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()*?
