The board is somewhat confusing as it contains two mcu's. The actual module is a BL808 but there is also a BL702 which acts like a debug and usb-uart. The UART USB port is connected to the BL701 and provides serial interfaces. The OTG port is connected directly to the BL808.

The boot button can be used to boot either of the MCU's into firmware update mode. Press and hold while connecting the power and the BL702 can be flashed. Press and hold boot while pressing reset and the BL808 is starting in firmware update mode.
