Dear Antonio Cinelli,
the NCI examples we provide for 7150 already detect Type B tags ( the part number from ST you mention are ISO 14443-B) I am not sure why you mention not NFC compliant maybe it is other Part number please clarify this to me, but since our products are Type A our example only shows basic information from the tag, for more interaction you will need to modify the example or create your own in order to interact with Type B more than just detecting it.
you can see under nfc_task.c when you define the TECH_PASSIVE_NFCB
case (MODE_POLL | TECH_PASSIVE_NFCB): if(RfIntf.Info.NFC_BPP.SensResLen != 0) print_buf("\tSENS_RES = ", RfIntf.Info.NFC_BPP.SensRes, RfIntf.Info.NFC_BPP.SensResLen); break;
please check this examples.
