If the ESB PTX has the standard 250us repeat interval, will the PTX ever receive the packet or will it timeout before the whole ACK payload hasen-USTelligent Community 13Mon, 01 Apr 2019 09:02:51 GMThttps://devzone.nordicsemi.com/thread/179421?ContentTypeID=1Mon, 01 Apr 2019 09:02:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:580a7d3f-a581-454b-8e7d-bc337767680aSteve H<p>Thanks, <a href="https://devzone.nordicsemi.com/members/kenneth">Kenneth</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/178958?ContentTypeID=1Thu, 28 Mar 2019 13:50:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bc36309b-4364-4444-abc0-532d68cbb670Kenneth<p>Historically you would need to scale the re-transmit delay to ensure it could receive the entire ack payload depending on max size and data-rate. I doubt this has changed since.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
