CSR demonstrates Bluetooth low energy transfer
The demonstration showed the two Bluetooth low energy devices transferring data to the handset using a Bluetooth low energy advertising packet without any prior configuration or pairing. When a button is pressed on the weighing scales the embedded Bluetooth low energy radio wakes up and sends a short burst of data to the handset. The temperature sensor transmits data continuously. The name and value of both sensors are then simultaneously displayed on the phone. The application automatically updates the display with the new value each time a new advertising packet is received.
The mobile phone handset was modified for the purpose of the demonstration to incorporate CSR’s BlueCore7 dual mode silicon (Bluetooth low energy and Bluetooth v2.1), and a Java API and MIDlet application to provide a simple user interface for displaying the information received.
Bluetooth low energy (previously known as Ultra Low Power Bluetooth or Wibree) is designed to be used to transfer simple data sets between compact devices. The technology uses fewer frequencies (3 rather than 32) to make connections compared with standard Bluetooth, resulting in lower power consumption when connectable
We know you’re not really down with digesting any more catchphrases, but the technology formerly known as Ultra Low Power Bluetooth / Wibree is now being dubbed Bluetooth low energy. Now that we’re clear on nomenclature, you may be thrilled to know that CSR showcased its recently unveiled BlueCore7 dual mode (Bluetooth low energy and Bluetooth v2.1) chip at a Bluetooth SIG Medical Working Group meeting. According to onlookers, the handset was able to transfer data to another nearby mobile using just 3 frequencies rather than 32, resulting in an unquantifiable decrease in power consumption. Sounds like a winner on the surface, but we have this weird feeling that mass adoption of this tech is like, years away.
