To my knowledge, the word "promoter" means someone in the second line of development. Either someone funding, or advertising it.
For example, a promoter of art is usually some rich guy, not necessarily the poor chap, who actually paints the pictures.

I think what they're trying to say is that with Bluetooth being standardized, they're perfectly happy to depend on 3rd-party manufacturers to make the peripherals. I imagine this is a way for them to focus on their core business and not get too involved in something ancilliary to it.

"Promoter" is a membership level (the highest one, Ericsson did came up with the technology after all) of the Bluetooth SIG, and this seems to be the context of the quote.
Also notice that it says "chip" customers. The 2nd article mentioned Ericsson will still do software development.
I think you've hit the nail on the head. The article states that Ericsson will no longer be making products for the semiconductor market- ie, they will no longer be making Bluetooth CHIPS. It has probably become more economical for Ericsson to buy said bluetooth chips from other (probably Chinese or Taiwanese) vendors and integrate them into their mobile devices instead of producing the chips they integrate themselves.
And this is nothing but a good thing, as it means that the Bluetooth implementations have become uniform to the point that Ericsson can trust other manufacturers to make the chips that they use.
While the majority of the comments for this article seem to be ringing the death-knell for Bluetooth or at least proclaiming that Ericsson has lost faith in the technology, you correctly show that this couldn't be further from the truth.

Glass Half Full Interpretation: Maybe this means that Bluetooth has become so simple to implement that they don't need a dedicated development team anymore. It seems that Bluetooth is cropping up in all sorts of CE devices. BT chips and control sets are becoming more and more standardized. For Ericsson, the hard work of developing tie-ins to their phone OS is already done. This could be a good sign, rather than a bad one, for Bluetooth in general.

I'm a little fuzzy on the relationship between Ericsson and SonyEricsson.
Also, what's the relationship of Sony to SonyEricsson? I've had a lot of frustration with Sony and Bluetooth support in the USA.
Sony Ericsson Mobile Communications was established in 2001 by telecommunications leader Ericsson and consumer electronics powerhouse Sony Corporation. The company is equally owned by Ericsson and Sony.
I always like the idea of Bluetooth, though I'm afraid I saw this coming. I don't know why it was never adopted on a wider scale, but I certainly hope that other short distance wireless technologies (like WUSB) do take off. It would be nice to have a desktop with no wires except for power.
No effect at all. JVC invented the VHS standard, it's small market share was not signifigant in it's adoption. Phillips invented the redbook audio CD, it's influence is miniscule today, or even 15 years ago.

Well, according to both of the articles it's the research team that created Bluetooth, and the technologies around it. They are not the group that is responsible for incorporating Bluetooth into the other products.
It could be as simple as "the standard has been set, the goals have been accomplished, move on to new things." Since Ericsson is no longer the sole creative force behind Bluetooth, it makes financial sense to not keep 125 people employed to argue one seat on the Bluetooth Special Interest Group.
It's too bad for Bluetooth in that I think Ericsson had some brilliant visionaries doing this work, and that those people are no longer focused on Bluetooth. However, they're being incorporated into other units which can only help them overall.
It's not good news, it's not bad news. It's just news. The timing is interesting as I see Bluetooth now on the cusp of adoption by every cell phone maker for their mid- and possibly even low-end phones.
( And Michael, wi-fi is not necessarily a good replacement for Bluetooth. The higher power requirements for wi-fi mean shorter battery life, which is death for cell phones. And Bluetooth incorporates discovery protocols which are all geared toward personal networking, not internet networking.

How about a wireless speakerphone in your car? With a Bluetooth handsfree kit, you can just hop in your car and go. Your car and your phone recognize each other as you turn on the ignition, and your car says "I'm going to be your headset now."
It's been discussed having Bluetooth "silencers" installed at movie theatres, concert venues, and restaurants. They'd be a simple Bluetooth device that would request your phone switch to a silent profile for the next hour or two. If you were an anti-social jerk, you could turn such a thing off. But as we know from lots of experience, most people won't be bothered to change their default settings. It's not a complete solution to the problem of cell phone ringers in auditoriums, but every phone call silenced makes for a more pleasant experience for all.
The nice thing is that all of the features you mention with respect to PC usage can quite peacably coexist with the cell phone usage. Both ends can drive the market simultaneously, and as more crossover functionality becomes possible, consumer demand will drive more adoption. We're already seeing this with digital camera phones exchanging pictures with PCs. And laptops are able to use the Bluetooth equipped phones for network access.
Bluetooth was the sole reason I purchased a T637 phone earlier this summer. I really didn't care about the camera (crappy quality pictures) nor about the Java in the phone. I wanted my Palm Tungsten to be able get to the internet occasionally, and I now have that. But I also have the option to have a speaker kit in my car (I suppose this will wait 'til Christmas), to exchange address and phone data with my desktop, and opens up all sorts of possibilities.

