To get the mac-nr decoded buffer, the context part was filled and data was sent over udp port.Wanted to decode the sf-sfn in the context part , so sent the data as below over udp
Medium access control (MAC) layer protocol data unit (PDU) becomes physical layer service data unit (SDU). In telecommunications, a protocol data unit (PDU) is a single unit of information transmitted among peer entities of a computer network. A PDU is composed of protocol specific control information and user data. Medium Access Control (MAC) for LTE. This protocol is layer 2 of the LTE air interface (connecting an LTE UE with an eNodeB). Protocol dependencies. MAC-LTE runs over the PHY layer; A UDP framing format for MAC-LTE has been defined (described in packet-mac-lte.h, purely for use with Wireshark).
UDP data -
Decoded fields
UDP data is filled as below
The wireshark version used here to decode is 3.00, i see only till ueid the context gets decoded and the payload as wellThe subframe header tag seems to be fine as per the findings. Could any one help as to why it is not getting decoded or anything missing from my end .???

A protocol data unit is information delivered as a unit among peer entities of networks containing control information, address information or data. In layered systems, PDU represents a unit of data specified in the protocol of a given layer, which consists of protocol control information and user data.PDU is a significant term related to the initial four layers of the OSI model.
In Layer 1, PDU is a bit, in Layer 2 it is a frame, in Layer 3 it is a packet and in Layer 4 it is a segment. In Layer 5 and above, PDU is referred to as data.PDU has four fields: the destination service access point, source service access point, control field and information field. In packet-switched data networks, PDU is related to a service data unit.
