Bases: SuperSocket

ISOTPSocket using the can-isotp kernel module

Parameters:

  • iface – a CANSocket instance or an interface name

  • tx_id – the CAN identifier of the sent CAN frames

  • rx_id – the CAN identifier of the received CAN frames

  • ext_address – the extended address of the sent ISOTP frames

  • rx_ext_address – the extended address of the received ISOTP frames

  • bs – block size sent in Flow Control ISOTP frames

  • stmin – minimum desired separation time sent in Flow Control ISOTP frames

  • padding – If True, pads sending packets with 0x00 which not count to the payload. Does not affect receiving packets.

  • listen_only – Does not send Flow Control frames if a First Frame is received

  • frame_txtime – Separation time between two CAN frames during send

  • basecls – base class of the packets emitted by this socket

recv(x: int = 65535, **kwargs: Any) → Packet | None[source]
recv_raw(x: int = 65535) → Tuple[Type[Packet] | None, bytes | None, float | None][source]

Receives a packet, then returns a tuple containing (cls, pkt_data, time)
