-
1
Capture an MTA 6 fingerprint
Confirm HTTP id= then &bin= with a packed binary body. Reject #MTX, captures as the wrong neighbor.
-
2
Point MTA 6 at 5028
Configure only MTA 6 to HTTP 5028. MTA 6 on 5028 is not MTX on 5083 or OsmAnd on 5055.
-
3
Wait for the #ACK# reply
A known unit gets HTTP 100 then HTTP 200 whose body starts with #ACK# plus packet id, packet count, and a 0.
-
4
Prove one MTA 6 fix
Send one 0x31, 0x32, or 0x36 packet with satellites 3 or more on 5028 and verify a map point.
Still offline after GPS lock
MTA6 still not landing
- MTA 6 aimed at the wrong port
MTA 6 on 5028 is not MTX on 5083 or OsmAnd on 5055.
- HTTP 200, empty map
Need packet 0x31, 0x32, or 0x36 and a satellite count of 3 or more. #ACK# alone is not a plot.
- Waiting for an ASCII CSV line
MTA 6 is HTTP plus packed binary after &bin=. A #MTX, line belongs on 5083.
FAQ
MTA6 leftover questions
Does MTA 6 send Concox 0x7878 frames?
No. MTA 6 posts id= then &bin= with packed IEEE floats. Concox families use 0x7878 binary login.
What does an MTA 6 ACK look like?
HTTP 200 whose body starts with #ACK# plus the packet id, the packet count, and a trailing 0.
Why does an MTA 6 body bind without a map fix?
The binary must carry packet 0x31, 0x32, or 0x36, and the satellite count must be 3 or more.
How are MTA 6 coordinates packed?
Compressed IEEE floats in radians, then converted to degrees. Time is GPS week from 1980-01-06.
Can an MTA 6 unit run SMS setup or a controlled-action flow?
This dialect is positions only. Gruz, MPU-01, and MTA-02 class units are listed. There is no SMS family on this row.
