Maybe you can keep your SPI code the main loop and just set a flag during the BLE events. Have you looked at some of the other <a href="https://devzone.nordicsemi.com/questions/scope%3Aall/sort%3Arelevance-desc/page%3A1/query%3Aspi%20softdevice/">threads</a> here on devzone discussing how to use SPI and a Softdevice concurrently?</p><div style="clear:both;"></div>
