She'll be really sick once this is done:

They're replacing every phone booth In NYC with WiFi access points.

They still have phone booths? I don't think I've seen one of them in years. There was a trend for little stores to have an unofficial pay phone somewhere, but those are gone too. Obamaphones.

If we ever get pervasive public wifi or equivalent, which makes sense, the phone companies are dead. And the cable companies, too.

If anything, Wi-Fi is over-developed.

There are plenty of development kits and boards available: Every manufactory of wireless chips has them for reasonable (not cheap) prices. However, there's a problem. You may need to sign an NDA (non-disclosure agreement) to see the chip data sheets and obtain linkable libraries for building drivers.

Access to tech support depends on what level of support you're expecting. If you need basic design help, be prepared pay. If you're fighting what might be a bug in the chip or development system, maybe they'll listen, promise to return your call, and then do nothing. If you need applications support, where you're designing their chip into the next big thing, support will do whatever you ask in order to get a high volume design win. If you're a student, hobbyist, or enthusiast, you'll do better on the company forums getting support from other users.

Perhaps it might be useful if you would disclose what you're trying to accomplish, what you have to work with, your ability level, and some clue as to how many dollars you consider to be cheap.

Good luck.

The ESP8266 wifi modules are less than $5, it can be programmed with the arduino IDE

dataheets, SDK, etc.

That was a very condescending and racist remark.

That was a very condescending and racist remark made by John Larkin and JW. They should be kicked out of this group for good.

If people could be kicked from this group for bad behavior there wouldn't be anyone left.

Good plan. The ESP8266 is probably a better idea if he's starting from zero.

However, that's not what I assumed that the OP was doing based on his minimal information. My guess(tm) was that he was starting with one of the current Wi-Fi chips, and designing a product from essentially scratch. The ESP8266 is a SOC (system on chip) with a built TCP/IP stack eventually delivering SPI/SDIO or I2C/UART serial I/O to an Arduino board. That insulates the designer from much of the politics and headaches involved in directly interfacing to a Wi-Fi chip.

I thought it might be interesting to read through the datasheet and see what they're doing for the RF section. I didn't find much: I can't seem to find anything that looks like a real datasheet. Plenty on interface specifications and general specs, but little detail on what goes on inside. This is the best I could find: which eventually led me to this: Looks like they have a development board for using the chip. See Pg

24 in above PDF.

Since you failed to quote a goddamned thing... WHAT was? The term "Obamaphone"?

It qualifies as neither, idiot. Go back to school.

THIS is NOT a "forum", dumbfuck. It is a USENET NEWS GROUP.

Get off your f***ed in the head web browser, AFTER you look up USENET, and READ UP on it.

Come back when you have half a clue.

Ok, you son of a bitch ! its a usenet not a forum.

Ok, I will vote John Larkin off the island.

And that idea will work, just /how/ well? :-)

(To the original poster: a bit of research should make it clear to you that there is really *no* way to "kick a person out" of a USENET newsgroup such as this, short of illegal sorts of violence that would get the perpetrator thrown in prison for an extended stay. Can't be done. Newsgroups such as this operate on a highly decentralized set of servers run by many different companies, schools, and individuals. They have no "central authority" with the power to ban an individual; there's no single individual or organization to which you can appeal or argue your case.

The nearest thing, I think, is a simple "kill-file". Program your newsreader to ignore any posting by the person you dislike, or any posting which quotes him/her, or any message thread in which the person participates... whatever level of filtering you prefer. In other words, shun him/her, if his/her on-line behavior does not suit your personal sense of morality, ethics, or decorum.

That technique works both ways, of course.)

...and self-involved that she may have difficulty on Usenet anyway. It does tend to be hard on people who dish it out but can't take it.

Passive-aggressive attempts at controlling people through baseless acccusations only work where there's an HR department, HOA, or other kangaroo court involved.

And, 'jess', y'know, it's pretty unpersuasive, calling other people cowards when your first recourse is to try taking away their friends and you don't sign your real full name?

More to the OP:

On the plus side, on Usenet you get lots of chances. Just pick a new nym and try being civil next time. Nobody will know who you are unless you want them to.

It's easy to build good will round here-- helping others, being funny, and/or just asking good questions will do it in a day or two. But this sort of stuff, especially from someone who isn't a regular, will lead nowhere.

Hi Jess,

If you have never worked with Wi-Fi before, perhaps you could have a look at the Arduino WiFi Shield

or, as others have suggested, a serial-to-WiFi module as the ESP8266. Both fit into your description of cheap, with technical support and easy to use.

If you can provide some additional info on your background and the intended application you may get some useful (really!) help from this newsgroup, perhaps even without changing your nym.
