Hi , we are using proprietary protocol to carry the RRC messages between LTE Layer3 and Layer2 Also with help of wireshark generic dissector we get our protocol header and payload info, here payload is RRC messages which is printed in hex. so how to decode the payload (RRC messages) from or using generic dissector. pasted sample snippet

Frame 2806: 500 bytes on wire (4000 bits), 500 bytes captured (4000 bits)
Linux cooked capture v1
