12.2 Bluetooth UART interface

The Sterling LWB+ uses a single UART for Bluetooth. The UART is a standard 4-wire interface (RX, TX, RTS, and CTS) with

adjustable baud rates from 9600 bps to 4.0 Mbps. The interface features an automatic baud rate detection capability that

returns a baud rate selection. The baud rate may be selected through a vendor specific UART HCI command to a value other

than the default rate of 115.2 kbps.
