The tutorial files provided contain 10028 and 10040 but not 10031en-USTelligent Community 13Wed, 28 Sep 2016 08:08:08 GMThttps://devzone.nordicsemi.com/thread/63910?ContentTypeID=1Wed, 28 Sep 2016 08:08:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8fe37a81-0ced-40aa-9b73-a62b47de07a9J&#248;rgen Holmefjord<p>The chip in PCA10031 is the same as PCA10028. You should therefore be able to use the tutorial and change the PCA10028 project to work with the PCA10031 board. The project uses the BSP package to handle the different pinouts to leds and buttons.</p> <p>By changing the define in pre-processor symbols in C/C++ tab in project options from BOARD_PCA10028 to BOARD_PCA10031. I have only tested on the characteristics tutorial, and here I needed to change LED_4 in step 3.F to BSP_LED_2 to make the project compile without warnings.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/63911?ContentTypeID=1Tue, 27 Sep 2016 19:36:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a9616ae2-0904-4a2f-b9a8-0afa2c3b2304e.plotkin<p>You can use <a href="https://www.bluetooth.com/develop-with-bluetooth/developer-resources-tools/bluetooth-developer-plugins">Bluetooth Developer Studio</a> for generate custom characteristics and services. And also you can debug your cutsom project if have a PTS doungle.</p> <p>Main core similar 10028, but need looking on your revision chip</p><div style="clear:both;"></div>
