I am struggling to properly use FDS module. I am using multiperipheral example, just for a training I would like to make something like this: *en-USTelligent Community 13Tue, 05 Jun 2018 11:28:16 GMThttps://devzone.nordicsemi.com/thread/134716?ContentTypeID=1Tue, 05 Jun 2018 11:28:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0da4a544-be6c-4cf2-9c2d-50754e6c8447Pawel Niedbala<p>Thanks, you are right, I don&#39;t know why have I ignored this. Moving <em>m_deadbeef</em> to globals as a static variable solved the issue.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/134706?ContentTypeID=1Tue, 05 Jun 2018 11:03:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1ba755b3-5a32-4b9c-99c5-238d22c21de7Einar Thorsrud<p>Hi,</p> <p>Your&nbsp;<code>m_deadbeef</code> is not static, and only exist on the stack, so it will no longer exist when&nbsp;<code>button_event_handler()</code> returns. FDS is asynchronous, so it is highly likely that the memory has been overwritten by a subsequent function.</p><div style="clear:both;"></div>
