Something seems to be very off in the way the data is packed up

[sosukeinu]

I feel like I may be missing something here. I'm springboarding off the example sender like:

    pdu = EntityStatePdu()
    pdu.length = 144 #gotta figure this shit out
    pdu.exerciseID = 250
    pdu.entityID.entityID = 42
    pdu.entityID.siteID = 1
    pdu.entityID.applicationID = 11
    pdu.marking.setString('Igor3d')
    pdu.entityType.domain = 2
    pdu.entityType.country = 255
    pdu.entityType.entityKind = 1

    pdu.forceId = 1

    myLocation = [-5.482955764588357,   # longitude
                    35.198894404096315, # latitude
                    10000,               # altitude
                    0,               # roll
                    0,               # pitch
                    0                # yaw
                     ]
    pdu.entityLocation.x = myLocation[0]
    pdu.entityLocation.y = myLocation[1]
    pdu.entityLocation.z = myLocation[2]
    pdu.entityOrientation.psi = myLocation[3]
    pdu.entityOrientation.theta = myLocation[4]
    pdu.entityOrientation.phi = myLocation[5]
    
    memoryStream = BytesIO()
    outputStream = DataOutputStream(memoryStream)
    pdu.serialize(outputStream)
    data = memoryStream.getvalue()

    while True:
        udpSocket.sendto(data, (DESTINATION_ADDRESS, UDP_PORT))
        pp.pprint(vars(pdu))
        pp.pprint(vars(pdu.entityID))
        pp.pprint(vars(pdu.entityType))
        pp.pprint(vars(pdu.entityLocation))
        print("Sent {}. {} bytes to {}:{}".format(pdu.__class__.__name__, len(data), DESTINATION_ADDRESS, UDP_PORT))
        time.sleep(5)

Then, when I send the data it is printed as below:

{   'alternativeEntityType': <opendis.dis7.EntityType object at 0x7f0a18fb81c0>,
    'capabilities': 0,
    'deadReckoningParameters': <opendis.dis7.DeadReckoningParameters object at 0x7f0a18fb8bb0>,
    'entityAppearance': 0,
    'entityID': <opendis.dis7.EntityID object at 0x7f0a18fb83d0>,
    'entityLinearVelocity': <opendis.dis7.Vector3Float object at 0x7f0a18fb85e0>,
    'entityLocation': <opendis.dis7.Vector3Double object at 0x7f0a18fb86a0>,

    'entityType': <opendis.dis7.EntityType object at 0x7f0a18fb8cd0>,
    'exerciseID': 250,
    'forceId': 1,
    'length': 144,
    'marking': <opendis.dis7.EntityMarking object at 0x7f0a1869f4c0>,
    'numberOfVariableParameters': 0,
    'padding': 0,
    'pduStatus': 0,
    'pduType': 1,
    'protocolFamily': 1,
    'protocolVersion': 7,
    'timestamp': 0,
    'variableParameters': []}
{'applicationID': 11, 'entityID': 42, 'siteID': 1}
{   'category': 0,
    'country': 255,
    'domain': 2,
    'entityKind': 1,
    'extra': 0,
    'specific': 0,
    'subcategory': 0}
{'x': -5.482955764588357, 'y': 35.198894404096315, 'z': 10000}

Looks great so far. HOWEVER, when I check the packet in Wireshark I get:

As you can see, the entityType and location info is ignored or changed. Any help in understanding what I'm doing wrong would be greatly appreciated. Thank you
