2.4 ghz WiFi ID

[Darrel Taylor]

Could you clarify what "broadcast an ID every so often?" means.

Modules that can do an "Ad-hock" connection will broadcast it's SSID.
But I'm not sure if that's what you want.

yes, that would be fine. It would be nice if all I had to do was power up the module and the SSID would broadcast but I would have to time it out so my battery would not be exhausted prematurely. Thanks Darrel

I was just on mouser's web site thinking of order one Darrel after you mentioned adhoc, I've gotten pretty comfortable using the 16f628a in my projects and am looking at the 18f's to experiment with when I purchased the module mentioned earlier from Microchip the data sheet mentioned the 18F's prior to the TCP/IP V6 and thereafter 24F's? and higher. The '628 has really been fantastic for me to learn with any suggestions for the 18f's? I am curious about how to connect to ethernet but before I ask anymore questions on that I want to do a little more research.

Thanks again Mackrackit, Darrel and Normnet for your help.

"adhoc", I knew I should have looked up the spelling.

I thought I saw something about a Rabbit Hunt ... I think they would be perfect.
One module can connect to other modules, and it returns signal levels for each device it finds.
Zeroing in on something wouldn't be too hard at all.

They are not a Web Server. They don't serve up webpages. (Although your program can).
But you can connect to other things on the net.
Synchronizing time is automatic, so it's great for clocks.

I think the best part is that two modules can connect to each other without the need for a wireless router (adhoc).
I haven't seen a better way to connect two PICs wirelessly. 802.11/G, can't get much faster than that.
Of course you are limited to 1 megabaud from the USART, and it's not secure in adhoc mode.

The 16F628 will work fine with it.
A 12F1822 (8-PIN) will work just as well.

@ 4uA sleep current, it can keep your batteries in good shape.

Sorry for what sounds like a commercial, but I've been having fun with the RN-171.
And I guess Microchip knew a good thing when they saw it, and bought them. I didn't know that.

Hi Tazntex,
If you like the 628a, you will love the 16F648A, same chip same data sheet twice the memory for about 30 cents more.

Not too much information about these. Can anyone tell me if the RN-171 can connect to a smart phone via wifi? I'm guessing that would be ah-hoc mode?
