mode. If there is no response from the USB HID Bootloader application while the Go to Cloud (G2C) click is in the
bootloader mode, the normal operation of the Go to Cloud (G2C) click will be resumed and the MK64F MCU will not be
visible for the USB HID Bootloader application anymore.
After a connection with the USB Bootloader application is established, the STAT LED will be turned on and it will stay
that way as long as the bootloader mode is active. Leaving the bootloader mode will be indicated by the CONN LED,
which will blink once, while the STAT LED will be turned off.
The bootloader mode will be automatically initiated after each power-on event, leading to a five-second startup
delay. To skip the bootloader mode completely and boot-up directly into the normal mode, the CTS pin can be set to
a HIGH logic level after the restart, for at least 100ms. This prevents the five-second delay during the power on if the
firmware update was not intended, shortening the boot-up time before the G2C click is ready to be used.
During the boot-up sequence, the default configuration values will be restored from the internal non-volatile memory.
More details about storing and restoring the default configuration parameters can be found in the
The end of the boot-up sequence will be indicated by a single blink of both the STAT and CONN LEDs, simultaneously.
NOTE:
After leaving the bootloader, a delay of at least 3 seconds has to be made, allowing the connector module to reboot properly.
