Before Y ou Begin Congratulations on your purchase of the TDK Systems blu 2i Module. The Module is designed to be built into a device and to provide a simple, low cost Bluetooth interface. The modul e is designed to integrate with a wide range of applications and platforms with a simple electrical and software interface using AT commands. This guid[...]

Functions 1 The blu 2i Module contains a complete Bluetooth interface and requires no further hardware to implement full Bluetooth communication. The module has an integrated, high perform ance antenna together with all RF and Baseband circuitry, it interf aces to the host over a straight forward serial port using AT comm ands. The module runs spec[...]

Application Interface 2 The blu 2i 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 bo ard-to-board connect or are specified in Chapter 3. • Serial interface (see Section 3.0) • Electrical specification of the interface (see Section [...]

It must be able to provide sufficient current in[...]

example when the supply voltage to the module experiences a Brown- Out (momentary dip in the supply vo ltage level), or a rapid power cycle i.e. the power is switched off and th en on within 1second, there is a possibility that the module can ent er an unknown state of operation. It is strongly recommended that the application hardware onto which t[...]

2.4 SPI Bus The module is a slave device that uses terminals SPI_MOSI, SPI_MISO, SPI_CLK and SPI_CSB. This interf ace is used for program firmware update. Note: The designer should be aware that no security protection is built into the hardware or firmwa re associated with this port, so the terminals should not be permanently connected in a PC appl[...]

Electrical specification of the interface 3 The Hirose DF12C board to board connector on the module is a 40 way double-row receptacle. The pin allocation is as follows: Pin Signal Description Pin Signal Description 1 Analogue 0 1.8v Max 2 GPIO1 I/O for Host 3 Analogue 1 1.8v Max 4 GPIO2 I/O for Host 5 SPI_MISO SPI bus serial O/P 6 UART_RI ‘Ring?[...]

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, R I, 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 [...]

4.2 Mounting the blu 2i Module onto the application platform There are many ways to pro perly 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 customiz ed screws, clamps, or brackets in 2.2mm diameter[...]

It is possible to reduce the duty c ycle down to as low as 0.5% at the expense of response time. The resp onse time can be specified via S Registers 508 and 510 fo r page and inquiry re spectivel y, where the worst case response time can be as high as 2.5 seconds. Then the duty cycle can be varied by changing th e value of S Registers 509 and 511 a[...]
