeduplicator(hasher hash.Hash, expiresAfter time.Duration) *PacketDeduplicator
NewDeduplicator creates a new PacketDeduplicator with a given hasher and expiration duration for packet records. It starts a background goroutine to periodically clean up expired packet records.
func (*PacketDeduplicator) Seen ¶ added in v0.1.5
func (p *PacketDeduplicator) Seen(sender, packetID uint32) bool
Seen checks whether a packet with the given sender and packetID has been seen before. If not, it records the packet as seen and returns false. Otherwise, it returns true.
func (*PacketDeduplicator) SeenData ¶ added in v0.1.5
func (p *PacketDeduplicator) SeenData(data []byte) bool
SeenData checks whether the data has been seen before based on its hashed value. If not, it records the data as seen and returns false. Otherwise, it returns true.
