https://devzone.nordicsemi.com/f/nordic-q-a/11515/51822-52832-how-many-packages-can-send-per-connection-eventHi, I&#39;m learning the BLE protocal these days, I didn&#39;t see the protocal say how may packages can send per connection event. Does it mean that the number of packages is determined by the implementation? If so, what&#39;s the number of 51822/52832. en-USTelligent Community 13Mon, 25 Jan 2016 10:18:39 GMThttps://devzone.nordicsemi.com/thread/43541?ContentTypeID=1Mon, 25 Jan 2016 10:18:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:56236f5a-7422-4659-a4ae-e455fa274555&#216;yvind Karlsen<p>Hi,</p> <p>Please see <a href="https://devzone.nordicsemi.com/question/3440/how-do-i-calculate-throughput-for-a-ble-link/">this answer</a> for some more information. The packet number depends on which SoftDevice you are running. Our most recent SoftDevices support up to 6 packets per connection in each role.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
