Infrared or Bluetooth?
Since am old school, I find that most of hardware manufacturers use irDA implementations for devices like remote controls. And these devices work very well. On Phone handsets I can agree that irDA will not work due to line of sight issues and therefore BT is much better suited. But BT is just a very small sector compared to irDA. However, I'd invite @James Nzomo to write more about BlueTooth and whether it at all is catching up to the irDA market devices, why manufacturers still prefer irDA and what extra processes are needed to sustain a BT service. Rgds.
Lets begin with this -> *"*But BT is just a very small sector compared to irDA."* *really? You seriously claim that the same BT that caters for nearly every aspect of digital data exchange *"is a very small sector"* compared to a fading technology that hopelessly clings on by allowing you to send one way commands from a "DUMB" device? I see no need to point out the benefits of BT of you haven't already seen them I will leave that task up to Google and the rest of the internets. But here is a related though fictional story: There is an episode of TNG where the crew of the enterprise D discovers Scotty trapped in a stranded ship's transporter mechanism. Further down the episode, Scotty is amazed at the Enterprise D tech advances especially in the engineering section. When issues arise, he tries to insist that *his old school concepts and knowledge will work better* but they prove to be a bother and an irritant to the modern Eng. Crew. Finally La Forge tells it to him and the old fella makes his way to the holodeck where he asks LCARS to recreate the original NCC-1701-A USS Enterprise A Bridge. At last! He finds tranquility.

@James, Hahaha...That is really funny re: the short story of Old engineer/new engineer. :-))) FYI : Infrared is used in almost every hardware device found in the consumer electronics sector. From remote controls to sensing movements to security systems to thermal iamging/sensing too. But you wrote on another thread that this technology is really out dated and old school and you believe Bluetooth is the way forward. Infact you are developing on bluetooth stack. So go on, don't correct my postings, just do your thing and enlighten the tech list further. I'm keen to know besides phone handsets, a few gps devices and possibly only MAC that use bluetooth for keyboard/mouse functions, what other applications is Bluetooth into? And please try and avoid referring me to google, it gets really boring. Its nice to be able to engage in discussion with fellow technologists. Rgds.
*"FYI : Infrared is used in almost every hardware device found in the consumer electronics sector. From remote controls to sensing movements to security systems to thermal iamging/sensing too."* There is a difference between *IrDA* and the applications i have highlighted in bold red that you quoted. I remember talking about *IrDA<http://en.wikipedia.org/wiki/Infrared_Data_Association> * and not *infrared <http://en.wikipedia.org/wiki/Infrared>*. It is very difficult to enjoy a discussion with all this skewed (and incorrect) info being posted. That's why i see little benefit in discussing any further. BUT..here is the deal. How well do you know IrDA? If you describe it in detail plus *ITS CURRENT & PREVIOUS USES (WITHOUT SKEWED OR INCORRECT INFO)*then i will be obliged to do the same for BLUE TOOTH. PS. kindly do not extrapolate. Describe it for what it *really* is. _______________________________________________ *Good judgement comes from Experience.* *Most of that comes from Bad Judgement.* _______________________________________________ * * 2011/12/6 aki <aki275@gmail.com>

I don't develop on irDA or BT so have never had any need to go into depth details. Period. I wanted you to share some of your thoughts since you develop on it. My reason for moving from irDA to infrared spectrum is the scope that covers the infrared range, which covers the infrared diode unlike the wireless set frequency limitations of bluetooth. Lets focus on the use in the very popular remote control systems in consumer electronics as this was that got my interest going from an earlier thread. Why is it that most manufacturers still use this old school system and not bluetooth? I think the irDA technology is very reliable, does not suffer from interferences, and is quite simple to implement. Each light pulse is decoded on the receive side as a particular signal pattern that corresponds to what the decoder processor is programmed to respond to and is a direct tranlsation of light pulses into signal levels. Due to its simplicity and reliability, it will be favoured over other technologies like BT or Wireless. The only disadvantage has been the line of sight but I think this is no longer due to better diodes with a broader focal and light emitting range. These are my basic thots so far. I sometimes notice the rudeness of people on this list when I post things, I've so far not reverted and kept track of the discussion. I hope to maintain this. Over to you, go ahead and share since you are quite deep in BT research as you develop on it and will know much more than many of us. Rgds.
