digi.xbee.packets.relay.
UserDataRelayPacket
(frame_id, local_interface, data=None)[source]¶ Bases:
digi.xbee.packets.base.XBeeAPIPacket
This class represents a User Data Relay packet. Packet is built using the parameters of the constructor.
The User Data Relay packet allows for data to come in on an interface with a designation of the target interface for the data to be output on.
The destination interface must be one of the interfaces found in the corresponding enumerator (see
XBeeLocalInterface
).Class constructor. Instantiates a new
UserDataRelayPacket
object with the provided parameters.Parameters: - frame_id (integer) – the frame ID of the packet.
- local_interface (
XBeeLocalInterface
) – the destination interface. - data (Bytearray, optional) – Data to send to the destination interface.

Raises: - ValueError – if
local_interface
isNone
. - ValueError – if
frame_id
is less than 0 or greater than 255.

static
create_packet
(raw, operating_mode)[source]¶ Override method.
Returns: Raises: - InvalidPacketException – if the bytearray length is less than 7. (start delim. + length (2 bytes) + frame type + frame id + relay interface + checksum = 7 bytes).
- InvalidPacketException – if the length field of ‘raw’ is different than its real length. (length field: bytes 2 and 3)
- InvalidPacketException – if the first byte of ‘raw’ is not the header byte. See
SpecialByte
. - InvalidPacketException – if the calculated checksum is different than the checksum field value (last byte).
- InvalidPacketException – if the frame type is not
ApiFrameType.USER_DATA_RELAY_REQUEST
. - InvalidOperatingModeException – if
operating_mode
is not supported.
