https://devzone.nordicsemi.com/f/nordic-q-a/42658/relationship-between-speed-and-reliabilityHello Nordic, we use the nrf52 proprietary protocol in the project, it will send 200 data per second, and no ack confirmation, the application data length is 25 or 32 bytes. I am not sure if I should use 1mbps or 2mbps. Here is my understanding of theseen-USTelligent Community 13Thu, 17 Jan 2019 14:56:07 GMThttps://devzone.nordicsemi.com/thread/166293?ContentTypeID=1Thu, 17 Jan 2019 14:56:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2ea0527c-6b73-458c-ba27-7034bb19bf5aovrebekk<p>Hi</p> <p>I can&#39;t really give you a definitive answer to this question.&nbsp;</p> <p>If the distance between devices is 10m or more, or there are walls in between them,&nbsp;then 1Mbps will probably give you better performance. <br />On the other hand if range is short and you have heavy interference from WiFi then 2Mbps might be better, because the packets are shorter as you say.&nbsp;</p> <p>In either case I would recommend sending each packet several times (ideally on different frequencies), to reduce the impact of packet loss.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/166195?ContentTypeID=1Thu, 17 Jan 2019 11:19:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d8ca5dcc-4de4-43b7-8a27-b2ebc573f0c1Kevins<p>I need to explain that the transmitter transmits 200 times per second, and the application packet length of each transmission is 25 or 32 bytes.</p><div style="clear:both;"></div>
