I'm trying to receive simple udp packet with length and data.
Packet structure has no header/trailer and like followings.
|LENGTH(2byte)|DATA(variable length)|
ex)
0C 00 00 01 02 03 04 05 06 07 08 09 0a 0b

I defined in the protocol like followings but didn't work.
The packets can be seen in stream viewer but not handled in the connector.

<Param id="100">
<Name>DataLength</Name>
<Type>length</Type>
<Interprete>
<RawType>numeric text</RawType>
<LengthType>fixed</LengthType>
<Length>2</Length>
<Type>double</Type>
</Interprete>
<Length>
<Content>
<Param>1</Param>
</Content>
</Length>
</Param>

<Param id="101">
<Name>DataBody</Name>
<Type>read</Type>
<Interprete>
<RawType>other</RawType>
<Type>string</Type>
<LengthType>next param</LengthType>
</Interprete>
</Param>

<Response id="100">

<Param>100</Param>
<Param>101</Param>

<Time>before</Time>
<Type>action</Type>
<Content>
<Id>10</Id>
<Id>11</Id>

</Trigger>

<Trigger id="101">

<On id="100">response</On>
<Time>after</Time>
<Type>action</Type>
<Content>
<Id>100</Id>

</Trigger>

<Action id="10">

<On>response</On>
<Type>read</Type>
</Action>
<Action id="11">
<Name>Response Length</Name>
<On>response</On>
<Type>length</Type>
</Action>

Something wrong or missing?
