Issue 8: Why can't I send data larger than 41 bytes?
  Back to list

It seems the project works perfect and I really appreciate it 

but when I tried to send data larger than 41 bytes, 

the reader java source failed to receive the payload.

Does anyone know what's going on?

The situation is about sending data from phone to acr122 over npp.

I can send 41 bytes data. But never 42 bytes and what's larger.



* Below is the output when it fails to receive : 

[DEBUG] {sending   [50 bytes]} 0xFF 0x00 0x00 0x00 0x2D 0xD4 0x8C 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01 0xFE 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01 0xFE 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x06 0x46 0x66 0x6D 0x01 0x01 0x10 0x00
