Card Emulation Mode Supuport

[solosky]

Is your feature request/improvement related to a problem? Please describe.

Yes, the CE mode for ST25R3916 is missing.
Checked the code, and listen like feature is returned NO_SUP.

Describe the solution you'd like

I see the CE mode function is there but it's not implemented and always returns NO_SUP, it seems removed by purpose.
I know this feature is missing currently, but I would like to know is there any limitation (hardware or firmware) to implement CE mode via Aruduino Framework?

Describe alternatives you've considered

The RFAL supports CE mode.

Hello @solosky ,
checking the hardware specification, it seems that the card emulation is supported from the hardware, so I don't see any particular limitation from hardware point of view. Probably, when we developed this library some years ago the card emulation feature was not supported by the RFAL software version that we ported in Arduino and I suppose that this is the reason why it returns NO_SUP. Unfortunately, I do not have band to work on it, so any contribution by the community is welcome to improve the library adding the Card Emulation feature.
Best Regards,
Carlo
