https://devzone.nordicsemi.com/f/nordic-q-a/62694/distance-measurement-between-two-nrf52840Hello, I am using nRF52840, S140 v7.0.1. We want to measure distance between two nRF52840 with BLE 1 Mbps and 0 dBm. I am referring below two links. In this its mentioned as 248 meters. https://devzone.nordicsemi.com/nordic/nordic-blog/b/blogen-USTelligent Community 13Tue, 16 Jun 2020 12:35:58 GMThttps://devzone.nordicsemi.com/thread/255402?ContentTypeID=1Tue, 16 Jun 2020 12:35:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5750de74-88c2-4105-9833-7d8c1c898c73beemavishnu<p>Thank you for your inputs.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/255401?ContentTypeID=1Tue, 16 Jun 2020 12:32:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6f5b04ce-038e-4dc8-af74-3541b787d761Sigurd<p>Hi,</p> <p>Estimating range is very difficult, and it&nbsp;strongly depends on the environment the devices are in. E.g. Outdoor, indoor,&nbsp;Line-of-sight or not,&nbsp;2.4GHz RF Interference/noise,&nbsp;how good the antenna is tuned, etc</p> <p>Note that in the first link(248m), testing was done with a Samsung S8 and nRF52840 DK, but in the second link(654m), 2 nRF52840 DKs was used. That could effect the range. Also note that the&nbsp;654.92m test was done outdoors, line-of-sight, and in a very low noise RF&nbsp;<span>environment.</span></p> <p>BR,</p> <p>Sigurd</p><div style="clear:both;"></div>
