https://devzone.nordicsemi.com/f/nordic-q-a/73199/nrf5340-setup-and-show-graph-dataHello, I am a beginner, and I have the nRF5340, and I would like to measure how far and how fast data travels. I don&#39;t know how to do my testing with this device. For example, I wanted a graph from which I could see how distance affects the speed ofen-USTelligent Community 13Wed, 24 Mar 2021 17:25:52 GMThttps://devzone.nordicsemi.com/thread/301767?ContentTypeID=1Wed, 24 Mar 2021 17:25:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:41e9593f-f7af-48e8-b3db-8fe9e4c50691awneil[quote userid="86953" url="~/f/nordic-q-a/73199/nrf5340-setup-and-show-graph-data"] I am a beginner[/quote] <p>Do you have experience with any other microcontroller(s) ?</p> <p><span>Do you have experience with&nbsp;programming in general ?</span></p> [quote userid="86953" url="~/f/nordic-q-a/73199/nrf5340-setup-and-show-graph-data"]how fast data travels[/quote] <p>Radio waves propagate at the speed of light?</p> [quote userid="86953" url="~/f/nordic-q-a/73199/nrf5340-setup-and-show-graph-data"]how distance affects the speed of packet transmission[/quote] <p><span><span>What do you mean by that?
