1
Capture a Dolphin fingerprint
Confirm a little-endian binary head, a 64-bit unit id, and a protobuf DataPack_Request body. Reject Ennfu: ASCII.
-
2
Point Dolphin at 5219
Configure only Dolphin to TCP 5219. Dolphin on 5219 is not Ennfu on 5220 or MAX PB on 5221.

3
Wait for 0xABAB DataPack_OK
Traxelio answers 0xABAB, the same index, DataPack_Response, and DataPack_OK. That reply is not a map point.

4
Prove one Dolphin fix
Send one DataPack_Request whose points list includes latitude and longitude on 5219 and verify a map point.

Dolphin still not landing
- Dolphin aimed at the wrong port
Dolphin on 5219 is not Ennfu ASCII on 5220, MAX PB type 0x0001 on 5221, or DMT 0x02 0x55 on 5137.
- Saw 0xABAB, empty map
The 0xABAB DataPack_OK reply only confirms the pack. A map point needs at least one DataPack point with lat/lon.
- Ennfu: line on 5219
Ennfu ASCII belongs on 5220. Dolphin is a protobuf DataPack after a little-endian binary head.
FAQ
Dolphin leftover questions
Does Dolphin send Concox 0x7878 frames?
No. Dolphin wraps a protobuf DataPack_Request after a little-endian binary head. Concox families use 0x7878 binary login.
What reply does a Dolphin unit get?
Header 0xABAB, the same index, a DataPack_Response type, and DataPack_OK. That reply is not a map point.
How many map points can one Dolphin pack carry?
One DataPack_Request can carry several points. Each point has latitude, longitude, altitude, speed, and bearing.
How does a Dolphin unit present its id?
A 64-bit little-endian number in the binary head, before the protobuf body.
Can a Dolphin unit run SMS setup or a controlled-action flow?
This dialect is positions only. One catalogue unit is listed: DO107. There is no SMS family on this row.
