UDS Whisperer by efs

Do you want to avoid implementing time-critical and complex UDS sequences directly in your mobile app?
Should the dongle autonomously read data from ECUs periodically or when certain events occur?

UDS Whisperer handles reliable timing, protocol control, and data acquisition directly in the vehicle — periodically or event-driven, all without requiring any additional code in your app. This keeps your application lean, stable, and focused on what truly matters: intuitive operation and real value for the user.

Do you want to record measurement values or diagnostic data regularly without your app needing to run continuously?

UDS Whisperer cyclically records relevant DIDs or PIDs, stores them locally, and reacts to defined events or triggers. This allows states, anomalies, or special driving moments to be documented automatically — like a data recorder for vehicle diagnostics.

Saved log data can be conveniently exported via WiFi and processed centrally.
This provides you with a reliable data foundation for analysis, validation, or fleet monitoring — independent of the app, location, or connection.

Do you want to document vehicle identifications or software versions automatically — without a laptop or manual interaction? When plugged into the vehicle, UDS Whisperer independently reads the VIN and relevant version information and transfers them to a nearby base station or directly to the backend.

This allows vehicle movements, software updates, or commissioning processes to be recorded automatically and reliably — efficient, error-free, and fully integrated into your infrastructure.

Do you want to efficiently supply large numbers of vehicles with new software versions or datasets — without a laptop or complex operation?
UDS Whisperer receives the OTA package in advance via the cloud and automatically performs the flashing process immediately after being plugged in.

Progress is indicated through multi-color status LEDs, and after successful completion, the dongle sends the VIN and software version back to the backend.
This makes the update and commissioning process simple, safe, and repeatable — ideal for workshops, test fleets, and series processes.

Whether at a customer site in Shanghai, during winter testing in Arctic conditions, or on the proving ground:
UDS Whisperer securely connects the vehicle with the workshop or development team — anywhere in the world.

Via cloud, Wi-Fi access point, or mobile hotspot, a diagnostic tool can access the vehicle remotely, read faults, communicate with ECUs, or collect data — just as if it were physically in the workshop.
This enables seamless global diagnostics, support, and analysis — fast, secure, and independent of location.

UDS Whisperer enables the capture, storage, and forwarding of vehicle data — entirely without a connected PC.
Measurement, diagnostic, and communication data are processed directly within the device and, when needed, transferred to existing systems via WiFi or USB.

Thanks to open interfaces and standardized protocols, the dongle can be seamlessly integrated into HIL environments, test systems, and tool chains.
This creates a compact, autonomous solution for logging, monitoring, and automated test workflows.
