adeelarshad82 writes "The Bluetooth SIG announced the formal adoption of Bluetooth Core Specification Version 4.0, which begins the qualification process for new, low-power devices. Bluetooth 4.0 [zipped PDF of the spec] was formally announced in April, and added a new, ultra-low-power aspect to the short-range personal-area-network technology. According to the SIG, the new 4.0 core specification should allow devices to run on coin-cell batteries for years with a new ultra-low-power duty mode."

    Do you think people will just throw away most of the little bluetooth devices that use this new low power spec when the battery runs out rather then going out to replace the batteries, as is so often the case with small consumer electronics like cheep watches? Maybe this will promote planned obsolescence in those sort of accessory devices.

    That's nice, but are the interference issues between WiFi and Bluetooth fixed yet?

    It would be nice to have the laptop connect to the stereo via Bluetooth while I'm lounging in the living room without cutting out while I'm watching YouTube.

    Given that "smart meters" will inevitably end up being connected to billing, I wouldn't be too optimistic about there being any fully open standard for how they do their reporting. They will probably use some sort of mostly-standard transport(ie. bluetooth, wifi, TCP/IP over whatever is handy) for economic reasons and, for similar economic reasons, we might end up with some sort of "industry consensus" type standard, where the equipment is more or less interoperable; but the details are rather hush-hush/professionals only(if, probably, more transparent than they would like to anybody with hardware hacking chops and some guts).

    If one is lucky, they would probably make mostly-standard use of the bluetooth serial profile, the way that bluetooth GPSes do, with some additional commands tacked on to allow for configuration, and (ideally) to make the device spit out a nicely formatted description of exactly what information it is providing.
