Long Range issue in nrf52840 CODED PHY modehttps://devzone.nordicsemi.com/f/nordic-q-a/97333/long-range-issue-in-nrf52840-coded-phy-modeHi Guys, We are developing a peripheral node and a gateway using nrf52840, we procured Adafruit itsy bitsy nrf52840 boards having Raytac MDBT50Q modules (ceramic antenna) we were using Arduino environment earlier then we shifted to the latest nrfen-USTelligent Community 13Mon, 06 Mar 2023 11:59:03 GMTRE: Long Range issue in nrf52840 CODED PHY modehttps://devzone.nordicsemi.com/thread/413501?ContentTypeID=1Mon, 06 Mar 2023 11:59:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:386d32fb-da43-44ab-8614-45cc82dde8caSusheel Nuguru<p>That seems strange.&nbsp;<br />Have you double checked (using sniffer) that your device indeed is running in CODED_PHY mode?&nbsp;</p> <p>Testing with two concrete walls might also be very tricky if they absorb most of the signal, but you should have seen some improvement.</p> <p>If you have nRF52840 DK, can you do the same test on them and see what results you achieve? We can then focus either on hardware or firmware based on your results of this test.</p> <div style="left:-11px;top:-6.4px;"> <div></div> </div><div style="clear:both;"></div>RE: Long Range issue in nrf52840 CODED PHY modehttps://devzone.nordicsemi.com/thread/413376?ContentTypeID=1Sun, 05 Mar 2023 06:21:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ad316509-7d5c-4d10-8650-ae96ae3f45d2KamalpreetS<p>We are using the maximum transmission power +8db&nbsp;</p><div style="clear:both;"></div>
