Hi

Apologies, I seem to have not been notified of replies to this thread even though I checked the box.

I'm not sure if you contacted them yet Massimo (which is very much appreciated) but they finally contacted me yesterday and claimed to have now received my returned shield.  At this stage I've now asked them for a refund as the whole affair has been going on for over a month.  In the last week I've ordered the shield from a company in the uk, Robosavvy.  Shield was delivered in two days in perfect condition.  Hopefully I'll see my money back from Alpha Crucis soon.

thanks again

Hi

Trying to get a WiFly (this one http://www.sparkfun.com/products/11047), xBee Pro Shield and Arduino Duemilanove to work together.  Ultimately I want the arduino to pull data from the web but at the moment getting anything working and understanding it would be a start.  I've started with the WiFly_Test sketch, entered my network details, uploaded it and watched the serial monitor but it gets no further than "Starting WiFly Tester. Free memory:1168".  The red leds never stop flashing (im guessing a bad thing). 

Can anyone recommend a tutorial that walks through the WiFly_Test sketch step by step or another very simple one?  All the tutorials I'm finding are broken links.  Or can you tell me if something needs to be done before I upload the sketch i.e. does the WiFly need to be pre-configured?  What about the xBee/USB switch on the shield do I need to toggle that between positions?  It seems you do if you have an xBee on the shield.

Thanks in advance.

Hi

Not expecting that anyone here can or could do anything about this but since I live in another country to the seller it seems I can do nothing.  EU law states that customers from other countries have rights but when things go wrong there seems to be no course of action, no body that deals with it.  If I have bought this through amazon or ebay there is a clear process to follow but on the sellers site I can't even leave feedback.  Hopefully people will see their name here, avoid them and not have the issues I've had.

For those who live in Europe and are buying Arduino related materials, here is a seller in France to avoid at all cost.  It's difficult enough starting to use Arduino with the price of materials without buying from a seller who is dishonest.

I bought an xbee shield for Arduino from Alpha Crucis (https://www.alpha-crucis.com/).  It was delivered to me in Wales without a receipt and broken in the box (see the doubled over header in the attached image).  I asked for a replacement as I didn't trust myself to bend the header back into place being new to electronics, was obliged to pay the return postage and have never seen a replacement.  I complained several times to the seller who doesn't reply.  There are other sellers around in Europe so I's suggest you avoid this one.

Yes you are correct, you just need the shield and the WiFly RN-XV. Resistor voltage dividers for 5V to 3.3V are fine. The diode solution on the sparkfun XBee shield is an example of a broken solution that does not work.

Sorry panicky I bought the wrong one.

The shield you ordered looks like the same one from DFRobot. I have one and it works, although it reboots the arduino whenever the WiFly reboots, and I cut off pins 0 and 1 and soldered a couple of jumper wires to them so I could connect them to other pins (8 and 9) to use software serial.

Same code so I hope so.  Thanks for reassurance.

when choosing, always go with the most popular/widely used. And that appears to be wifly.

Good to know, I was worried about examples and finding support if this was complex.

For the adapter, make sure you get one with actual level converter (5v to 3.3v) chip, like this
https://www.adafruit.com/products/126

What's the adaptor for?  I thought it was: Duemilanove -> xBee Shield -> WiFly
Is there something else that needs to be in there?

Thanks for your advice, I've found both WiFly and Xbee shield.

WiFly: http://proto-pic.co.uk/rn-xv-wifly-module-sma-connector/
xbee shield: http://www.alpha-crucis.com/en/shields/72-xbee-shield-for-arduino-3700386600159.html

Seems much cheaper than some of the original solutions I had seen so I'm going to order these tomorrow.

Hi

Ok so it's got an external antenna and I've found a uk based supplier but this isn't plug and play is it?  I need a shield, what do I need to connect it to a Duemilanove?

>All of the WiFly modules support WEP, WPA, and WPA2, including the more

Is this a comment about the note I had on unprotected networks?  I saw that on a forum - is it not true?

Thanks.

Hi

New to Arduino, I'm working on an idea that will allow control of the arduino from an online webpage.  So if I understand correctly something like:

html/Javascript -> PHP -> Arduino Duemilanove

I know the first two steps (html/Javascript and PHP) and the Arduino side is reasonably simple however I need the arduino to be able to connect to the internet wirelessly and this seems quite confusing due to the number of shields and their differences.  So far I've come up with:

Xbee wifi: http://www.digi.com/products/wireless-wired-embedded-solutions/zigbee-rf-modules/point-multipoint-rfmodules/xbee-wi-fi#overview

Arduino wi-fi shield: http://asynclabs.com/wiki/index.php?title=WiShield_1.0
http://asynclabs.com/store?page=shop.product_details&flypage=flypage.tpl&product_id=29&category_id=6

Anaconda Wi-Fi Shield for Arduino: http://www.robotshop.com/eu/productinfo.aspx?pc=RB-Lin-31&lang=en-US

Copperhead Wi-Fi Shield for Arduino:
http://www.robotshop.com/eu/productinfo.aspx?pc=RB-Lin-39&lang=en-US

DFRobot Wi-Fi Shield for Arduino: http://www.robotshop.com/eu/productinfo.aspx?pc=RB-Dfr-132&lang=en-US

Arduino WiFly Shield (unprotected networks only so not a good option): http://www.coolcomponents.co.uk/catalog/arduino-wifly-shield-p-456.html

and finally an Ethernet shield connected to a linksys gaming adapter (but I believe this was a pre-Wi-Fi shield solution from the old forum).

and I'm finding more and more.  Can somebody advise which is appropriate for what I'm trying to do, is plug and play, ideally has a external aerial and is available from a supplier in the UK (or Europe)?

Thanks in advance
Garrett
