XR25 BLE — FENIX LAB

Original diagnostics, current interface.

Renault ECUs using the XR25 protocol already expose a large amount of internal information. XR25 BLE modernizes access to that data without replacing the ECU or changing the original protocol.

The module connects to the vehicle, communicates with the ECU and sends the data to an Android application over Bluetooth Low Energy.

No PCThe phone becomes the interface

No suitcaseNo period XR25 equipment required

No cableNo wired link to the phone

Real-time engine data

The application interprets XR25 data and presents it in an interface designed for in-car use. Available values depend on the ECU and its program.

Engine speed, temperatures, pressure, vehicle speed and internal states can be displayed whenever the ECU profile exposes them.

An interface you can organize

Useful information can be arranged to match the task: numerical values, gauges, status indicators and graphs. The aim is to let each user build a display suited to diagnostics, tuning or simple monitoring while driving.

Screenshots

XR25 BLE Android app

These screenshots come from the Android app paired with the XR25 BLE module. They show XR25 frame reception, recording, dashboard views and flag reading.

The interface is designed to use XR25 diagnostics directly on a smartphone, without a PC or vintage diagnostic unit.

Documented XR25 ECUs and vehicles

Documented XR25 profiles include Renault 21 2L Turbo, Clio 16S, Clio Williams, Renault 25 V6 Turbo and Safrane V6 Biturbo, with the ECU program references listed by FENIX LAB.

Compatibility
Undocumented references are not advertised as compatible until their XR25 protocol has been verified.

Designed for EvoPROM too

With Fenix 1B EvoPROM, the same interface can also display additional information exposed through the enriched XR25 frame.
