    Bluetooth and regulatory approvals. A list of the countries where the module is approved will be provided by TDK Systems as required. As a minimum the product is listed in Europe, Scandinavia and USA. TDK Systems assumes no liability for customer failure to comply with national RF approvals.

  • Page 4: Functions

    Functions 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.

  • Page 5: Application Interface

    Application Interface 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) •...

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.
  • Page 7 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.

  • Page 8: Spi Bus

    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.

    4.2 Mounting the blu 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.

    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.
  • Page 20 This will allow the master to interleave the sniff modes for all slaves attached. For this reason, the sniff parameters are specified in TDK module via four S registers. S Register 561 is used to specify ‘N’, S Register 562 is used to specify ‘T’...

When an incoming connection is detected it will be asserted, until the connection is either answered or rejected using ATA and ATH respectively. See S Registers 552 & 553 for more details PIO3 (DCD) will be deasserted when the device is in the unconnected state.
