SMSG_CHAR_ENUM returns error

[/dev/not/null]

I'm trying to send SMSG_CHAR_ENUM packet (example below):

1. Character data

data = pack(
            '<Q{name_len}s3B5BB2I3f2IB3IIBI'.format(name_len = len(name_bytes)),
            1,               # guid
            name_bytes,	     # 'Name' + '\x00'
            4,               # race
            11,              # class id
            0,               # gender
            0,               # skin
            0,               # face
            0,               # hair style
            0,               # hair color
            0,               # facial hair
            61,              # level
            141,             # zone id
            1,               # map id
            10322.1,         # x
            825.436,         # y
            1326.37,         # z
            0,               # guild
            0,               # char flags ?
            0,               # first login
            0,               # pet display id
            0,               # pet level
            0,               # pet family
            0,               # first bag inventory id
            0,               # first bag inventory type
            0                # enchant ?
        )

2. Full packet:

packet = pack('<B', num_chars) + data

But client returns 'Error retrieving character list'. What am I doing wrong ?

Hello,

Did you check big_endian & little_endian format ?

Some more info there: https://github.com/Warkdev/JaNGOSRealm/blob/master/src/main/java/eu/jangos/realm/network/packet/server/character/SMSG_CHAR_ENUM.java#L178

Yes, I did. Character data has little endian. When I sending empty SMSG_CHAR_ENUM (num_chars = 0 and no character data) all is OK. Something wrong with character data.

Edited response and added equipment data and first bag data to it. But no success(client still returns error):

name_bytes = name.encode('utf-8') + b'\x00'
        data = pack(
            '<Q{name_len}s3B5BB2I3f2IB3I'.format(name_len=len(name_bytes)),
            1,               # guid 0
            name_bytes,      # 1
            4,               # race 2
            11,              # class 3
            0,               # gender 4
            0,               # skin 5
            0,               # face 5
            0,               # hair style 5
            0,               # hair color 5

            0                # pet family 18
        )

        char_equipment = []

    	# 19 pieces of equipment
        for item in range(CharacterEquipSlot.HEAD.value, CharacterEquipSlot.TABARD.value + 1):
            char_equipment.append(pack('<IBI', 0, 0, 0))  # item display id - item inventory type - enchant

        # first bag data
        char_equipment.append(pack('<IBI', 0, 0, 0))  # first bag display id - inventory type - enchant

You probably need to compare a mangos trace with this to see where your fault is.

SMSG_CHAR_ENUM means an enumeration. The very first value you send (1 byte) is the number of characters (heroes) on the selected realm, not the number of characters in the name... After this field you start enumerating your characters, starting with their guid (8 bytes), name (null terminated), race, class, gender, skin, face etc. So, for example, if you have 5 heroes on the realm, you'll send 5 as the first byte and then 5 structures describing each of your hero, each one starting with the GUID. I cannot be more specific than this.

Cheers!
