https://devzone.nordicsemi.com/f/nordic-q-a/41553/about-wdt-with-only-ble-empty-packet-communicationHi Nordic, I am using SDK 12.3.0, S130 2.0.1 and PCA10028 nrf51 DK. I would like to ask about WDT and softdevice (centre). The WDT setting is 2s timeout and the WDT counter would be paused during sleep and halt.

Look at&nbsp;\components\ble\ble_radio_notification in the nRF5 SDK.</p><div style="clear:both;"></div>
