Do not use any other .hex files not designed for Thymio II!
This could permanently damage your robot.**

What is a firmware?

The firmware is the software inside your Thymio. It provides the pre-programmed behaviours and allows you to program the robot. It is not the software you write for Thymio. Just as with the software on your computer or your smartphone, you can upgrade the firmware so as to add new features or to correct bugs.

My code isn't working anymore

Depending on the version of the firmware that was previously in your robot, updating the firmware might change the name of some variables and functions, therefore you may have to adapt your code, please refer to the programming interface page for more details.
