Naubat communicates directly with the vehicle diagnostic system through a Bluetooth Low Energy OBD-II dongle. The communication model follows standard automotive diagnostic procedures used by professional diagnostic tools.Diagram placeholder: Smartphone to BLE dongle to OBD port to vehicle ECUs.
Modern vehicles include multiple Electronic Control Units, also known as ECUs.
These ECUs exchange information through internal vehicle networks.
Automotive diagnostic standards provide structured read access to vehicle parameters.
Naubat uses standardized diagnostic services, including UDS, Unified Diagnostic Services.
This class of communication is used in professional workshops and during vehicle servicing.Naubat performs read-only diagnostic requests.
No vehicle parameters are modified.
No coding, flashing, or configuration changes are performed.This read-only model is non-intrusive and designed for safe operation.
The OBD-II port provides standardized physical access to vehicle diagnostics.
A Bluetooth dongle acts as the communication bridge between smartphone and vehicle.
Most consumer dongles are based on ELM327-compatible chipsets.
ELM327 is a widely adopted diagnostic interpreter chip used across many tools.There are multiple firmware versions and quality levels.
Connection stability and firmware quality affect communication reliability.
Naubat requires BLE dongles for stable background operation.
The app detects the dongle automatically when it is in range.
When the vehicle becomes active, structured diagnostic requests are initiated.
Data collection continues while the vehicle is operating.
When the vehicle returns to idle state, communication activity pauses.
Most commercial dongles consume only tens of milliamps during operation.
Many modern dongles include auto-sleep or low-power modes.
When no vehicle or Bluetooth activity is detected, these dongles typically enter reduced-power state.
Naubat communicates only when necessary for diagnostic collection.The system is designed not to cause significant 12V battery drain in normal use.
For extended inactivity periods of several days or more, unplugging the dongle is recommended as a precaution.
