We haven't heard much about Wibree
lately, but the next-gen Bluetooth standard looks to be humming along nicely, with a name change to ULP (Ultra Low Power Bluetooth) and now a dual-mode chip from CSR that supports Bluetooth 2.1 and ULP on the same silicon. The chip consumes 10 times less power than a standard Bluetooth unit while connecting, and 50 times less power during data transfer, as it's essentially a stripped down version of Bluetooth with way fewer frequencies to worry about. This dual-mode chips means we won't have to leave the superior bandwidth of Bluetooth 2.1 behind. The chip should be available in the market sometime in 2008.
