Dear Sir/Miss,
I have a problem about NXP PN553 NFC Controller driver porting on android 7.1.0 with iMX6D.
Currently I can able to read NFC tag information but NFC module keep sending 3 bytes 61 23 00 every 10 sec as below:
01-01 00:06:45.494 709-862/com.android.nfc D/NxpNciR: len = 3 > 612300
And I got this error as below:
00:06:45.494 709-842/com.android.nfc E/BrcmNfcNfa: unknown opcode:0x23
Could someone help me to understand why NFC module keep sending 3 bytes?
Please see the full log file in the attached.
Thank you
Danny Lu
I have also encountered this problem, and have you finally come up with a solution? Thank you.
Regarding "61 23 00" NCI notification, it indicates NFC POLL discovery cannot be performed because of missing TVDD supply.
For your information, PN553 is not a mass market product. Please contact local NXP CAS team or local distributor for better support.
