	~~Packet sending modes are based on~~ the ~~device~~ data ~~update rate source selected~~. ~~The update rate is speed-based~~.		The vehicle’s mode is determined using a combination of location data from the GPS module, accelerometer data from the LIS2DE12 sensor, and the ignition state. These inputs are used to classify the vehicle's current mode into one of the following: Motion Mode, Halt Mode, or Sleep Mode.

	=== Motion Mode (M) ===		=== Motion Mode (M) ===
	~~Based on~~ the ~~activity~~ of ~~Accelerometer~~.		Motion Mode is activated when either of the following conditions is met:
			* Linear Acceleration: The linear acceleration exceeds 0.5 m/s².
			* Speed: The vehicle’s speed exceeds the threshold of 10 km/h.
			Only one of these conditions needs to be satisfied for the system to enter Motion Mode. This indicates that the vehicle is in motion.

	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.
