Wake UP TWI from System Offhttps://devzone.nordicsemi.com/f/nordic-q-a/52006/wake-up-twi-from-system-offHello. I am trying to use TWI with mpu9250 sensor after System Off mode. But it is not working well. Do I need to do some preparation before going to System off mode? Where the start point after wake up?en-USTelligent Community 13Thu, 12 Sep 2019 05:34:48 GMTRE: Wake UP TWI from System Offhttps://devzone.nordicsemi.com/thread/209288?ContentTypeID=1Thu, 12 Sep 2019 05:34:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3df0cd99-c4e1-4aef-9ccd-16e183f3d89eNamoAton<p>There is a strange behavior of MPU9250 sensor too. May be something wrong with timing or somtehing else. Anyway if reset after &quot;cold&quot; start system everything work well. Strange things...</p><div style="clear:both;"></div>RE: Wake UP TWI from System Offhttps://devzone.nordicsemi.com/thread/209206?ContentTypeID=1Wed, 11 Sep 2019 13:47:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fda1726e-6042-46b5-a17b-6325fc980e24Einar Thorsrud<p>Hi,</p> <p>Can you elaborate on how it is not working well? The nRF is always reset when waking up from system off mode, so seen from the nRF there should not be any difference between a power-on reset and wakeup from system off.</p><div style="clear:both;"></div>
