Binary Protocol Overview

This is a custom binary protocol designed for communication between device and a server. It is used in scenarios like vehicle tracking, remote diagnostics, OTA (Over The Air) updates, and device configuration. Each packet is structured with a defined header, payload, and checksum for integrity. The payload structure varies based on packet type and purpose.

Advantages of Binary Protocol

Compact (saves bandwidth)
Faster to transmit and parse
Suitable for constrained environments like cellular networks (2G/4G)

Comparison with Text Protocol

No delimiters like commas, newlines, or JSON/XML formatting
Cannot be inspected or parsed in a terminal without a decoder

Packet Sending Modes

Packet sending modes are based on the device data update rate source selected. The update rate is speed-based.

The device can be in any of the following modes:

Motion Mode (M)

Based on the activity of Accelerometer.

Halt Mode (H)