In typical Slashdot function, we see people sitting here typing away responses about how useless bluetooth is for wireless-whatever due to its short range. Unfortunately for those people, they never realized that bluetooth is a wire-replacement technology. When I have my cell phone on at my desk, I don't want to feel like I am sitting in a hospital ICU bed with a bunch of wires hanging off my body. Instead, my bluetooth headset takes care of that part. Also, at my current location, internet access via Edge is far more useful and cheaper than buying DSL. So it serves two purposes right there that 802.11 is too killer for. Also, sync'ing my PDA is much easier than having to drag a craddle with me everywhere. My point is that SE is only moving their bluetooth operations under another division so bluetooth is not going anywhere and I am glad. 802.11 is too power hunger for the things I need to get done. Lastly, big manufacturers such as Dell are doing away with ALL legacy ports such are IrDA, Parallel, Serial, so we are left with firewire, USB, and bluetooth. Out of those, bluetooth makes the most sense.

The short range may have something to do with it.
If you think that's a liability, you really don't understand the hallmarks of bluetooth and what its purposes are.
Bluetooth has become commoditized; it's in the hands of low-cost chip manufacturers. That makes it uninteresting for a company like Ericsson and they are better off just buying whatever BT technology they need cheaper from elsewhere. If anything, that's probably a sign of maturity of the technology.
You haven't used Bluetooth have you? Or maybe you just had a bad experience. I don't know. What I do know is that Bluetooth is a feature I now regard as indespensible in my phone, pda and, soon, headphones. I won't even consider a phone, pda or laptop without it now.
My phone and PDA (nokia 6310i and Palm Tungsten T3) essentially act as one device thanks almost entirely to bluetooth. I can look up a number in my Palm, tap it and it automatically dials on my phone. But unlike a smartphone, I can leave the PDA behind if I don't need it. If I want to sync my phone or pda with my computer, I don't have to find a cable, I just do it. If I want to check email on my laptop or my pda, I connect automatically through the bluetooth modem in my phone and it's like carrying a (admittidly slow until I get an EDGE phone) wifi hotspot with me everywhere. Driving in my car? Bluetooth headset. I don't even have to pull the phone out of the bag and there are no wires needed.
At the risk of sounding like a fanboy, Bluetooth is seriously cool. It makes it very easy for devices to interact. Will something better come along one day? Sure. But in the mean time, bluetooth does the job and does it very well.

Then when they're with you in your car, and you get an incoming call and your stereo automagically cuts off and a message pops up on the radio display with all your caller ID info, they're confused and a little shocked. Then when you hit a button and your talking via a mic in the car, and hearing the caller come in over the speakers, they're amazed.

That's pretty funny. Do you actually know about bluetooth? It's a very small, very cheap, very low-power radio technology for low-bandwidth data. It's not meant to be a 100ft-range-gigabit-ethernet-multimedia-streaming technology, but a useful replacement for low-bandwidth cabling. Headsets, keyboards, mice, microphones, etc. It does something other wireless chipsets don't, and nothing out there at the moment (or the forseeable future) can replace it.
Here's a nice scene: You're on your PDA, and not in a wireless hotspot. You want to check your mails, so you connect to your ISP using your phone which is in your pocket. You don't have to reach for anything - the two communicate, and you instantly have GPRS to your PDA. Or, another cool scene: At work, listening to music, and you want to check your voicemails quickly. Dial the answerphone on your phone (or from your computer), and listen to the messages over your headphones, nicely mixed with some quiet music from itunes or whatever, via bluetooth. Even better: send and receive text messages from your desktop/pda/notebook using a real keyboard. The list goes on.
People always pipe up and say something like "waah waah bluetooth waah crap waah WUSB is miles better waah waah", when they've blatantly misunderstood the purpose of the technology, and haven't realised just how useful it is.

Oops, hit submit too early... To finish my thoughts..
Zigbee (802.15.4) was designed for long battery life time and simple design. It achieves this long battery life goal with keep the receivers off most of the time. Depending upon configuration and the accuracy of you're timers, you're receiver might only be on a few milliseconds every couple of minutes. Not good for low latency or high bandwidth, but works wonders for making batteries last a year or more.
Bluetooth is about speed and QoS. Eats much more power than Zigbee, and only supports 7 devices in a Piconet. Zigbee is designed to support thousands of devices in a network.
Bluetooth and Zigbee are complementary technologies, not competitive. Even the IEEE says so (Bluetooth is on top of 802.15.1).

