Before You Begin 2i Congratulations on your purchase of the TDK Systems blu Module. The Module is designed to be built into a device and to provide a simple, low cost Bluetooth interface. The module is designed to integrate with a wide range of applications and platforms with a simple electrical and software interface using AT commands. This guide aims to provide all the electrical and mechanical information 2i needed to design applications using the blu Module. A separate 2i docum

1 Functions 2i The blu Module contains a complete Bluetooth interface and requires no further hardware to implement full Bluetooth communication. The module has an integrated, high performance antenna together with all RF and Baseband circuitry, it interfaces to the host over a straight forward serial port using AT commands. The module runs specific firmware within the Virtual Processor that includes a serial Port Profile and AT command interpreter. The module can be configured so that

2 Application Interface 2i The blu Module is equipped with a 40-pin 0.5mm pitch board to board connector that connects to the application platform. Electrical and mechanical characteristics of the board-to-board connector are specified in Chapter 3. • Serial interface (see Section 3.0) • Electrical specification of the interface (see Section 3.1) 2.1 Serial Interface UART_TX, UART_RX, UART_RTS and UART_CTS form a conventional asynchronous serial data port. The interface is design

It must be able to provide sufficient current in a transmit burst which can rise to 65mA. The module includes regulators to provide local 3.3V and 1.8V. These rails are acces

example when the supply voltage to the module experiences a Brown- Out (momentary dip in the supply voltage level), or a rapid power cycle i.e. the power is switched off and then on within 1second, there is a possibility that the module can enter an unknown state of operation. It is strongly recommended that the application hardware onto which the module is mounted provides a Power-On-Reset circuit with a Brown-Out detection capability. This will guarantee that under all circumstances the

2.4 SPI Bus The module is a slave device that uses terminals SPI_MOSI, SPI_MISO, SPI_CLK and SPI_CSB. This interface is used for program firmware update. Note: The designer should be aware that no security protection is built into the hardware or firmware associated with this port, so the terminals should not be permanently connected in a PC application. 2.5 Parallel PIO Port Five lines of programmable bi-directional input/outputs (I/O) are provided. GPIO[1:5] are powered from VCC

Notes: • UART_RX, UART_TX, UART_CTS, UART_RTS, UART_RI, UART_DCD and UART_DSR are all 3.3v level logic. For example, when RX and TX are idle they will be sitting at 3.3V. Conversely for handshaking pins CTS, RTS, RI, DCD, DSR a 0v is treated as an assertion. • Pin 6 (UART_RI) is active low. It is normally 3.3v. When a remote device initiates a connection, this pin goes low. This means that when this pin is converted to RS232 voltage levels it will have the correct voltage level for

2i 4.2 Mounting the blu Module onto the application platform There are many ways to properly install the Module in a host device. An efficient approach is to mount the PCB to a frame, plate, rack or chassis. Fasteners can be M1.8 or M2 screws plus suitable washers, circuit board spacers, or customized screws, clamps, or brackets in 2.2mm diameter holes. Note that care should be taken to ensure the head of the fixing does not interfere with the circuit. Nylon fixings are recommended. In

In addition, there are certain S Registers which have a direct impact on power consumption, which are described next. 2i The blu Module has 2 LEDs which can be configured to display connection status. One led is used to display connection status, while the other is used to either display ‘Ring Indicate’ statu

It is possible to reduce the duty cycle down to as low as 0.5% at the expense of response time. The response time can be specified via S Registers 508 and 510 for page and inquiry respectively, where the worst case response time can be as high as 2.5 seconds. Then the duty cycle can be varied by changing the value of S Registers 509 and 511 appropriately. For example, if S Register 508 and 510 are both set to 1000ms and S Register 509 and 511 are both set to 11ms then the duty cycle is

contacted during N-M slots, and so can switch its power hungry circuitry off. The specification goes further by also specifying a third parameter called ‘timeout’ (T) which specifies ‘extra’ timeslots that the slave will agree to listen for after receiving a valid data packet. Put another way, if a data packet is received by the slave, then it knows that it MUST carry on listening for at least T more slots. If within that T slot time period another data packet is received, then the timer i
