Android NFC library - Command not recognized
Yes, the NFC library supports sending custom commands to NFC tags.

Your TI RF430 seems to be a ISO/IEC 15693 NFC tag.

From the Android's advanced NFC documentation, in  "Table 1. Supported tag technologies", you should use the NfcV class and in particular, the transceive method to send custom commands.

If you want to use another type of NFC card, you may have to use one of the following transceives commands to interact with them.


NfcA transceive(byte[])
NfcB #transceive(byte[])
IsoDep transceive(byte[])
