Trying to test SnepDemo or LlcpDemo with Nexus 7

[Mario Machado]

Hello!

I got an ACR122U reader last week and I'm starting to take a look at nfctools (still kinda lost). 

I was trying to run the SnepDemo (eclipse, on a Mac), using a Nexus 7 (Android 4.2.2), without luck... I also tried to run LlcpDemo or LlcpService, same thing...

Thanks in advance,

 I also tried using target mode (both passing the parameter or setting the variable in the code), but then I get this even before tapping the Nexus:

Hi Mario,

I assume you have the ACR122U-A9 model. Unfortunately this model behaves a little bit different than the model I own (ACR122U-A2)

Since I don't have access to the A9 model it is difficult to find out what differences there are.

Regards,

Adrian.

Hey Adrian,

Thanks for the response. Yeah, I checked the version, the model is A9 as you said...
