nRF52 support ISO7816 protocol

Hi,

let me know if nRF52 support ISO7816 protocol for Smart Card Interface.

  • Hi,

    Do you have any reference design with ISO7816 protocol/interface?

    if so, can you kindly share the design?

  • Hi Jiacheng,

    Thanks for the additional information.

    In our case, we are talking to a custom part and the UART interface to the card/part does not require the high current supply--so that part isn't an issue for us. But we do need to talk using 7816 protocol. I'm not certain yet whether we would try to interleave it with BLE using time slots, or whether we may be able to make the two mutually exclusive (e.g., disable the radio for the situations where we need to use 7816 protocol).

    From what you've said, it sounds like the 7816 library you are using does not have built-in support for arbitrating with the radio using time slots--that the application level has to take care of managing the time slots and be sure to only use the 7816 library at the allowable times? Or does the library provide time slot management too?

    Finally, is there any plan to make the library available?