I use Bluetooth to transfer MP3 files to the phone which also serves as a MP3 player when I am not taking the car to work. I also got a Bluetooth car kit installed, hopefully I don't need to get a entire new set installed when I change phone in the future, just the holder/charger. You can even get cars with Bluetooh phone kits that fits with the car. On rare occations I have used Bluetooth and GPRS to connect to servers using SSH from my notebook, although the latency are REALLY bad, but if you are in the middle of nowhere it's better than having to drive home. Some of my co-workers likes to use those Bluetooth head sets.
I see bluetooth phones all over the place, from my desk at work, I see about 15 different bluetooth devices, phones, PCs, PDAs and printers. When I take the subway home from work I can always see 2-3 other Bluetooth phones.
I admit that a lot of phones had a lousy implentation with few features, which has not helped the adoption.

How do you select which device you are exchanging data with?
Interface depends on device, but normally you browse for them - a list is presented, and each device is named. Of course, you have to rely on the user having set the name to something more useful than "Nokia 3650" so you can identify which Nokia 3650...
Can you limit which devices can and cannot communicate with each other to prevent the nosy neighbors from listening in?
Yes, you can specify that devices need to a passkey to pair with each other. The neighbours don't get the key.
Can you limit which devices can and cannot communicate with each other to prevent the nosy neighbors from listening in?
Yes - you put your device in non-discoverable mode (similar to not broadcasting the SSID of a wireless network)
How do you enter a secret access password into a headset?
Or, indeed, a mouse as I had to set up for this machine. The answer is that the passkey is fixed on such devices, but they're also tied in with a hardware id (analogous to a MAC address). Thus another, similar headset with the same passkey still wouldn't successfully pair with your device - different hardware id

Most of your home automation ideas are already handled by Crestron. As far as all your CE deives self configuring by talking over bluetooth, that will never happen. The reality is that there is no reason for someone like Sony to want to communicate and integrate with Samsung or Motorolla, or anyone else. They would rather see a all Sony solution to the problem, therefore any automatic configuration solutions will always be proprietary. The only CE manufacturers that would be interested in something common are small manufacturers that can't offer a total solution. But then you have the overbearing licsening of Bluetooth.

Those predicting the death of bluetooth seem to usually be those of North American origin. In Europe, and ASia, where phoens are usually subsidised to hell, most "decent" phones being sold have bluetooth functionality. In terms of SonyEriccson, the SonyEricsson T610 is a phone which sold by the buckets, and is still being sold today, despite beign deprecated in favour of the T630, and the more advanced K700i. Other manufacturers are also incorporating the technology.
The reason behind popularity of Bluetooth is many fold:
- In Europe, Bluetooth headsets have REALLY taken off, especially thanks to the heavily enforeced bans on using handsets whilst driving.
- Bluetooth data communications are again increaingly popular (our GPRS systems are much more reliable, and its perfectly possible to conduct an internet session on a laptop, whilst screamign along in a 100mph train.. i know, coz i do that every evening). The phone stays in your pocket, and no messy wires to deal with
- for simple things just as transfering Ringtones, and gaming. People with SOnyEricsson phones easily swap rings and photos with others using BT technology. As well as wireless synch (try using Floats Mobiel Agent with a SonyEricsson phone via Bluetooth to simply blow your mind!)
These are just normal day to day applications of bluetooth. Tech people such as myself, use it even more.
IN my home, despite having a wires and Wireless networks, we also haev 2 USB BT dongles for the computers, a HP Bluetooth Printer, 3 Bluetooth Mobiles and a Headset. I use the headset for both the phone, AND as a wireless headset for VoIP applications on the computer.
In my experience, the technology has matured so well, it simply works. The only issues i have is on the PC side, where bluetooth stacks on the com0puter are either underfeatured, or clunky (dont get me started about MS's implementation in SP2). In all other bluetooth devices, the technology simply "works"
So to go with the parent post, i think the technology has matured enough to the point its possible to simply just make money out of it, there is very little extra that can be done. Why fix it if it aint broke?)

The CDMA providers/phone manufactures are just getting a clue about Bluetooth. In the US, Verizon should be selling a Bluetooth Motorola phone. Sprint has sold a Bluetooth Sony Ericsson phone (with lots of BT bugs), and Nokia has announced a CDMA flip-phone with bluetooth...
Doh!
Hope they got a shot of novacaine first.
Why would it? What other technology can do what bluetooth can do? It doesn't really have a direct competitor. The market is just not as large as some people expected. It does not "replace wires." It removes (some) wires for people who are willing to pay extra. Most of the bluetooth products are top notch and top dollar, so they have a specific market. Adoption was limited at the start.

