scapy.contrib.eddystone

scapy.contrib.eddystone - Google Eddystone Bluetooth LE proximity beacons.

The Eddystone specification can be found at: https://github.com/google/eddystone/blob/master/protocol-specification.md

These beacons are used as building blocks for other systems:

class scapy.contrib.eddystone.EddystoneURLField(name: str, default: Optional[scapy.fields.I], fmt: str = 'H', remain: int = 0)[source]

Bases: scapy.fields.StrField

any2i(pkt, x)[source]
i2m(pkt, x)[source]
m2i(pkt, x)[source]
class scapy.contrib.eddystone.Eddystone_EID(*args: Any, **kargs: Any)[source]

Bases: scapy.packet.Packet

An Eddystone type for transmitting encrypted, ephemeral identifiers.

This implementation does not support decrypting this data.
