Has this been done already? I am just starting to look into how a Prop could be connected over wifi and available for remote access/control via the net. Several concepts come to mind: Remote diagnostics and testing, setup. Remote program updates.

I did it with Wifly GSX... Very easy to use.

T Chap,
I have 2 separate propellers running a wired 10baseT WIZNet W5100 to (ok a separate wifi router). Everything is working well so far on the Parallax Spinneret with the evolving community code stack. One of my AJAX clients has refreshed 450,000 times over the last 24 hours on one of the embedded servers. The two propellers don't talk together over CAT5-802.11n-CAT5 but they will hopefully soon.

Thanks for that info guys. To get the general concept of using Wifi, is this close?

1. Prop uses two pins, Tx and Rx to transfer data over the WiFly GSX which is connected to a wireless router.

2. The GSX will automatically scan for nearby routers, and will report what it finds in ascii format back to the Prop, then the Prop must choose a connection per boot or must have a selection already stored in memory. If required a password can be entered manually or can be stored in memory.

3. A user at some remote location accesses the net via a website(html etc) or a GUI that is connected to the net. Data is sent and received by the application or web browser at some rate.


Does the system require a static IP? If dynamic IP is used, is the the job of the Prop/GSX to log onto the remote site? In that case, the remote would have to be static right?

So if I am correct, in some ways the Wifi acts just like an Xbee in some ways, just a wireless method of transferring info.

The Wifly GSX has a few different modes of operation. But what you've discribed is about how I used it.

I told mine to autoconnect to my router on boot up. It gets it's IP automatically from the router...

Thanks Rayman, I spoke to their tech support today, very helpful and nice group of people. I ordered the 134 to test out. Looking forward to the learning experience.

The question still remains unclear even after talking to the tech about how to do real time remote GUI access.

I will get the WiFly GSX in on Friday. Can anyone suggest where to start studying up on a TCP/IP stack for the Prop? I see a lot of threads on this but am not sure where to begin.
