Bluetooth may at last be delivering on its initial promise, but a new series of unexpected hurdles have beset the technology, DigiTimes reports.

Demand for the chips that power Bluetooth devices has been exceeding supply by 30 per cent since the end of the third quarter, and this demand will not abate before the end of the year, the report claims quoting Bluetooth module manufacturers.

The shortage is global, with demand for Bluetooth devices expected to reach 65 million to 70 million units this year, up from 30 million last year, and predicted to climb again to reach 130 million units next year.

In related news, Apple released an OS X Bluetooth software update last night. This is available using the Software Update feature.
