Topic: DL533N Reader/Writer - using two devices simultaneously | libnfc
I experience a problem when connecting two DL533N Reader/Writer to my virtual machine.
When I run the tool nfc-relay from the examples provided by libnfc, the program stops working after printing the following output:
niklas@niklas-ubuntu-virtualbox:~$ nfc-relay nfc-relay uses libnfc 1.7.1 Hint: tag <---> initiator (relay) <---> target (relay) <---> original reader NFC emulator device: NXP / PN533 opened [+] Try to break out the auto-emulation, this requires a second reader! [+] To do this, please send any command after the anti-collision [+] For example, send a RATS command or use the "nfc-anticol" tool
In addition to that, pn53x-diagnose detects the following error:
niklas@niklas-ubuntu-virtualbox:~$ pn53x-diagnose pn53x-diagnose uses libnfc 1.7.1 NFC device [NXP / PN533] opened. Communication line test: OK ROM test: OK RAM test: OK NFC device [NXP / PN533] opened. error libnfc.driver.pn53x_usb Unable to receive data: buffer too small. (szDataLen: 1, len: 8) pn53x_transceive: cannot diagnose communication line: Input / Output Error ROM test: OK RAM test: OK
Does anyone know the reason behind this problem and a possible workaround for it?
