  • Page 3: Before You Begin

    Before you 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 module is designed to integrate with a wide range of applications and platforms with a simple electrical and...

  • Page 4: Functions

    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 performance antenna together with all rf and baseband circuitry, it interfaces to the host over a straight forward seri...

    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 recomme...
