Bluetooth Bombs 106
Carey sent in this story that shows Bluetooth still has a few kinks to work out. Bluetooth's universal standard instead seems to be about 10 different standards, and if these companies think they are going get people to buy devices that only work with other devices from the same manufacturer, I think they're in for a rude awakening.

Ponder this idea, maybe some of the vendors, in an effort to seem like team players, are not neccessarily tweaking their devices (hardware, software) to work properly with Bluetooth based devices (hw/sw). By attempting to seem as if they're trying to break into the Bluetooth scene, or be "team players", they're using that status to build around Bluetooth, in an attempt to capture on "the next big thing" (could happen).
Major people are banking mega bucks into this technology which in my opinion will be something like firewire, useless to the typical person.

In France, for instance, it's a military frequency and it remains to be seen if Bluetooth will work reliably there at all. Microwaves and energy saving light bulbs will also cause problems for Bluetooth... From what I understand, the bandwidth is also not too great.

IEEE 802.1 [ieee.org] describes standards for maintence and internetworking of IEEE 802 networks, i.e. spanning tree, VLAN tagging, access control, etc.

IEEE 802.15 [ieee802.org] defines Wireless Personal Area Networks based on Bluetooth v1.1. There is a coexistence task group (TG2) that is defining Collaborative and Non-collaborative mechanisms for information interchange between the WPANs and WLANs.
So now the questions is "why do we need both?" The answer is that WPANs and WLANs solve different problems. WPANs need to be cheap, easy to configure, and very short range. WLANs, on the other hand, should be comparable in range and complexity to a traditional wired LAN.
There is room for both approachs, just as there is room for both ethernet (802.3) and token-ring (802.5) LAN technologies.

Bluetooth over tcp/ip? (Score:4)
For those companies that are desperately seeking to make this all-american dream a reality, I have some advice;
4 layered transmissions
Layers:
1) Identify yourself uniquely, negotiate unique identities with devices conflicting with your identify. (IPv6 using your SN as a mac address, problem solved).
2) Negotiate Public Key Encryption if required -- using IEEE standard encryption algorithm located on chip mentioned at end of this rant.
3) Identify the number of variables people will be working with, ie: "I am a light. I go on or off. My variable is Boolean"; "I am a fridge, I have 3 variables. On/oFF ; Fridge Temperature (range 0 to -20) ; Freezer Temperature (range 0 to -20).
4) Identify how your interface will be displayed to the user. ie; send a pixilated ICON of your device, with the text to go underneath such as "Fridge #56". Identify Whether your variables are straight-listed, or listed in relation to each other such as a linked-tree.
If the device communicating with you has only text ability, then only text will be displayed. It is up to the individual device to decide exactly how the layout goes, so end-users can say, "I don't like the palm pilot Bluetooth interface". This is probably where the problem occurs, everyone wants their product to have scrolling advertisements and look better than someone elses. Yo, you're designing remote controls; get over yourselves.
Last requirement for Bluetooth to work: IEEE implements a Bluetooth RFC database and refuses to IEEE-BT certify non-compliant devices.
In addition to this, all devices wishing to become BlueTooth certified must have a flashable chip in the event of backwards incompatability. If you need to update your bluetooth protocol, you just broadcast the new protocol from any device to all surrounding devices.
I realize this sounds like security risk, since people could flash their own protocols with backdoors or cause major problems amongst the utilities in your house. However when you think about it logically you'll realize this really isn't such a big problem in light of the fact that your Stove, Cell Phone and Maybe even your furnace will all one day be connected to a worldwide WAN known as the internet.
I hope this dream becomes a reality soon, and I wish all you over-funded capitalist pigs luck when Z3ro-c00li0 shuts off your pilot-light and turns on your stove.

