"Firmware" is the type of software that is on your helmet and controller. Your Helmet has three types of firmware; CPU firmware, Bluetooth Firmware and Camera Firmware. The controller has one type. When Forcite releases new features or bug fixes, they occasionally require a firmware update to one or more systems to work.
To update your firmware, first connect your helmet or controller and go to Settings > Helmet > Firmware Update.
You will now be able to see the most up to date firmware available for your devices. If a firmware update is available, you will be presented with an "Update" button.