Heh. It sounds as if you're American. Sony Ericsson has been doing major inroads the last year and a half or so, mostly at Nokia's expense. You see, while all of Nokia's phones look like an alien has designed them, Sony Ericsson's actually look nice, and they are almost all very feature packed.
Then again, you wouldn't know if you live in the US, since you lot have been 2-3 years behind in mobile telephony adoption for the last 10 years.
:wq!
In typical Slashdot function, we see people sitting here typing away responses about how useless bluetooth is for wireless-whatever due to its short range. Unfortunately for those people, they never realized that bluetooth is a wire-replacement technology. When I have my cell phone on at my desk, I don't want to feel like I am sitting in a hospital ICU bed with a bunch of wires hanging off my body. Instead, my bluetooth headset takes care of that part. Also, at my current location, internet access via Edge is far more useful and cheaper than buying DSL. So it serves two purposes right there that 802.11 is too killer for. Also, sync'ing my PDA is much easier than having to drag a craddle with me everywhere. My point is that SE is only moving their bluetooth operations under another division so bluetooth is not going anywhere and I am glad. 802.11 is too power hunger for the things I need to get done. Lastly, big manufacturers such as Dell are doing away with ALL legacy ports such are IrDA, Parallel, Serial, so we are left with firewire, USB, and bluetooth. Out of those, bluetooth makes the most sense.

Well, I clicked on "Reply to This" using my Bluetooth mouse connected to my PowerBook.
But it's arguable whether posting to Slashdot qualifies as "useful"
Insert simplistic political, ideological, or personal proselytization here.
The short range may have something to do with it.
If you think that's a liability, you really don't understand the hallmarks of bluetooth and what its purposes are.
Bluetooth has become commoditized; it's in the hands of low-cost chip manufacturers. That makes it uninteresting for a company like Ericsson and they are better off just buying whatever BT technology they need cheaper from elsewhere. If anything, that's probably a sign of maturity of the technology.
Perhaps if we're lucky, Bluetooth will go away.
You haven't used Bluetooth have you? Or maybe you just had a bad experience. I don't know. What I do know is that Bluetooth is a feature I now regard as indespensible in my phone, pda and, soon, headphones. I won't even consider a phone, pda or laptop without it now.
My phone and PDA (nokia 6310i and Palm Tungsten T3) essentially act as one device thanks almost entirely to bluetooth. I can look up a number in my Palm, tap it and it automatically dials on my phone. But unlike a smartphone, I can leave the PDA behind if I don't need it. If I want to sync my phone or pda with my computer, I don't have to find a cable, I just do it. If I want to check email on my laptop or my pda, I connect automatically through the bluetooth modem in my phone and it's like carrying a (admittidly slow until I get an EDGE phone) wifi hotspot with me everywhere. Driving in my car? Bluetooth headset. I don't even have to pull the phone out of the bag and there are no wires needed.
At the risk of sounding like a fanboy, Bluetooth is seriously cool. It makes it very easy for devices to interact. Will something better come along one day? Sure. But in the mean time, bluetooth does the job and does it very well.
Here's a nice scene: You're on your PDA, and not in a wireless hotspot. You want to check your mails, so you connect to your ISP using your phone which is in your pocket. You don't have to reach for anything - the two communicate, and you instantly have GPRS to your PDA. Or, another cool scene: At work, listening to music, and you want to check your voicemails quickly. Dial the answerphone on your phone (or from your computer), and listen to the messages over your headphones, nicely mixed with some quiet music from itunes or whatever, via bluetooth. Even better: send and receive text messages from your desktop/pda/notebook using a real keyboard. The list goes on.
People always pipe up and say something like "waah waah bluetooth waah crap waah WUSB is miles better waah waah", when they've blatantly misunderstood the purpose of the technology, and haven't realised just how useful it is.
Are you American? :)
Oops, hit submit too early... To finish my thoughts..
Zigbee (802.15.4) was designed for long battery life time and simple design. It achieves this long battery life goal with keep the receivers off most of the time. Depending upon configuration and the accuracy of you're timers, you're receiver might only be on a few milliseconds every couple of minutes. Not good for low latency or high bandwidth, but works wonders for making batteries last a year or more.
Bluetooth is about speed and QoS. Eats much more power than Zigbee, and only supports 7 devices in a Piconet. Zigbee is designed to support thousands of devices in a network.
Bluetooth and Zigbee are complementary technologies, not competitive. Even the IEEE says so (Bluetooth is on top of 802.15.1).
(An early 802.15.4 adopter)
So are people here a bunch of little old ladies?
All those people writing about it being dead. Are there no technology/gadet geeks here. I have many uses for Bluetooth.
I got a Notebook with bluetooth so I don't need any wires to update my calender. Updating phone numbers to friends, co-workers, business relations are a lot easier with Bluetooth.
I use Bluetooth to transfer MP3 files to the phone which also serves as a MP3 player when I am not taking the car to work.
I also got a Bluetooth car kit installed, hopefully I don't need to get a entire new set installed when I change phone in the future, just the holder/charger. You can even get cars with Bluetooh phone kits that fits with the car.
On rare occations I have used Bluetooth and GPRS to connect to servers using SSH from my notebook, although the latency are REALLY bad, but if you are in the middle of nowhere it's better than having to drive home.
Some of my co-workers likes to use those Bluetooth head sets.
I see bluetooth phones all over the place, from my desk at work, I see about 15 different bluetooth devices, phones, PCs, PDAs and printers. When I take the subway home from work I can always see 2-3 other Bluetooth phones.
I admit that a lot of phones had a lousy implentation with few features, which has not helped the adoption.
Ok, maybe it is just in my "world" that Bluetooth is used, or maybe it is just non-existent in America?
Yes, they are. Not certain of the standard though, so I don't know how difficult it is to brute force.
Interface depends on device, but normally you browse for them - a list is presented, and each device is named. Of course, you have to rely on the user having set the name to something more useful than "Nokia 3650" so you can identify which Nokia 3650...
Yes, you can specify that devices need to a passkey to pair with each other. The neighbours don't get the key.
Yes - you put your device in non-discoverable mode (similar to not broadcasting the SSID of a wireless network)
Or, indeed, a mouse as I had to set up for this machine. The answer is that the passkey is fixed on such devices, but they're also tied in with a hardware id (analogous to a MAC address). Thus another, similar headset with the same passkey still wouldn't successfully pair with your device - different hardware id
Hope this helps.

