Capture a Cityeasy fingerprint
Confirm a binary frame that opens SS with a 7-byte IMEI and type 0x0003 or 0x0004, not an EasyTrack star line.
-
2
Point Cityeasy at 5088
Configure only Cityeasy to TCP 5088. Cityeasy on 5088 is not EasyTrack on 5056 or GT02 on 5022.
-
3
Do not wait for an ACK
A Cityeasy location report has no reply byte. A parsed A-status body is enough.
-
4
Prove one Cityeasy fix
Send one 0x0003 body whose status is A on 5088 and verify a map point.

Cityeasy still not landing
- Cityeasy aimed at the wrong port
Cityeasy on 5088 is not EasyTrack on 5056 or GT02 on 5022.
- Session up, empty map
Type must be 0x0003 or 0x0004 and status must be A. A V status binds the IMEI and will not plot.
- Cell-only body, no first fix
A body that starts at the semicolon reuses the last point. Send one A-status GPS group first.
