Bluetooth v4.0 Dongle?

post #1 of 3
Thread Starter 
I'm on the market of buying a bluetooth 4.0 for a smell netbook i have, and i would like to know a couple of things first.

Does Version 4 come with EDR? Cause i remember versions 2.0/2.1 coming with it, eg You could see 2.0 + EDR when buying such dongle.

Does Low-Energy profile mean that the dongle consumes less energy or the devices connecting to it as well? Cause that would be pretty interesting to see.

There are version 4.0 BT adapters with EDR.

If the adapter and the devices support bluetooth low energy (BLE), both should consume slightly less power as they don't need to power their radios as often.

I've had good experiences with Cirago's adapters, but I have yet to personally use their BT 4.0 devices. This one does seem to have the features you are looking for, however:

The ones i look for dont seem to list EDR.

I read somewhere the BLE is only for specific hardware that brodcast in low energy frequencies (like medical equipment) which i dont care about. Mostly my concern is that i have the PS3 Bluetooth Remote Control, and i use it on the PC with 3rd party drivers. I?t seems that when connected on the PC the batteries are drained almost immediately, (1 week max) while when on the PS3 it can last for months. So i'm wondering if Bluetooth 4 will solve this somehow.

Bluetooth 4.x -> Introduces support for collecting data from devices which generate data at a very low rate. The main intent of this feature, called Low Energy (LE), is to aggregate data from various sensors, like heart rate monitors, thermometers etc.

The 2 Dongles i now have in mind, in case you've heard any of them, is Belkin F8T065bf (Class 2) and LogiLink BT0015 (Class 1), Belkin is a more established name, but the other one is cheaper and its class 1 as well, which is better. Both are v4 but i dont see anywhere if it supports EDR.
