DTM and softdevicehttps://devzone.nordicsemi.com/f/nordic-q-a/3489/dtm-and-softdeviceHello When refering to the documentation its stated: &quot;The DTM application is stand-alone. Therefore the S110 SoftDevice must be erased in the nRF51822 device. &quot; Is this entirely true, or is it just enough to disable the softdevice ?

Have a write to that characteristic trigger going from normal mode to DTM mode. The example @michael.crapse pointed out how to do this on a button press. No reason you couldn&#39;t do the same on a write to a specific characteristic.</p><div style="clear:both;"></div>RE: DTM and softdevicehttps://devzone.nordicsemi.com/thread/12640?ContentTypeID=1Wed, 09 Sep 2015 15:19:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cf829eaa-9274-447b-a76a-56154cf12da4sdrest<p>Are any other way to switch Normal mode and DTM mode? there is no GPIO pin except uart on my product...</p><div style="clear:both;"></div>RE: DTM and softdevicehttps://devzone.nordicsemi.com/thread/12638?ContentTypeID=1Fri, 15 Aug 2014 14:32:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4b7345d4-c661-4fce-ae62-575392cf0047John<p>Michael is correct, to elaborate further I&#39;ll describe what we do. DTM is used in production testing. When our device powers up the first thing we do in main is to check the state of a GPIO pin. If it is high we proceed to start the soft device and run &quot;normally&quot;. If the pin is low we do not start the soft device and instead boot into DTM mode and allow DTM to control the radio. The soft device is always programmed.</p><div style="clear:both;"></div>RE: DTM and softdevicehttps://devzone.nordicsemi.com/thread/12637?ContentTypeID=1Thu, 14 Aug 2014 18:20:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:200e36c9-327a-4e9e-94d0-1cbe437cc8f5michael.crapse<p>Yes, You can just disable the soft device. There is an example code located at nrf51822/Board/nrf6310/s110/ble_dtm</p><div style="clear:both;"></div>
