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.

Note:

The DFU boot loader must be loaded into the Flash device before the UART or USB interfaces can be used.

This initial flash programming can be done via the SPI.

Federal Communication Commission Interference 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.

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.
