Packet identification: 0xCAFE 2 bytes
+

Packet type: 01

UDP protocol is the same as TCP except message header is 7 bytes, which consist of: data length, packet identification, packet type and packet id.
+
+
Then goes imei length and imei itself.
+
+
And after that goes AVL data.
+
+
And at the very end number of data byte. There is no CRC in UDP.
