https://devzone.nordicsemi.com/f/nordic-q-a/10985/how-much-space-do-app-timers-needI have a question about how much memory is required for app timers. The comments for APP_TIMER_BUF_SIZE state that the buffer size must be one more than actually needed. Hence, the macro adds a +1 to OP_QUEUES_SIZE before calculating buffer size. en-USTelligent Community 13Tue, 22 Dec 2015 12:53:20 GMThttps://devzone.nordicsemi.com/thread/41076?ContentTypeID=1Tue, 22 Dec 2015 12:53:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:814f5d7b-7334-499e-82dd-736d4518612cHung Bui<p>Hi Branden,</p> <p>I agree, seems like a mistake. I have reported this internally. I believe we only need to call APP_TIMER_BUF_SIZE(OP_QUEUES_SIZE) when in APP_TIMER_INIT.</p> <p>Thanks for noticing.</p><div style="clear:both;"></div>
