User's Manual

Section Two: Bluetooth User
This module is used a standard UART interface for communicating with other serial devices.
BlueCore5 Multimedia External UART interface provides a simple mechanism for communicating with other
serial devices using the RS232 protocol.
When BlueCore5 Multimedia External is connected to another digital device, UART_RX and UART_TX
transfer data between the two devices. UART configuration parameters, such as baud rate and packet format, are
set using BlueCore5 Multimedia External firmware.
Note:
To communicate with the UART at its maximum data rate using a standard PC, an accelerated serial port
adapter card is required for the PC.
Table 1: Possible UART Settings
The UART interface can reset BlueCore5 Multimedia External on reception of a break signal. A break is
identified by a continuous logic low (0V) on the UART_RX terminal, as shown in Figure2. If tBRK is longer
than the value,defined by the PS Key PSKEY_HOSTIO_UART_RESET_TIMEOUT, (0x1a4), a reset occurs.
This feature allows a host to initialise the system to a known state. Also, BlueCore5 Multimedia External can
emit a break character that may be used to wake the host.
FCC Warning statement:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This
device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
