I have an Arduino reading data from my Android phone via a PN532, I documented my code here:

https://forum.arduino.cc/t/using-an-android-phone-to-send-same-string-to-arduino-via-nfc/967984/7?u=wrybread

I'm trying to send an NDEF string using the Android app NDEF Tag Emulator, but the Arduino reports this error whenever it reads from my phone:

Unknown TLV 6E
Error. Can't decode message length.
ERROR
UID: 08 CB E1 F4

I don't imagine anyone has any ideas?

Like many people here I'm trying to use an Android phone to unlock a door, but am having trouble getting the phone to send a unique string.
