https://devzone.nordicsemi.com/f/nordic-q-a/12141/flash-write-problemHi, We are using Softdevice S310 Version:3.0.0 and SDK:9.0.0. My Device working on battery power. We are facing Flash write problem when my battery voltage goes to below 2.7V. We are set below threshold. //Power Threshold Set err_code = sd_power_pof_threshold_seten-USTelligent Community 13Wed, 02 Mar 2016 07:22:22 GMThttps://devzone.nordicsemi.com/thread/45927?ContentTypeID=1Wed, 02 Mar 2016 07:22:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:281373d2-2386-46e2-97ff-b367dff8eff5Einar Thorsrud<p>No problem.

You are specifying that the power should not go below 2,7 V, so then this is expected behaviour.</p> <p>Is there a particular reason why have you set <code>NRF_POWER_THRESHOLD_V27</code>? If you set it to a other value, say <code>NRF_POWER_THRESHOLD_V23</code>, that should help.</p><div style="clear:both;"></div>
