Setting Up Your XM125/XE125

The XE125 is an evaluation board which has the XM125 module soldered onto it. All you need to connect it to a PC is a USB-C cable (not provided by Acconeer).

Hardware Overview

The image below depicts the XE125 from the front (left) and back (right).

Finding the Serial Port

In preparation for connecting and flashing, it is good to know the serial port of the device.

Windows Linux

Use Device Manager to find the port. It is listed under Ports (COM & LPT) as USB Serial Port or Enhanced COM Port. It’s most likely COMx where x is 3 or higher.

PySerial has a simple tool for listing all ports available:

python -m serial.tools.list_ports

Note that when the XE125 is connected to a PC, two virtual serial ports will appear:

• Enhanced

• Standard

Use the enhanced port (usually the first one) when connecting to the module from the Exploration Tool application.

Windows COM Port Drivers

If no COM port is recognized when plugging in a module, you need to install a driver:

• XM125: Silicon Labs

Flashing

The most convenient method to prepare the XM125 board for flashing is to let the Exploration Tool Application automatically download the latest binary file from our developer page. If you want to flash a binary that you have locally on your computer; that is also possible.

Depending on how you installed in Exploration Tool Installation, start Exploration Tool by either

• Double-clicking the run_app script,

• Running the command python -m acconeer.exptool.app in your terminal.

Then get started by pressing the Flash button in Exploration Tool and you will be guided through the flashing process.
