Activate DTM over the air interfacehttps://devzone.nordicsemi.com/f/nordic-q-a/22852/activate-dtm-over-the-air-interfaceHi, I&#39;m wondering if the DTM mode can be entered over the air interface on nRF bluetooth products, as specified by Core4.2 [Vol2 Part C] 4.7.1 Activation and Deactivation of Test Moden-USTelligent Community 13Fri, 16 Jun 2017 10:47:59 GMTRE: Activate DTM over the air interfacehttps://devzone.nordicsemi.com/thread/89840?ContentTypeID=1Fri, 16 Jun 2017 10:47:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c1dca90b-c19f-4fe7-b777-5b64f489eb22J&#248;rn<p>Hello saintnever</p> <p>As endnode stated the test mode you refer to is not for Bluetooth Low Energy. Vol 2 of the Bluetooth 4.2 specification only relates to BR/EDR (Basic Rate/Enhanced Data Rate, AKA. Bluetooth classic).</p> <p>DTM (Direct test mode) for BLE is described in Volume 6, part F, and does not support OTA activation.</p> <p>You can find an example for DTM in the SDK examples folder, and documentation for the example can be found <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v13.0.0/ble_sdk_app_dtm_serial.html?cp=4_0_0_4_3">here</a></p> <p>Best regards</p> <p>Jørn Frøysa</p><div style="clear:both;"></div>RE: Activate DTM over the air interfacehttps://devzone.nordicsemi.com/thread/89841?ContentTypeID=1Fri, 16 Jun 2017 08:10:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:88bdb01e-2c25-47a2-8dcb-c4e6419e4e91endnode<p>I&#39;m afraid this Test Mode isn&#39;t BT LE DTM. At least there is nowhere <code>DTM</code> mentioned and all links point to BR/EDR.</p><div style="clear:both;"></div>
