https://devzone.nordicsemi.com/f/nordic-q-a/20500/timeslot-interrupt-latencyHello, Is there any way to mitigate delay of redirecting interrupts from softdevice to application? Using nRF51 with S130 there is ~2us delay even with SoftDevice disabled (as stated in SD documentation).

This mean your application/bootloader will receive the interrupt forwarding directly from the MBR, which save you some time because for normal application it will be MBR -&gt; softdevice -&gt; Application.</p> <p>Please refer to our DFU bootloader to see how it works and how you can forward back the interrupt to the softdevice by initializing it using SD_MBR_COMMAND_INIT_SD MBR command.</p><div style="clear:both;"></div>
