Re: [android-developers] Re: NFC Secure Element

Hi Michael,

As far as I understand sending APDUs to the SmartMX SE element is possible because the NFC Controller (PN544) is told to enable the NFC-WI interface with SE. This is carried out by calling phHal4Nfc_Switch_SMX_Mode(), with parameter eSmartMx_Wired (function phLibNfc_SE_SetMode()).

Wouldn't it be possible to use the SWP channel to send APDUs to UICC SE through NFC Controller in an "wired mode" from an application the same way it is performed when sending APDUs to the SmartMX element? Or is SWP only supposed for raw RF Communication and has no such equivalent capabilities used by NFC-WI?

Taking a look at the libnfc-nxp library theare are some SWP related functions that are not being used.Maybe phHal4Nfc_Switch_Swp_Mode() could be used in a similar fashion to phHal4Nfc_Switch_SMX_Mode()?
