Firmware update for DK Tank

Additionally, after flashing DK Tank, you may need to update the settings file settings.ini on the microSD card. If necessary, download the settings file corresponding to the firmware version or the version below.

Without replacing the settings.ini file, all the new parameters that appear in the file will be so have a default value. Therefore, you can ignore the update of settings.ini, or add new parameters manually. Information about the added and renamed parameters will be described in the changelog for the new version.

In this case, the DK board must be forced into bootloader mode. To do this, hold down the button on the DK board, then connect the USB cable and apply power. The board will go into bootloader mode, the indicator on the board will blink frequently. Then release the button. The DK App will display the device name as "bootloader". Then you can update the firmware as usual.
