HCE example8 not working on PNEV5180 evolution board

[marcinbaliniak]

Hi,

I'm trying to run NfcrdlibEx8_HCE_T4T. It is working fine on my custom board ESP32 + PN5180 - fine but with limited range for my Android device (Xiaomi Mi Mix 2) and really limited range for iPhone 9. I think this can be because of the antenna tuning so I tried to run the same example on dev kit with ESP32 connected over SPI - so basically the same software but on your dev kit. I don't know why but in this case it is not working at all on Android and iOS. The PN dev kit + ESP32 setup is working fine because I can use it with any other examples and it detects tags etc.

So my question is - do I need to make any modification to the dev kit to make it work on HCE mode?

BR,

Marcin.

Hi Marcin,

How did you manage to port NFC lib to ESP32.

Did you find a porting guide or sth similar?

I am going nuts trying to port. Any clue will be welcome.

Regards, Ramon.

Hi,

The problem was that most of the examples were working except the HCE. But thank your suggestion I found I didn't remove two resistors R233 and R235. Not HCE mode is working on dev kit also.

btw. Application not is AN11908

Thanks

Marcin.

Hi @marcinbaliniak ,

Yes, the link should be https://www.nxp.com.cn/docs/en/application-note/AN11908.pdf . Sorry for the confusion that has caused.

Have a great day,
Kan

Hello @marcinbaliniak ,

Since your custom board ESP32 + PN5180 can run the example of NfcrdlibEx8_HCE_T4T well, the porting should be great! so it is most possible to be a connection issue, please refer to https://www.nxp.com.cn/docs/en/application-note/AN11744.pdf especially the section of "5.2 Connecting the FRDM-K82F to the PNEV5180B" , it is for the board of FRDM-K82F, but the connection should be the same for your ESP32.

Hope that helps,

Have a great day,
Kan
