BGB203 BT 2.0 Serial Port Profile Module User’s Guide
3.
Functional Overview
The 1SPP firmware builds on the strengths of the Philips’ BGB203 SIP and adds the
Serial Port Profile to the module. This provides a low-cost, low-power, highly
configurable, serial cable replacement option. The 1SPP module follows the Bluetooth
standard and is qualified by the Bluetooth SIG.
The 1SPP firmware is controlled by input received on the UART interface. To make
development quicker and easier, the format of the input follows the typical format that a
modem accepts. All commands are prefixed by the AT prefix. Figure 1 illustrates the
overall architecture of the 1SPP firmware/BGB203 combination.
To design the 1SPP module into a product, the designer should follow the same board
layout and connections as for the BGB203 SIP in any other design that uses the UART
interface to communicate with the Bluetooth controller. This provides the basic
communication to the 1SPP firmware. If the design also calls for the more advanced
input and output features of the firmware, additional GPIO lines will also need to be
connected. The advanced features that require additional connections include the
modem signals (CD, RI, DTR, and DSR) and the active connection output. The following
table lists the GPIOs that are used by the 1SPP firmware for the advanced options:

Description
Used for testing and to calibrate RXTUN
Carrier Detect signal (direction depends if the
device is configured to be a DCE or DTE
device)
Ring Indicator signal (direction depends if
device is configured to be DCE or DTE device)
Data Terminal Ready signal (direction depends
if device is configured to be DCE or DTE
device)
Data Set Ready signal (direction depends if
device is configured to be DCE or DTE device)
Active high when there is a Bluetooth
connection. Low when there is no Bluetooth
connection.
The remaining connections that are used by the 1SPP firmware are the UART transmit,
UART receive, and UART flow control signals (RTS and CTS). Please see the BGB203
datasheet for more information on the above listed input and output features. Note that
all signals (except for UART transmit and UART receive) are not required, and are only
required if the device is configured to support the required functionality.
