fluffykaon / tomtom-ttbin-file-format Goto Github PK

Hello,
I never used github, excuse me if I do something wrong.
Also my English isn't good.

I have got a tomtom multisports and I am very interested in your work.

I connect my tomtom to a windows PC, I copy the .ttbin file to a linux PC and use your program to decript it, but don't works fine, your program reads the ttbin, but generate many files.

Can I compile your program in windows ? How ?

Thank you very much,

Antonio de la Vega

Hi,

First of all congratulate you for your work.

i am a programmer and like investigate ttbin file format too.

I have one tomtom multisport watch with version 1.8.25 firmware.

I have discovered what information has the tag 0x3Fh (63 decimal).

In my workouts is always the third TAG beginning from the bottom of the file.

TAG Length: 9
TAG Example1: 3F 04 00 00 00 2E 00 00 00
TAG Example2: 3F 03 00 00 00 24 00 00 00
TAG Example3: 3F 04 00 00 00 30 00 00 00
TAG Example4: 3F 04 00 00 00 30 00 00 00

Info:

First Byte 3F - TAG Code
Second byte: 0x04h Excelent, 0x03h Good, other values i don't have examples
Third, Fourth and fifth byte always 0
Sixth Byte: Heart Rate Recovery (46, 36, 48, 48 decimal values obtained from watch)
seventh, eighth and ninth always 0

I can send you ttbin files with this information if you need it.

Regards

Jorge

The u1 field in the GPS information structure (0x22) is actually the Heading, in degrees * 100.

[edit] 0 is due north, incrementing in a clockwise direction, so 9000 is due east, 18000 is due south, 27000 is due west.
