Hi,

I purchase those two products…

I connect the brick to an arduino uno and I extend the antennas cable at 5m. Then I run the example sketch from the wiki page.

Rx/Tx are connected to 5 and 6 pins so I change two lines of code from this

attachInterrupt(0, ISRreceiveData0, FALLING ); //data0/rx is connected to pin 2, which results in INT 0 attachInterrupt(1, ISRreceiveData1, FALLING ); //data1/tx is connected to pin 3, which results in INT 1
to this

attachInterrupt(3, ISRreceiveData0, FALLING ); //data0/rx is connected to pin 2, which results in INT 0 attachInterrupt(4, ISRreceiveData1, FALLING ); //data1/tx is connected to pin 3, which results in INT 1
But when I approach a card or a token to the antenna I got nothing on the serial monitor.

I know that the wiring is correct because the green led on brick blinks when a card is near.

Any ideas?

Thanks

It worked by set the jumper to W mode
