Dear All

I am currenty evaluating the SAM example provided in the support page of EMDK for Xamarin 8.0.
I am using a TC21 Handheld Computer with Android 11 and I try to read a DESFire EV2 8k tag.
I tried to read the tag with the NFC Tool app and it provided me with a few details of the tag that is:
Type, serial number Available tecnology and so on.

On the other hand, the sample code runs but I only get the compatible tecnology (mifare) and nothing else since I get a few errors I don't quite understand.

For instance, during the Initialization of the Sam Manager  I often get an unsupported feature error, whereas during the enumeration of SAMs I get an exception.

To be specific, at the execution of the line of code:
samManager = (SAMManager)emdkManager.GetInstance(EMDKManager.FEATURE_TYPE.Sam);
I get the error
[SAM_Manager_Helper] #EMDK-API# SAMManagerHelper::Caught exception : Unsupported feature. 

also, duting the execution of the line:
samList = samManager.EnumerateSAMs();
I get the exception
SAM Exception: Symbol.XamarinEMDK.Sam.SAMException: Failure.

Could you kindly shed some light on those issues?

Kindest regards.

Marco
