We are planning to do a EMC test on our device that is using nRF52832, the test facility requires us to provide a programming interface that can change the frequency of the radio to test across the full range, does the SWD interface ofen-USTelligent Community 13Thu, 28 May 2020 12:33:27 GMThttps://devzone.nordicsemi.com/thread/252177?ContentTypeID=1Thu, 28 May 2020 12:33:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3f41b509-240f-4ee0-a8ed-410b4c1ccc32Simonr<p>Hi William</p> <p>You can check out the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/ble_sdk_app_dtm_serial.html">DTM example documentation</a> for details on how to set up and run the example.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/252053?ContentTypeID=1Wed, 27 May 2020 21:47:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:152f6aa7-facb-4427-b4fe-881f7c0365d7William Geng<p>Thanks! I wasn&#39;t aware of the DTM, so does that mean for that I will just need any two GPIO configured as UART and run the DTM example on it?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/252049?ContentTypeID=1Wed, 27 May 2020 20:49:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ef8902d1-a6a6-4fb6-8671-89928c95ad1aTurbo J<p>Any reason why you don&#39;t just use the DTM (direct test mode) example?</p> <p></p> <p>Yes, SWD can change the RADIO, but good luck writing those JLINK scripts.</p><div style="clear:both;"></div>
