The UART causes 1.25mA current consumption in sleep mode when left enabled. That's a massive power drain! While the application could disable the UART, it seems better to fix this directly in the bootloader.

It is left enabled by the Wasp-OS bootloader. Disabling it gets us back
to the baseline current consumption.
