PN7150 nfcDemoApp poll Crash

[ethan_dang1]

I use Raspberry 3B & OM5579/PN7150RPI run the demo "nfcDemoApp poll " follow Easy set-up of NFC on Raspberry Pi - NXP Community

Usually works normally，But when I put 2 MIFARE Classic cards into the field at the same time many times in a row, it crashed.

(

it’s ok when put 2 NTAG213 cards into the field at the same time many times in a row;

it’s ok when put only one MIFARE Classic card into the field at the same time many times in a row;

)

Why? There are logs here, please help analyze them ,Thanks!

Hello @ethan_dang1 

Thanks for sharing and contacting us. Based on your description I'd like to know why do you put two mifare classic cards on the field at the same and does your application scenario have to be like this? I want to know this because I need to make sure if the Demo supports this application scenario.

Hi Kelly @KaiLi 

Put two mifare classic cards on the field at the same because it happens sometimes(.e.g Multiple cards in the wallet,just put wallet directly into the field)
