Do you use the softdevice? Is there a BLE connection?</p> <p><strong>Update 10.02.2017:</strong> The reason for the reset when calling __enable_irq() is that there are too many interrupt that has happened and the softdevice doesn&#39;t know handle that situation.</p> <p>Instead of using __disable_irq() and __enable_irq(), I would recommend you to use CRITICAL_REGION_ENTER() and CRITICAL_REGION_EXIT(). CRITICAL_REGION_ENTER/EXIT call sd_nvic_critical_region_enter/exit. sd_nvic_critical_region_enter disables all application interrupts, but handle the radio interrupts, so that the BLE link is kept.</p><div style="clear:both;"></div>
