The fischertechnik TXT 4.0 Controller
​

Program like the pros!

The fischertechnik TXT 4.0 controller comes with lots of cool features! With its 512 MB RAM and 4 GB eMMC memory, three servo outputs and a capacitive touch display that supports swipe gestures, it offers lots of new features.
The improved WLAN and Bluetooth module offers the right wireless interface for numerous applications. Another interface is the USB host port, which can be used to connect the fischertechnik USB camera or USB sticks, for example. Up to eight additional controllers can be connected to one controller as extensions. Thanks to the flat housing, the controller can be perfectly integrated into the models. Firmware updates are automatically downloaded via the cloud so that you are always up to date, while your own programs are retained. The ROBO Pro Coding software can be used to program both graphically and with Python! ROBO Pro Coding is operating system-independent and can also be used on mobile devices. With an additional app (Android / iOS), the TXT 4.0 Controller can also be controlled via voice recognition.

But that's not all! Further features and information can be found on the product detail page.

      The software update of my TXT 4.0 controller stops at a progress of 99%.
      To resolve the problem, reinstall the same old software version that is already installed on the controller. Then restart the controller. You can now update to the latest software version. If this is also not possible, use a USB stick to update to the old firmware. This should be formatted with FAT32.
      The firmware file can be downloaded above.
      We have a TXT (not a TXT 4.0) controller and would like to program it with the new ROBO Pro Coding software. How should we proceed?

      The TXT Controller (predecessor of the TXT 4.0 Controller) cannot be programmed with the ROBO Pro Coding App because it is not supported in this app. Please use the ROBO Pro software under Windows for the TXT Controller.
      The ROBO Pro software can be downloaded via the button:

      How can the error be rectified that the TXT 4.0 controller cannot be connected to ROBO Pro Coding and "txtapi" is shown on the display of the TXT 4.0 controller.

      Please reinstall the TXT 4.0 controller firmware by following the instructions below:

      When updating firmware version 3.1.0 to version 3.1.x, the error message "Firmware installation failed!" is displayed. Even after restarting the controller, this error message appears repeatedly during the update, meaning that the firmware cannot be updated. How can the firmware 3.1.0 still be updated to the current firmware 3.1.x?
      In this case, the old firmware 3.1.0 must be updated again by selecting firmware 3.1.0 instead of the new firmware 3.1.x in the update dialog. Only when the error message "Firmware installation failed!" is no longer displayed after restarting the controller can an update to the latest firmware 3.1.x be carried out as described in the operating instructions. Important note: The power supply to the TXT 4.0 controller must not be interrupted during the update process.
      Shortly after switching on the TXT 4.0 controller, the ROBO Pro Coding app cannot be connected to the controller and instead of the green symbol, the yellow symbol is displayed in the top right-hand corner of ROBO Pro Coding.

      Check the IP address entered in the connection dialog to ensure that it is correct. Note: Connection to the TXT 4.0 Controller is only possible after a waiting time of approx. 30 seconds after switching on the TXT 4.0 Controller.

      Under which operating systems can "ROBO Pro Coding" be used?
      Windows, Mac, Linux, IOS and Android.
      Can the TXT 4.0 controller be programmed with the old "ROBO Pro" software?
      No, the TXT 4.0 controller is programmed using the new programming environment with the "ROBO Pro Coding" app.
      Where can I find the operating instructions for the TXT 4.0 Controller?
      See above.
      Updating the TXT 4.0 firmware version 3.1.0 to version 3.1.6 or newer is not possible via the Internet. How can the firmware 3.1.0 still be updated to the current firmware 3.1.x?
      In this case, the firmware 3.1.4 must be updated first and then the new firmware 3.1.x. Important note: The power supply to the TXT 4.0 controller must not be interrupted during the update process.
