byte[] ultraigh_pwd_auth(byte noBlock, byte[] pwd)

byte[] ultraigh_read_page(byte noBlock)

void ultraigh_write_page(byte noBlock, byte[] inBuf, int inLen)

you can use above 3 to access ultralight card.

if you want to use APDU  , you can use this.

byte[] transmit(byte[] sendBuffer, int sendBufferLength)

Hello, but this method:

byte[] transmit(byte[] sendBuffer, int sendBufferLength)

triggers errors, because i also tried a quick read using 0x30, but there was no luck.
If there is any sample code of how to send and decode the low level commands. It would be a great help.

Thanks

Yeah, Thanks for pointer,
I have been using the 10th point to send the command. I have tried with the GET_VERSION commmand (0x60) but I keep getting the error: cpu_transmit return error code = -1009
and com.common.apiutil.CommonException.

How can I go about this error:

thanks
