Hi,

I used arduino v 0.22 to upload the arduino code for RFID from your page, but it never reads the card. The jumpers are at the XBEE side and the 125khz gets permanent in green light. The message I get is Waiting card, Waiting card, Waiting card...

What can I do?

Cheers!
Dani

Hello Dani

Thanks for your question.


What kind of cards are you using? Are you sure that the cards that you are using are compatible?

I don't know if you have seen the tutorial that we are prepare for this module

(http://www.cooking-hacks.com/index.php/ ... duino-rfid) ?

On the last part of the article you have a video tutorial that could clarify you the process to use this device.

Regards and best wishes.

Hi!

Yes, I followed that tutorial without result. I bought the RFID Tag Combo. I tried all of them in all positions and nothing...

Hello dandonsol

Could you send me the code that you are using to test the RFID module?

Send me a photo of how you are connecting the RFID module please.


Thanks for your time.

Hi!

I followed the video step by step. Here are the images of it.

Hello dandonsol

Thanks for your answer. We have been reviewing the combo kit with the module and the code and it works properly.


Could you send us a photo of the antenna? It has some small wires that could be broken.

Could you check if the connector of the antenna fits properly with the module, please?


Regards and best wishes

Hi,

The connector fits well and I tried upside down too.

Here some photos of the antena. I couldn't see anything broken.

Any idea?

Hello dandonsol

Could you check if the green wire connects to the antenna, and no one of these wires are cut?


If you don't see any problem with this, please go to this page :

http://www.libelium.com/support/technicalservice

And fill the invoice. With this we will proceed to repair-replace the broken hardware.
Please refer to the link of this threat.
