https://devzone.nordicsemi.com/f/nordic-q-a/126801/data-length-extension-on-nrf52840-dongleHi, I have flashed hci_usb example on nrf52840dongle(hci1), enabled DLE. But when linux machine requests data from other board(as sender) dongle is getting crashed. The same experiment (receiving the data from other board) is successful with defaulten-USTelligent Community 13Mon, 02 Feb 2026 12:01:11 GMThttps://devzone.nordicsemi.com/thread/560114?ContentTypeID=1Mon, 02 Feb 2026 12:01:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a5d28e47-91ce-43d1-9b25-c7fd47a19113Hung Bui<p>Hi Delart,&nbsp;<br />If you have log please show the log when the dongle is crashed.&nbsp;<br />I would suggest not to start the development with a dongle, please use a DK instead. After you finish developing with the DK you can port the code to the dongle.&nbsp;<br />The dongle doesn&#39;t&nbsp;have the debug port (or you have to solder the debug header and use external debugger to debug)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/560054?ContentTypeID=1Sat, 31 Jan 2026 08:46:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5942cf03-66c2-44e1-8342-f745824536c1Turbo J<p><code>CONFIG_LOG=y</code> usually means you need to increase stack size. Where do you intend to put the logs to on the dongle?</p><div style="clear:both;"></div>
