The most I can get through is about 640 kbit/s with UDP (about 65 packets peren-USTelligent Community 13Mon, 19 Oct 2026 16:33:48 GMTRE: nRF9151 DECT NR+ maximum throughput of mac+phy firmwarehttps://devzone.nordicsemi.com/thread/572376?ContentTypeID=1Mon, 19 Oct 2026 16:33:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f7cd3802-caa0-4ead-9b05-81edb3a386feSyed Maysum Abbas Zaidi<p>Hi,</p> <p>Thanks for reaching out. Before I answer whether 640 kbit/s is the expected maximum, could you help me with three things?<br />1. Your prj.conf and any devicetree overlay.<br />2. For the 2.4 Mbit/s dect_shell result, did you build it with the iperf3 overlays, or with the default config? and also how are the two PCs connected to the DKs?</p> <p>Best Regards,<br />Syed Maysum</p><div style="clear:both;"></div>
