https://devzone.nordicsemi.com/f/nordic-q-a/59921/ble-peripheral-delayed-communicationHello, We have designed a PLE peripheral based on nRF52840, SDK16.0, Softdevice v7.0.1. We have having an issue where, occasionally, we send a certain data (a command) to the peripheral and it receives the data after extended delays like 5-10 secondsen-USTelligent Community 13Tue, 07 Apr 2020 11:02:39 GMThttps://devzone.nordicsemi.com/thread/243870?ContentTypeID=1Tue, 07 Apr 2020 11:02:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4259b941-9e86-4be2-b693-ef09e18d650aKenneth[quote user=""]This particularly happen when central is far away from the peripheral. [/quote] <p>Doesn&#39;t this explain all your problems? When at the edge of the link the packet&nbsp;loss increase rapidly, you barely have some communication, moving a few meters further away and the link is lost, moving a few meters closer and there is no packet loss. All packets will be retried until link is lost or packet is sent successfully.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
