Junko, I also get frustrated with marketing speak that I don't understand. In my brief investigation of this Bluetooth Smart, I see mainly three changes:

1. Low power, of course. They do this by not requiring a constant transmission, but rather pulsed.

2. Also low data rate. Apparently, usually no more than 64 Kb/s, and sometimes only bits per day.

3. A single profile. This is very important. In Bluetooth Classic, so-called, any new device that wanted to be connectable via Bluetooth had to have its profile entered into the spec. So that when the device comes online, Bluetooth will recognize it and know what comms it is expecting. If this can always be consistent, you're better off. New devices can be connected immediately.

I'm not sure how #3 will keep from becoming a restriction, eventually, unless what this really means is that the profiles are handled always at the application layer.

I should add, by my understanding of what constitutes "smart" devices, this actually make Bluetooth Smart dumber than the Classic. It's slower and it knows less about the connected devices, than Bluetooth Classic.

"In my mind, Bluetooth Low Energy conveys much more clarity. It describes what the thing actually does." I couldn't agree more. In fact, when I first heard of the name change, I felt it conveyed the opposite message, because the most common "smart" device we all use daily -- our phones -- have terrible battery life. Smart implies processing power, not long battery life. I don't want my BT devices to be smart, I want them to be low energy!

I know, betajet. The first time when I heard people saying "BLE," it took me a while to figure out what they were talking about. But now I get a hang of it, I'd rather like it. Then, I was advised that it is no longerteither BLE or Bluetooth Low Energy, but Blutooth Smart. Ugh.

@Junko: Bluetooth Low Energy (BLE) is now Bluetooth Smart...

If "Bluetooth Low Energy" = BLE, then what does "Bluetooth Smart" = ?

@betajet: "How can anyone believe that by the 25th Century they haven't developed a cure for baldness?"

Having just returned from the 25th century myself, you will be happy to hear that they certainly have invented a cure for baldness (I could live without the ladies sporting handlebar moustaches) -- so we can only assume that Captain Jean-Luc Picard was making a fashion statement.

I pronounce DAC as "D. A. Conference".  "Dack" is a Digital-to-Analog Converter, or maybe Data Acknowledge.

Regarding how to say TNG, I have no opinion.  For me, there is only one Star Trek, the one I first watched on a small B&W TV.  A friend of mine once said he found the whole concept of TNG to be preposterous.  "How can anyone believe that by the 25th Century they haven't developed a cure for baldness?"

Changing the name to Bluetooth Smart sounds like a lot of BS to me.  Not a good idea IMO.


I rather like BLE.  I once wrote a logic editor called BLE.  It's also fun to go around saying "blee blee blee".  People think you've lost it, but it is fun.

@ Junko I am so weary of the world of smart everything.

We could use the word 'intelligent' instead, except for:


a) Marketeers loathe words of more than 3 syllables, too hard for consumers to remember, so 'intelligent' would have to be shortened to 'i'.


b) Apple might then claim trademark rights to the letter 'i'.

@Junko: But seriously, how do you pronounce TNG as an abbreviation?

You spell it out like "Star Trek T-N-G"

Like the design automation conference where you can spell it out like "D-A-C" -- but unlike it in that you can't say TNG as one word, but you can say "DAC" to rhyme with "snack"
