https://devzone.nordicsemi.com/f/nordic-q-a/88899/nrf9160-nb-iot-current-consumption-in-idle-modeHi, I&#39;m trying to get a better understanding what causes some unexpected current peaks while nRF9160 is in RRC-IDLE with the NB-IoT mode. I have been experimenting with the UDP sample with and without eDRX with data transfer interval of 1 minute (10en-USTelligent Community 13Wed, 15 Jun 2022 06:05:37 GMThttps://devzone.nordicsemi.com/thread/372469?ContentTypeID=1Wed, 15 Jun 2022 06:05:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f225dba1-17c0-4342-9bae-b27177135b8coapilo<p>Hi Dejan,</p> <p>Thank you for the explanation.

Synchronization is done with the cell before receiving paging information.<br /><br />Best regards,<br />Dejan</p><div style="clear:both;"></div>
