Note that there is a five seconds timeout interval during which the Go to Cloud (G2C) click operates in a firmware update
mode as explained in the Boot-up sequence section of this manual. After this, the Go to Cloud (G2C) click is restarted and
will continue running in a normal mode, completely skipping the bootloader, and will be undetectable for the HID bootloader
application. If this happens, it is necessary to disconnect the USB cable and connect it again, initiating another five seconds
interval.
After the MCU of the Go to Cloud (G2C) click is detected as on the picture above, an appropriate HEX file with a proper
firmware version should be selected by clicking on the Browse for HEX button. This will open a file selection window, where
you can browse for the updated firmware file with the .hex extension. Once selected, the programming process can be
started by clicking the Begin uploading button. The programming process should take up to 60 seconds. If it takes longer, or
the process is interrupted during the update, it should be repeated from the beginning.
