6.2 Using UART

The Bluetooth controller has a Boot ROM that starts execution as soon as the device is powered up. It is used to receive the firmware, download it to the instruction memory and trigger the controller to start executing it. The Boot ROM runs initially at 115200 bps baud rate, and flow control is disabled. If the Bluetooth firmware is already running on the CPU, do not download firmware.
