Hi, I have used npp_test_server.py to communicate between RC-S370 and Nexus S, it works fine. After reading the source, I found nfcpy is using 424 kbps active mode. for testing, I adapted the setting to 106 kbps passive mode as below: pn53x.py 585 rsp = self.dev.in_jump_for_dep("active", "424", pollrq, nfcid3, general_bytes) -> rsp = self.dev.in_jump_for_dep("passive", "106", "", nfcid3, general_bytes) and I got an error because of no reponse from Nexus S. Does nfcpy support passive mode? or Nexus S can only work at 424 kbps active mode? Any information will be appreciated. Thanks, Jun ------------------------------------------------------------------------------------------------------ 2011-09-12 16:03:08,390 INFO [nfc.dev.pn53x] searching for a usb bus reader
