https://devzone.nordicsemi.com/f/nordic-q-a/41452/how-to-disable-ble-data-whiteningDear Sir We will like to disable the BLE advertising data whitening, could you advise us how to disable it? We have tried to modify the following 0x1UL to 0x0UL and looks like it doesn&#39;t work. nrf52_bitfields.h #define RADIO_PCNF1_WHITEEN_Msken-USTelligent Community 13Tue, 11 Dec 2018 12:17:41 GMThttps://devzone.nordicsemi.com/thread/161188?ContentTypeID=1Tue, 11 Dec 2018 12:17:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:458dd189-3c0c-4685-a3a5-0e341f8e16f4Kenneth<p>To measure radio parameters&nbsp;you should use the DTM project:<br /><a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/ble_sdk_app_dtm_serial.html?cp=4_0_0_4_4">http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/ble_sdk_app_dtm_serial.html?cp=4_0_0_4_4</a>&nbsp;<br /><br /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/161135?ContentTypeID=1Tue, 11 Dec 2018 08:55:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a7374670-1e79-4451-b686-30adcfafaf01andyyang<p>For several BLE test, such as receiver sensitivity, modulation, power test, we may need to turn off the whitening.</p> <p>We will also like to check the frequency deviation, not sure if we need to disable the whitening or now.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/161129?ContentTypeID=1Tue, 11 Dec 2018 08:36:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:212db708-88a0-4faf-9125-24e04acf2387awneil[quote userid="75763" url="~/f/nordic-q-a/41452/how-to-disable-ble-data-whitening"]We will like to disable the BLE advertising data whitening[/quote] <p>Why do you want to do that?</p> <p>Won&#39;t that break Bluetooth compliance?</p> <p><a href="http://www.catb.org/esr/faqs/smart-questions.html#goal">www.catb.org/.../smart-questions.html</a></p><div style="clear:both;"></div>