In the proprietary world, they are much much worse. The more profit the players anticipate, the worse the problem gets.
The various internet protocols haven't be plagued with nearly that much trouble. At a time when it was so cutting edge that it wasn't even on the corperate radar, it managed to reconcile entirely different character sets and notions of how numbers were stored so that machines that were never intended to interoperate routinely did so. If in doubt, the RFC was the final authority. If the RFC was unclear, this was discussed, and a clarifying RFC was issued to settle the matter.
In the world of proprietary specs, a bunch of companies all haggle and fight over the spec from day 1. Most of the arguements center on "We think it should be this way, and since we're the bestest and the most deserving, you will bow down to our greatness and like it". The result tends to be an ill defined 'standard' with miles of wiggle room and dozens of companies that convince themselves that their ideas were adopted as the cannonical standard.
Rather than holding a quiet bake off where early prototypes are brought out and tested for compatability with a 'lets make this work' attitude, prototypes are jealously guarded secrets.
When the prototypes are finally brought together, it happens at a show with a bunch of crowing marketing people with one or two under-appreciated engineers behind the curtain just in case. The engineers rarely have any authority to make changes, and management's "worst nightmare" is the thought of the lot of them getting drunk together and letting the secrets out of the bag. (That is to say, actually coming to a better understanding of what it will take to be fully interoperable).

What we have here is a perfect example of design by committee and the problems that it causes everytime it comes up. It's simply impossible to be fully compliant with the entire spec so when designing a device so you have to choose which features you're going to support and which vendors you're going to be compatable with.

If 802.11 is good enough then pray tell why is it not being embedded in everything from cell phones to laptops to network appliances.
In the first place it is, 802.11b is being integrated into new laptops as standard. Secondly Bluetooth does not meet that test either, in fact bluetooth does not meet any test because it does not yet exist.
The cost of implementing any electronic gadget is mainly a function of the number of units the development costs are spread over. At the last IETF I went to CISCO were selling 802.11B NICs for $50. I have no doubt that in time the cost will fall the same way the cost of an ethernet nic has plumeted.
Since most of the Bluetooth devices will be AC powered I don't buy the power saving argument. I don't think the extra watts will matter. My pocket PC/ MP3 player / camera / cell phone will definitely have 802.11B so the only portable device I intend to carry had better solve the power problem.
If Bluetooth were ready for prime time today it might just have a chance. As it is it looks like it will be another 2 years at least before it is ready for prime time by which time it will be far too late to have any effect.
Beyond that nobody has yet explained to me why I want to have a conversation with my fridge. I can see why I want my VCR to have a conversation with my Internet connection, but every other incompatibility problem I have could be solved much cheaper by manufacturers agreeing to support a common set of Infra Red remote control commands.
Adding Bluetooth to my VCR does nothing for me. I still need to bluetooth enable my computer to be able to program the VCR when I am out. Bluetooth does not have the bandwidth to send the content upstairs to my office PC so I can watch the program there.

Agreed.
He 'liked' the palm. And the Newton group had a palm-sized Newton with no expandability (just like a palm) at a under-$300 possible price point.
Rather than say 'we have this technology, we can't get palm, lets work with what we have' (this assumes you believe Apple should have been in the handheld space), Jobs worked to drive away almost all the Newton staff.
Statements like this at WWDC 1997:
Jobs - "What does Apple make?"
Jobs bootlickers - 'computers'
Jobs - "What do computers have?"
Jobs bootlickers - 'keyboards'
Jobs - "Than what is this?" and holds up a Newton.
Helped create this:
From the back of the room, MP 130's are turned on, dates is selected and a to-do task of 'find new job' is noted by Newton staff.
First Jobs fired Sandy over a rather bogus charge of 'releasing company secrets' (Sandy told the Newton staff that the spin-in was going to happen). And when the spin-in happened, 32 of the Newton engineers left in mass for palm. Jobs was then able to say to sockholders etc all that "We had to kill the product. We had no staff to build it". The people who remained were the ones who were the ones who did NCU. The NCU was 1.5 years late, would not work if you have over 2 gigs of free disk space, and only syncs with long-dead PIMs. (AKA Palm got the cream...)
Had jobs GOTTEN the palm product from 3com, the palm staff would have quit on Jobs again. Thus palm would be dead by now, and the handheld of choice would be Windows for Pen.

