(6) Request Resend (RRES)<br />
This command instructs the reader to re-send the latest response data that has been sent. This command shall<br />
not be accepted when the other command such as Repeat mode is being processed.<br />
Command RRES<br />
Note: No argument<br />
Response The latest response<br />
* If there is no the latest response data, the error is returned [Code:1500].<br />
* When the communication mode is SRP/MRP, it can be accepted. However, if the timeout value is small<br />
(timeout interval is too short), the reader can not afford to identify various responses returned<br />
continuously.<br />
Example 1) When the host requests to resend the response for the successful single ID read command (RDID<br />
-seq SOC -ant 1 -tif EPC,ANT) that has been executed most lately:<br />
