Hi Andy,
I gave that patchset v4 a try against Linux v5.3-rc5.
And played with neard and neard-tools v0.16-0.1 from Debian/buster AMD64.
# nfctool --list
# nfctool --enable --device=nfc0
# nfctool --list --device=nfc0
nfc0:
Tags: [ tag11 ]
Devices: [ ]
Protocols: [ Felica MIFARE Jewel ISO-DEP NFC-DEP ]
Powered: Yes
RF Mode: Initiator
lto: 0
rw: 0
miux: 0
# nfctool --device=nfc0 --poll=Both --sniff --dump-symm
Start sniffer on nfc0
Start polling on nfc0 as both initiator and target
Targets found for nfc0
Tags: [ tag11 ]
Devices: [ ]
But I see in the logs:
# journalctl -u neard.service -f
Aug 20 23:01:15 iniza neard[6158]: Error while reading NFC bytes
What does this error mean?
How can I get more informations?
Can you aid with debugging help?
Thanks in advance.
Regards,