Interoperability _is_ the standard (Score:1)
This is easy today when there are few if any devices to test against, but apart from some 1st generation mishaps which could call for an upgrade, a bluetooth device should work with any other device.
In reality I share your fears that interoperability is an exponentially growing problem still to be solved. The simple protocols in bluetooth won't reach all the way, and even that will be a tough to get working. In the end Bluetooth will only be a carrier of the compete anarchy of XML content... Lets hope for a better standard than "what M$ do"

I apologize for not having a link for backup, but part of my online wanderings last week ran across mention that issues around Bluetooth in France and Japan had been settled. This is just conjecture, but it might have something to do with the power of the signal as much as the frequency it is operating on.
A quick online search ran across a number of articles with headlines such as "France legalizes Bluetooth". Here is one link [ebiquity.org] talking about it. Hopefully, that settles the issue. I'm not sure what the current status of 802.11 in France is.
Just for the hell of it, here is another shameless plug for my Bluetooth on Linux [matlock.com] information page. Our favorite free operating system will be on the front line of new wireless technology.

I believe "pushing the boundaries" is the reason this project isn't working. If I personally felt like having my palm pilot connect to all devices in my house; I wouldn't want to be looking at shiny corporate graphics describing each appliance as being a Maytag, GE and colourful SONY stereo with scrolling graphics. I would want a little box called, "light" that actually controls my light when I click on it.
Pushing the boundaries in the way you're suggesting is about as exciting and useful as "pushing the boundaries" in the artistic appeal of the buttons on your microwave; in the end - nobody cares.
And in the end, working on math routines and vector-plotting standards accross all devices would increase the weight of your Bluetooth powered watch to 6 pounds. Anything more than an absolutely simple matrix of on and off pixels isn't going to work with anything.
Companies themselves, and devlepers; looking to improve the interface to Bluetooth devices can add their own colorful icons to their display, but in the end, if the PROTOCOL isn't simple, nothing will work together.

IEEE shouldnt even allow anyone to use the name bluetooth unless it complies 100% with the spec, not 99% and not 101%. No mention of the term in marketing or product materials, nothing.
And anyone who does do so without being compliant should be sued into the ground and hunted down like rabid dogs. And have their IEEE memberships stripped of course.
Oh forget it... the very idea of ethics in people who design devices for people that are supposed to work... ha!

Wireless lans, well duh, you'd also need a bit more range for bluetooth to be useful there (and 802.11b is already going to be king).
But printers/scanners... hmmm, are you sure there's not enough bandwidth for that?
HP just announced their first bluetooth printer at CeBIT:
"The HP Deskjet 995C inkjet printer, the company's first integrated Bluetooth printer, allows users to print without cables from up to 10 meters (approximately 30 feet) away from other devices enabled for Bluetooth printing."
They've also got several other bluetooth projects going on.

Regardless of what all you AC's (with heavy emphasis on the coward part) are posting about, I still stand by what I said originally. The statement made by the bluetooth developer doesn't make any sense. That was all I was trying to point out. If you want irony, there's irony in this case of a post about someone not making sense being replied to in such an incomprehensible and nonsensical manner. That's where the first bit of irony is.

Huh? Why would the inkjet need to send data back to the computer? AFAIK, bidirectionality (in the case of printers) is only used for sending back the name of the printer. Cute, but not vital for operation.
Now, for other parallell port devices, such as scanners or Zip drives, you would have a point.
> How about 5 1/4 floppy drives? Remember not being able to read 360kb formated floppies in certain high density drives?
This actually had more to do with the order in which the disk was written to in the various drives, rather than with the drives themselves. Alternatively writing to a disk in a HD drive and a DD drive was a definite no-no, and would make the disk unreadable in the DD drive. The reason for this was that the R/W heads for the DD drives where twice as large. When writing using the DD drive, you would get rather wide tracks. When then writing using the HD drive, the new data would be superimposed as a narrower track, whereas the sides still had the old data. No problem reading such a disk in a HD drive: indeed, due to its narrower head, it would only pick up the new data. The DD drive, however, picked up a mix of both signals and hence could not make any sense of the data.
The easy solution: when transporting data between two computers where one had a HD drive and the other a DD drive, keep two disks: one for transfers from the HD drive to DD, and one for the tranfering in the other direction. Both had to be formatted to DD of course.
