Can you please post your config settings for RX and TX. Thanks.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/713?ContentTypeID=1Wed, 31 Jul 2013 12:30:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:43df8e41-bb75-4414-ba60-28d868f3fd09H&#229;kon Alseth<p>Hi,</p> <p>It seems that your configuration is OK as you are able to send and receive ACK payload. On the PTX side, you receive the payload, but the payload length is wrong?</p> <p>ACK payloads should be read out as a normal PRX reads out payloads. The &quot;R_RX_PL_WID&quot; command byte is &quot;0x60&quot;, but this does not mean that the returned length this value. I believe that you are not reading the register &quot;R_RX_PL_WID&quot; correctly. Do you see the same issue on PRX when reading &quot;R_RX_PL_WID&quot; ?</p> <p>Best regards Håkon</p><div style="clear:both;"></div>
