BlueRadios, Inc. and Stonestreet One introduce BlueBridge BR-LE4.0-D2A, a self-contained Bluetooth 4.0 dual mode low energy module which utilises the Texas Instruments CC2564 base band chip, integrating antenna, radio, MSP430 microcontroller, and fully integrated Bluetopia software stack into an 11.8x17.6x1.9mm package. In addition, BlueRadios is introducing a pin-for-pin compatible nBlue BR-LE4.0-S2A single mode nano ampere network module with the TI CC2540 processor. Both modules are fully compliant with FCC and CE EMC requirements.

Both of these low energy modules require no external supporting components and are small enough to fit into highly space constrained applications, such as watches, health and fitness sensors, remote controls and key fob style devices. The firmware design allows the modules to be controlled by an external microcontroller using AT commands or by custom applications loaded directly onto the module.

Bluetooth low energy, part of Bluetooth ver4.0, specifies two types of implementation: single mode and dual mode. Single mode chips implement the low energy specification and consume just a fraction of the power of classic Bluetooth, allowing the short-range wireless standard to extend to coin cell battery applications. Dual mode chips combine low energy with the power of classic Bluetooth and are likely to become a de facto feature in almost all new Bluetooth enabled cellular phones and computers. Since Bluetooth low energy technology is an interoperable standard, the BlueRadios modules will be able to communicate with both single and dual mode devices from all manufacturers.
