hi
i have  try it as follows, but it don't work :

guint8 address_bytes;
guint8 lon_unicast;

tvb_memcpy(tvb,(guint8 *)&lon_unicast, offset, 9);

proto_tree_add_bytes_format_value(lon_tree, hf_unicast, tvb,
offset,9,lon_unicast,"0x%s",bytes_to_str(address_bytes,9));


{hf_unicast,
{"unicast";
"lon.unicast",
FT_BYTES, BASE_HEX,NULL,0x0, "",HFILL}
},

thanks