Most of your home automation ideas are already handled by Crestron.
As far as all your CE deives self configuring by talking over bluetooth, that will never happen.
The reality is that there is no reason for someone like Sony to want to communicate and integrate with Samsung or Motorolla, or anyone else. They would rather see a all Sony solution to the problem, therefore any automatic configuration solutions will always be proprietary.
The only CE manufacturers that would be interested in something common are small manufacturers that can't offer a total solution. But then you have the overbearing licsening of Bluetooth.
Won't happen.
Those predicting the death of bluetooth seem to usually be those of North American origin. In Europe, and ASia, where phoens are usually subsidised to hell, most "decent" phones being sold have bluetooth functionality. In terms of SonyEriccson, the SonyEricsson T610 is a phone which sold by the buckets, and is still being sold today, despite beign deprecated in favour of the T630, and the more advanced K700i. Other manufacturers are also incorporating the technology.
The reason behind popularity of Bluetooth is many fold:
- In Europe, Bluetooth headsets have REALLY taken off, especially thanks to the heavily enforeced bans on using handsets whilst driving.
- Bluetooth data communications are again increaingly popular (our GPRS systems are much more reliable, and its perfectly possible to conduct an internet session on a laptop, whilst screamign along in a 100mph train.. i know, coz i do that every evening). The phone stays in your pocket, and no messy wires to deal with
- for simple things just as transfering Ringtones, and gaming. People with SOnyEricsson phones easily swap rings and photos with others using BT technology. As well as wireless synch (try using Floats Mobiel Agent with a SonyEricsson phone via Bluetooth to simply blow your mind!)
These are just normal day to day applications of bluetooth. Tech people such as myself, use it even more.
IN my home, despite having a wires and Wireless networks, we also haev 2 USB BT dongles for the computers, a HP Bluetooth Printer, 3 Bluetooth Mobiles and a Headset. I use the headset for both the phone, AND as a wireless headset for VoIP applications on the computer.
In my experience, the technology has matured so well, it simply works. The only issues i have is on the PC side, where bluetooth stacks on the com0puter are either underfeatured, or clunky (dont get me started about MS's implementation in SP2). In all other bluetooth devices, the technology simply "works"
So to go with the parent post, i think the technology has matured enough to the point its possible to simply just make money out of it, there is very little extra that can be done. Why fix it if it aint broke?)
Have a nice day!
