Teltonika Codec 8 / Codec 8 Extended TCP Server and Parser

Personal Hobby project with Python.

Simple TCP server which listens for Teltonika trackers communicating via Codec 8 Extended using TCP

Server waits for device to send IMEI then responds with "01", device then must send Codec 8 Extended packet, server responds with records number.

Codec 8 documentation can found via URL bellow: https://wiki.teltonika-gps.com/view/Codec

Server - Device communication must work but not yet tested - works

AVL IDs are parsed, AVL Data - not yet parsed - partially parsed

AVL IDs and Raw values ar saved in ./data/data.json

Project Features:

• TCP communaction - done!
• Codec 8 Extended structure parsing - done!
• Codec 8 structure parsing - done!
• Saving AVL IDs with RAW/Parsed values to JSON - done!
• TCP Server and Parser functionality - done!
• CRC16 checking to detect corupted packets - done!
• RAW DATA saving to separate .JSON - done!
• Seprate .JSON files for different IMEIs - done!

Planed Features - not done yet:

• Codec 8 (not extended support) - not done yet - done!
• AVL IDs value parsing - not done yet - progress ongoing
• Make server multithreaded (code rewrite may be required) - not done yet
• Seprate .JSON files for different IMEIs - not done yet - done!
• More... - not done yet

How to test?:

• Install latest Python version from: https://www.python.org/
• Download "main.py" and Data folder: ./data/data.json - now created automatically
• Open "main.py" with any text editor, change 'port' to YOUR open Port
• Run "main.py" via terminal
• Follow on screen instructions
