If you mean Bluetooth 4.0, its bandwidth is like 50kbps IIRC. It can't be used for anything other than heartbeat monitors and stuff like that. I know absolutel

I know absolutely nothing about Bluetooth, but I watched a WWDC 2012 video about it just for fun. It was an extremely well-done introduction to this technology.
Session 703, Core Bluetooth 101 - https://developer.apple.com/videos/wwdc/2012/ https://developer.apple.com/videos/wwdc/2012/ (requires a free developer account)
- sp332 14y agoBluetooth runs at ~2 Mbps which is not too shabby. And there's a new (as of BT 3.0) "high-speed" mode which actually sends bluetooth traffic over 802.11, so you can keep your wifi radio off until you actually need to send a lot of data. edit: I haven't watched your video yet, but thanks for the link :)
- pooriaazimi 14y agoSorry, I thought you were talking about Bluetooth 4.0, which is very low-power and very slow. These two slides are from the aforementioned talk. Note that 'Classic' means 3.0 and 'Low power' means 4.0: http://d.pr/i/cRvm http://d.pr/i/cRvm http://d.pr/i/qCHB http://d.pr/i/qCHB
- sp332 14y agoWell 4.0 includes "classic" and the new low-power mode. But I see on Wikipedia that BT has a 3 Mbps mode (aside from the 802.11 "high-speed" mode), do you know what that would refer to?
