But you should still describe what exactly you do, and what exact error messages and/or other behaviour you experience.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/56866?ContentTypeID=1Mon, 04 Jul 2016 12:51:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:32ecaefb-9086-4f71-810a-7d624cf451edtesc<p>Hi,</p> <p>If you are using SDK v10.0.0 then you should follow the <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk51.v10.0.0%2Fble_sdk_app_multilink.html&amp;cp=5_0_1_4_2_0_1">SDK 10.0.0 documentation</a> (and not the one for SDK v8 which you are linking to).</p> <p>Can you also update your question and describe the problem? Now you are only stating that you get a problem, but you say nothing about what the problem is. It could be anything.</p> <p>Regards, Terje</p><div style="clear:both;"></div>
