Timeslot interrupt latency

[wizath]

Hello,

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).

Hi Wizath,

If your application requires lower latency, you can think of setting up your application to work as a bootloader. 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 -> softdevice -> Application.

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.
