[a-panda]

Functionalities have been added to emulate a tag.

This has been tested on Arduino Uno with a PN532.

Do you have an example for NDEF record that I can pass in sendbuf?

@a-panda your example doesn't work for me. I think trouble may be in TgInitAsTarget. When command sends to PN532, it not answer and timeout comes. Can u help me find a solution?

Hello. I am having the following issue. I am using an Arduino Uno with an Adafruit PN532 and am attempting tag emulation utilizing this PR. When I use my iPhone XR with NFC tools to try and read the PN532 in emulation mode (using the SImpleTag example given) I get this on the Serial Monitor:

But I get this on NFC tools:

I am not sure what is wrong or if the problem is on the PN532 side or the phone side. I have tried with other apps and get similar reactions. Any help would be greatly appreciated.

^update. I additionally tried with another app, NFC TagInfo and get a Connection Error - Stack Error. Any idea what this means? Thanks in advance.
