Succesfull SendReceive write command to Mifare Ultralight EV1 sometimes responds with succes code, sometimes with error code

Error - 8700 : Frame wait time out OR no tag

Even though a writeis succesfull, I will at one time get this error code back (this is the answer of the SendReceive, the result of SendReceive itself is errorcode '4 ' which stands for Communication Error), and another time a succes code. I know the write is succesfull because in the next read I can read the value that was written.

The problem with this is that I cannot check whether or not the write was succesfull and then try again, because this may put me in an infinite loop.

What can be the cause of this?
