Ok, there is a chip between the SIM and the reader.. So, my reader communicates with the COPNI's chip, not the sim..Yes, your ACR122U reader communicates with COPNI's NFC chip only, not the SIM card.
If I find the "BLADOX Waver", will I be able to select the applet in the sim? or not? or what's the solution to select the sim applet via NFC reader (with a RF Add On)?Please keep in mind that microcontroller in BLADOX Waver has its own firmware. And this microcontroller is a main device communicating with a mobile terminal (phone), SIM card and a NFC chip. IMHO if you want to select the SIM applet via NFC reader you should to develope the appropriate applets for SIM card and NFC chip. Also you should to develope appropriate firmware program for microcontroller.
Also you should to develope appropriate firmware program for microcontroller.For what exactly?
Isn't the CL ATR generated by the reader since T=CL doesn't have an ATR?Not only. The NXP SmartMX chips have a feature of configurable ATR at a pre-personalization stage.
For what exactly?That firmware program for microcontroller will execute a function of the supervisor. One way is that a supervisor program inquires the NFC chip periodically by selecting and sending the appropriate APDUs to the gateway applet. If a gateway applet at NFC chip has a request for SIM card applet then a supervisor program can select and send the appropriate APDUs to the SIM applet. So, in this way we can make the data exchange between two applets at the different chips.
