GoSafe Protocol (*GS / *GS02 text + binary)

1
Capture a GoSafe fingerprint
Confirm *GS text closed by # with a GPS: fragment, or a binary record that ends 0xF8.

2
Point GoSafe at 5078
Configure only GoSafe to TCP or UDP 5078. GoSafe on 5078 is not GlobalSat on 5043 or FutureWay on 5213.
-
3
Treat 1234 as a reply, not a fix
Traxelio answers ASCII 1234 on a parsed record. Check the map for GPS:A or binary lat/lon.
-
4
Prove one GoSafe fix
Send one GPS:A fragment, or a binary GPS block whose lat/lon parse, then verify a map point.
Still offline after GPS lock
Gosafe still not landing
- GoSafe aimed at the wrong neighbor
GoSafe on 5078 is not GlobalSat GSr on 5043 or FutureWay hex GPS: on 5213.
- 1234 reply, empty map
ASCII 1234 is only a parse reply. Status must be A, or the binary GPS mask must carry lat/lon.
- GSr text, assumed GoSafe
This dialect needs a leading *GS and a trailing #. GSr CSV belongs on 5043.
FAQ
Gosafe leftover questions
Does GoSafe send Concox 0x7878 frames?
No. GoSafe is *GS text closed by # or binary closed by 0xF8. Concox families use 0x7878 binary login.
Which GPS letter plots a GoSafe fix?
A plots. V is void and will not plot a new point.
Does GoSafe send an ACK?
Traxelio answers ASCII 1234. That 1234 is not proof a map point landed.
What sits after *GS on a modern line?
A version, then the IMEI, then fragments such as GPS: A;sats;Nlat;Elon. Several records can split on $.
Can a GoSafe unit run SMS setup or a controlled-action flow?
This dialect is positions only. There is no SMS family on this row.
