The consortium behind the Bluetooth wireless standard announced Tuesday that Nokia Corp., the world’s largest maker of cell phones, is contributing a technology that promises to bring the wireless connections to devices that are too small for regular Bluetooth chips.

The technology, called Wibree, opens up the possibility of a host of small wearable gadgets, like watches, heart rate monitors, pedometers and pill boxes that communicate with Bluetooth-equipped cell phones or computers. A watch could display the user’s incoming text messages, for instance, or an action figure toy could sense the presence of other toys.
