I'm developing an android application that uses the RFD8500 sled:
 
1 When the trigger is pulled
2 Reads the RFID tag ID
3 Writes data to the RFID tag user space
4 Reads back the data from the RFID tag just written
 
But I get the following error when writing and I'm not sure what it even means:
 
RFID_ACCESS_TAG_WRITE_FAILED
access no response from tag
 
It's intermittent, sometimes I get the above error and sometimes I don't. Is it still caught in a state of reading the tag when writing? If so how can I wait for that to clear?
