802.11 Data Transmission

For the every ten seconds application, you could do a kluge along the lines of having the Model Aircraft send out 802.11 beacons with the desired data embedded somehow in the SSID field. Then some application-layer program could look at the SSID's of available networks, and extract the data. No association, no protocol layer, no digging into the handset's 802.11 implementation. Not a reliable protocol but you don't have to maintain a connection -- just simplex data transmission.

Your second application requires more effort, and such a kluge is not sufficient.

What sort of processing power do you have on the aircraft? You could certainly implement a TCP/IP stack (there are open-source ones available, like uIP and lwIP) on the aircraft's processor, then actually create a TCP or UDP connection to the iPhone to transfer the data. There is an SDK available for the iPhone, but I think it is only available for OS X.

There's somebody here who knows how to spell kluge!!

Hooray!!!!! ;-)

Yes I was downloading it only to find that it works on apples only. There is a fix of sorts that emulates an apple-mac hardware then you can install os x but it sounds a mission. The sdk is free and has lots of examples. I don't want to have to buy an apple-mac, so I may have to do this for a pda instead.

It is actually not that difficult to assemble an UDP packet, and send some data. The bad side of UDP is that there is no guaranteed delivery.

The hardware is very simple, build that circuit some years ago, a small FPGA will do.

There's a right way?

I've seen, over probably thirty years time:

kluj - sometimes with an umlaut, which gives it a little class. kludge kluge klooj

And probably several others.

Is there some formal etymology that favors one over any other?

Fascinating, I read these two references and see definitions that are sufficiently close to each other that they are not, to me, two separate jargon-words with different meanings.

Anyway, I prefer the spelling kluge because it is more phonetic for how the word is pronounced. Whereas kludge would rhyme with fudge. Others may feel differently.

PDA would have been my first choice.

You can use uIP protocol stack on flying device:

OK, this one is spelled the way I don't like, but according to the pronounciation key, it's pronounced right. This sets up a dissonance in my brain, because to me, the 'd' makes it rhyme with "fudge".

This isn't a bug in my brain, it's a feature. ;-D

But at least everybody seems to know how to pronounce it! Whew! ;-)

Cheers! Rich

Oddly, this seems to make a lot of sense to me - one must admit, doing a proper kluge does entail a bit of cleverness. ;-)

Actually, both would work better as bluetooth.
