Introduction

Meet the xA Ultra — the only adapter you’ll ever need.

Developed entirely in-house, the xA Ultra is a KLINE/DCAN/ENET Wi-Fi adapter that supports all BMW E-, F-, and G-Series models (2003–present).

It features an LED status indicator for flash progress and an exclusive energy-saving mode, so it can stay plugged into the OBD port forever without draining your battery.

Setting up the xA Ultra

1. Update your App

Make sure you’re using the latest version of either xProtect/xHP Flashtool or xDelete.

2. Plug In the Adapter

When you plug in the xA Ultra for the first time, no LED will light up — that’s normal.
A firmware update is required before first use.

3. Update the Adapter Firmware

The xHP will recognise the xA Ultra adapter automatically and download the latest firmware.

  • Open your device’s Wi-Fi settings and connect to the network named
    xAU_FACTORY_XXXXXX created by the adapter.
    (It may take some time before the Wi-Fi appears.)

  • In your App, either:

    • Tap “CONNECT NEW CAR” to start the guided update, or

    • Tap the “xA Ultra” button (top-left corner) to open the firmware page.

  • Wait until the update finishes.

  • Reconnect to the new Wi-Fi name: xA_Ultra_XXXXXX.

4. LED Indicator Colours After Update

Your adapter is now ready for use with xHP, xDelete, MHD, Bootmod3, etc.

xA Ultra Technical Information for Developers

The xA Ultra supports E, F and G-Series protocols (KWP and UDS) and features automatic CAN and ENET detection.

When the adapter detects ENET, it lights up blue; if ENET is not present, it falls back to CAN mode and lights up orange.

In ENET mode, both ENET and CAN are available simultaneously and can be accessed via separate ports.

ENET mode 🔵 Blue:
IP: Transparent/DHCP
ControlPort: 6811
DiagnosticPort: 6801

CAN Mode 🟠 Orange:
IP: 192.168.4.1
Port: 23

An HTTP configuration page is available at http://192.168.4.1:58424/config, where the following items can be modified:

  • Change the SSID

  • Set a Wi-Fi password

  • LED behaviour (Standard, Minimal or Off)

  • Power mode (always on, ignition or CAN active, ignition only).

OTA firmware upgrades are only possible through xAutomotive apps. The first time you use it, you must upgrade the factory firmware using one of our apps.
