https://devzone.nordicsemi.com/f/nordic-q-a/38621/long-range-connection-between-2-52840-modules-with-pcb-antennaI have 2 52840 modules with PCB antenna and I am trying to check the max connection range I followed the recommendations and achieved only 120m. I cannot use the examples that require DK, so, I would appreciate if you can direct me to a code thaten-USTelligent Community 13Wed, 19 Sep 2018 08:23:58 GMThttps://devzone.nordicsemi.com/thread/149357?ContentTypeID=1Wed, 19 Sep 2018 08:23:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4be9b5ee-5909-4f36-82bc-ff63d85dd9a5ovrebekk<p>Hi</p> <p>The following blog has some information about long range testing:<br /><a href="https://devzone.nordicsemi.com/b/blog/posts/testing-long-range-coded-phy-with-nordic-solution-it-simply-works-922075585">https://devzone.nordicsemi.com/b/blog/posts/testing-long-range-coded-phy-with-nordic-solution-it-simply-works-922075585</a></p> <p>I don&#39;t think switching from SDK15.0 to SDK15.2 is going to make a difference on range.&nbsp;</p> <p>If you are testing ble_app_uart at the standard 1Mbps bitrate you could try to use your nRF52 DK on one end to see if it makes a difference.&nbsp;<br />120m range doesn&#39;t sound too bad for 1M, but if you are testing with the long range phy I agree it sounds low.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/149252?ContentTypeID=1Tue, 18 Sep 2018 13:29:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:afb9dba7-7bbc-418a-ada3-47d444d282e6Avi<p>One more update - I used SDK15.0 with&nbsp;<span>s140 6.0.0</span></p> <p>I noticed that now there is an updated version - would that fix the range problem?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/149250?ContentTypeID=1Tue, 18 Sep 2018 13:28:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c686808c-035e-4d2f-bfeb-65db94f619e3Avi<p>I used:&nbsp;<span>ble_app_uart</span></p> <p>with +8dbm</p> <p>The link bit rate is 1 byte ber second</p> <p>I don&#39;t have information from the manufacturer, I guess that by that time there was no ref design for testing long range.</p> <p>I currently have only 832DK .&nbsp;</p> <p>Is there a way to make a short example that can be programmed to my two modules in order to check range?</p> <p>I think it would be helpful to many others</p> <p>Thank you</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/149246?ContentTypeID=1Tue, 18 Sep 2018 13:17:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:23beaf9a-a89b-4ed1-9be5-70288d0f99ecovrebekk<p>Hi&nbsp;</p> <p>What example were you using to test the range, and what bitrate was the link running at?</p> <p>Also, what was the TX output power?</p> <p>Have you tried contacting the module vendor to ask what condition they tested the range under, if any?</p> <p>If you don&#39;t have a regular nRF52840 DK to compare I would suggest getting it, even if you just get a single one. Then you can compare the signal strength from the kit to your module, and having one will greatly simplify your development anyway.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
