https://devzone.nordicsemi.com/f/nordic-q-a/126228/problem-using-command-line-interface-cli-off-dev-board-radio_test-exampleHi, I have the radio_test example running correctly on a nrf52840 dev board. I am able to use the Nordic Serial Terminal (v1.6.0) to send commands and read responses. I am now trying to run this example on our custom board which uses a BMD-380 moduleen-USTelligent Community 13Thu, 18 Dec 2025 21:05:58 GMThttps://devzone.nordicsemi.com/thread/557375?ContentTypeID=1Thu, 18 Dec 2025 21:05:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:52758acc-595a-4925-acce-d87d5dcb1261mikefraguglia<p>dropping baud rate to 19200 seems to have fixed things! Thanks for the suggestion.</p> <p>I am using an FTDI cable that is ~6ft long so that could be causing some noise.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/557371?ContentTypeID=1Thu, 18 Dec 2025 20:00:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:30e4d58b-f704-41e1-9634-d30a507e3cecAsbj&#248;rn<p>Hi Mike,</p> <p></p> <p>the behaviour you describe sounds like there might be some noise or long traces affecting the performance. Any chance you have a signal analyser at hand and could probe on the signal lines during the commands? Alternatively you can adjust the baud rate to something slower as well that makes the noise less dominant if it is. Are there any voltage differences on the pins compared to the initial DK tests?</p> <p></p> <p></p> <p>Best regards</p> <p>Asbjørn</p><div style="clear:both;"></div>
