If you have the nfctool and dmesg lines from the second > start, that would help. I tried again a bit more yesterday and saw the same behavior. For a few tag scans it appears fine (apart from the bunch of errors in dmesg), but after playing around more, I again got the NFC stack into a state where no further tag scans were possible. I've scanned both a standard r/w NFC tag (ISO 14443-3A, NXP - NTAG216), and sometimes my Android phone, which also got recognized as tag. Looking forward to testing v4.
