Bluetooth Gains Direct Internet Access, Security Enhancements

jfruh writes: The Bluetooth spec never quite became the worldbeater it was billed as, but it's aiming to become indispensible to the Internet of Things. Updates to the spec make it possible for low-powered Bluetooth devices to gain direct access to the Internet, and, perhaps more importantly, make those devices a lot harder to hack.

Reading comprehension.

They have made updates to the spec. Those updates make devices following that spec harder to hack and allow internet access.

DRTFA and BRTFS but I can give you an few lil tidbits about this:

1) Everything connected to the internet is connected to a router somewhere along the line... that's not interesting.
2) There are a lot of ways to connect to the internet that have absolutely nothing to do with WiFi or 3G.
3) Right now a Bluetooth device can connect to another device. That device may provide a variety of services for said Bluetooth device including providing network connectivity BUT that device isn't really connected to the Internet itself. The new spec provides this device to be connected "more directly" to the net as in it will have its own IP address. The router that it is connecting to supporting the BT4.2 protocol is really no different from the WiFi access point your WiFi equipped device is talking to. Just need to add to the alphabet soup: a,b,g,n,bt

How is this "directly connected to the internet" when it is using a router to access the net.

By that definition, NOTHING connects directly to the internet.

Anyone with a better understanding care to explain ?

The proper definition of a host running an internet-facing application being "directly connecting to the internet" is using IP for the first hop, with the packets having a route from there to and from the rest of the Connected (capital-I) Internet.

Bluetooth 4.2 added support for IPv6 to/from bluetooth devices. This means IP packets formed on, or directed to, the Bluetooth 4.2 hosts, for delivery to/from other Internet-connected devices, do not require a protocol-translation gateway to select and translate some subset of the packet types, services, and features, modifying the transport semantics to support some tiny subset of functionality that the gateway explicitly understands. An IP packet formed on the bluetooth device goes all the way to its destination semantically unmodified, and ditto packets going from some other device to the bluetooth device. The full feature set of IP (or as much of it as the stack implementer choses to support) is available, while the routers can be "as dumb as rocks" and totally ignorant of what the application on the Bluetooth device is up to, in classic Internet style.

A Bluetooth 4.2 device, using IPv6 and with a route, IS on the Internet, and is a peer to all other internet-connected hosts.
