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. -
Bluetooth 4.0 Spec Adopted
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." -
Nokia's Wibree Takes on Bluetooth
narramissic writes "Nokia has developed a new, short-range wireless technology, called Wibree, that it says is a lot more power efficient than Bluetooth, which means it could be used in smaller and less costly devices. It can also use the same radio and antenna components as Bluetooth, helping keep costs down further. Wibree could compete with Bluetooth in the workplace as a way to link keyboards and other peripherals to computers. But it could also have more interesting applications for consumers, in devices such as wrist watches, toys and sports equipment." What does this say about Bluetooth, considering Nokia is a member of the Bluetooth Promoters group? -
Bluetooth Shipments Exceed 1M per Week
An anonymous reader writes "Just when you think that Bluetooth is dead... The Bluetooth SIG releases a press story that quotes some pretty impressive figures - over 1M Bluetooth enabled devices have been shipped within a week. Bluetooth wireless technology has been quietly making progress over the past year and can now be found in an impressive array of consumer products, from mobile phones and headsets to PDAs, PCs, MP3 players and even automobiles. The technology has reached critical mass, with several books on how to write your own applications with the technology, including Java for those of you who want to create your own Bluetooth apps for your SonyEricsson P900" -
The Death of Bluetooth?
Aaron Cherrington writes "Bob Frankston has written an article in which he declares that Bluetooth has failed. The article states that despite the fact it is wireless, it still has all of the limitations of wires. Is it too early to declare the death of Bluetooth, or can we can expect more out of it?" -
The Dream Handheld
Reader samjam sent in an interesting piece about his dream handheld PC, sort of a cross between a subnotebook and a wireless web pad, with the kitchen sink thrown in. Mmmmm, light-emitting polymers. I can't decide if this kind of thing is right around the corner or just a fantasy - after all, normal notebook computers sell, and at a nice high premium - and web pads are less than successful - why would anyone spend the money to develop a device like this? samjam writes: "My dream handheld is not available though some things come close. The technology is becoming available.Though it may take a few months, here is what I would put together if I had the chance. Including Bluetooth, IButtons, solar panels and light emitting polymer screens...
For links to other linux handhelds, try linuxdevices.com.
My ideal handheld is the size of an A4 pad of paper, so I have to hold it on my left forearm with the fingers of my left hand curled over the end. A4 gives me plenty of screen space for watching real TV, reading real books, writing real emails, browsing real web pages and doing some real showing off.
The front cover is a solar panel, but I can't decide if the cells should be on the inside or the outside to help charge it while I use it or while I'm not using it. Hard one that.
The screen is not heavy-breakable LCD but LEP (brief technical primer, more on Google) or perhaps Xerox Electronic Paper seemingly available under the name Gyricon, pictures here and slight details here.
The choice of processor doesn't bother me much; I'd like to think there are many versions available of my handheld by many manufacturers (to drive the price down) and so many processors will be available but let's pretend the first release will run on a Transmeta just to keep excitement running high.
60 GB or so should be plenty of disk space, 2.5" IDE to keep weight down.
Input via stylus or sticky finger of course, with support for Graffiti, as used on the Palm and many others, also Quickwriting as featured on Slashdot as well as regular handwriting recognition (take your pick) and other pluggable input modules with popup keyboard for those times when you just can't manage to input a tilde (~) or backtick (`) properly.
Connectivity will be provided via a multitide of USB ports (where real keyboards can be plugged), Bluetooth (useless link) in action (good link), wireless ethernet as well as perhaps as many as 4 PCMCIA slots for things that change a lot like GPRS adaptors &c, or radio and TV tuner cards. Yeah! Why not add some Compact Flash while I'm at it? And boring 100 base T ethernet.
In fact I'm going to use the mobile phone card, along with my sound system to make the whole thing into a mobile phone for voice, not just data access. Talking of phones, the built in web cam can be used for video conferencing with (for example) Gnophone.
Better stick some firewire ports on there, too, for good measure, along with a few IRDA ports pointing in a few different directions for those more subversive inter-classroom networks as well as controlling my grannies telly to show off. And talking to my old non-bluetooth mobile which I can't afford to upgrade cos I spent it all on my handheld.
It will have integrated Ibutton support for security and authentification, maybe even built into the BIOS.
What more do I need? Oh yes, an Operating System. Pick your own.
I shall be running Linux with Ximian Gnome because it looks cool (and Bill Gates was nearly right, eye candy counts for a lot if only not to distract you by means of ugliness). I will be running redhat because I find up2date (or redhat channels of RedCarpet) invaluable effort-free way to remove those exploits, and I will finally get round to playing with Rebol.
The first thing I will need to develop is some network scavenging software to grab internet connectivity where it can for syncing imap folders and news, updating "offline web pages" [yikes! MS concept there]. Code to hi-jack available SMTP relays (*cough*). Does this smell a bit like Jini or something like it? I'll need to register my changing location for Gnophone so callers can find me. Perhaps the first thing for company visitors in the future will be to checkin their Ideal Handheld to the company network.
I will load all my favourite books into it as well as the entire classical Mormon works, copies of conference talks Doctrines of Salvation, Journal of Discourses etc, along with the Bible, Book of Mormon, and all of Project Gutenberg.
What will you do with yours? Have I missed any gizmos out? Or gadgets even?"

Will 802.11 Kill Bluetooth?
joshwa writes "NYTimes (free reg. required) has an article about the struggles of the Bluetooth folks to fine-tune their technology and get the costs down far enough. The most interesting part is that analysts seem to think that 802.11's (what is this new 'Wi-Fi' moniker?) growing popularity will overshadow Bluetooth's entrance into the marketplace, and will beat Bluetooth into the small devices market. Can 802.11 actually work in a Palm or a cell phone?" The article, IMHO, misses the difference in uses - if you've got a small device that you want to conserve power on, and only communicate small distances, Bluetooth's ideal. If you've got a lot of power, a la a notebook computer, and want to communicate 150 ft., then 802.11 is what you want. Imagine that: Different uses! Different standards! Amazing! -
Bluetooth for Linux Released
Bjorn Wesen writes, "A GPL'ed Bluetooth driver for Linux has been released by Axis Communications, supporting the current Bluetooth LAN-profile (PPP over Bluetooth). The download and mailing lists are at their developer site. This will become useful especially for embedded/mobile Linux devices - and to push Linux into the new technology before The Other OS. " Bluetooth has been getting a /huge/ amount of attention from the technical press, as well as the mainstream press. It looks to be one of the most promising standards for short-length wireless communication devices and drivers for Linux is a good thing to get this early in the game.
