https://devzone.nordicsemi.com/f/nordic-q-a/4069/nrf51822-high-current-consumptionHello, i know its an often discussed topic but i already read lots of threads about it and didnt find the answer. I have a simple program that enables the softdevice s110 and then goes into a loop with sd_app_evt_wait(); thats all the system doesen-USTelligent Community 13Tue, 14 Oct 2014 10:13:41 GMThttps://devzone.nordicsemi.com/thread/14593?ContentTypeID=1Tue, 14 Oct 2014 10:13:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:20f186d7-26ef-403b-bc3b-e30751ece3edMatthias<p>Thank you so much! It´s now the 4th day i´m trying on that problem. Adding the external crystal solved the problem! I now found out that it is written in the documentation as well...so that was obviously a little stupid of me!

The softdevice init is hanging while trying to start the external crystal.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/14591?ContentTypeID=1Tue, 14 Oct 2014 06:39:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ec410643-3fc3-4f46-9730-c4cfbdd270ebMatthias<p>Hello, hfclk and lfclk are both RC. Thats correct.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/14590?ContentTypeID=1Mon, 13 Oct 2014 13:28:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:25a6f26d-61c9-47d6-9736-b318161dad06H&#229;kon Alseth<p>You mention that you have no external oscillators, does this include the external 16M crystal? You have also changed the 32 kHz source to the synthesized- or 32k RC source?</p><div style="clear:both;"></div>
