Advanced Configuration

Some advanced configuration settings are available for expert users tune-up. This should be modified only if you are comfortable changing XML files and understanding XML syntax.

The advanced configuration parameters are stored in file RFETouch.xml. This file can be found in following locations depending on OS:

  • Windows platforms: %APPDATA%\RFExplorer
  • MacOS platforms: /User/<Username>/.RFE
  • Linux platforms: <Home>/.RFE

Only these parameters below should be modified, other RFETouch.xml configuration parameters should not be modified. Note incorrect file update may damage XML structure or values and may lead to configuration loss. It is advisable to backup the RFETouch.xml before any modification is made.








Use true for IoT module, or false for Handheld Analyzer. This setting is set by default to true in Raspberry Pi SDCard image files, and false otherwise




Use true to shutdown Linux when RFETouch is closed, other case set to false. This setting is set by default to true in Raspberry Pi SDCard image files, and false otherwise




For Raspberry Pi only: Set serial port name either as /dev/ttyAMA0 or /dev/ttyS0 depending on UART configuration (useful in Raspberry Pi 4B). This parameter is ignored for USB devices, only RF Explorer IoT module is affected by this setting in a Raspberry Pi.

Raspberry Pi: How to disable RFETouch auto-start:

In SDCard images provided for Raspberry Pi, the RFETouch application is configured to automatically start after the Raspbian GUI is loaded. If you want to disable this behavior and load RFETouch manually, locate the autostart configuration file which may be in one of the following locations, depending on Raspberry Pi model:

  • /home/pi/.config/lxsession/LXDE-pi/autostart
  • /etc/xdg/lxsession/LXDE-pi/autostart

Edit this file using <sudo nano> or equivalent editor as superuser, and remove this line:

  • @lxterminal -e sudo /home/pi/RFExplorer/RFETouch
