https://devzone.nordicsemi.com/f/nordic-q-a/113856/decrease-cscon-1-timeI am using nRF9160 to develop a mobile measuring device. For this purpose I need LTE and GPS, I know it is shared so I had to implement PSM/eDRX to make it work together. This goes well to a maximum logging frequency of about 13 seconds because GNSSen-USTelligent Community 13Wed, 14 Aug 2024 07:42:35 GMThttps://devzone.nordicsemi.com/thread/498192?ContentTypeID=1Wed, 14 Aug 2024 07:42:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0e5ca34e-0684-43c1-9ea9-8e88b990fa4eralphvn<p>It is correct I am using TCP, and the explanation is clear. For now, I will just leave it and maybe later evaluate using UDP is an option if I really need this time to be reduced.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/497984?ContentTypeID=1Tue, 13 Aug 2024 09:10:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c95ef520-7407-4122-a6f6-bfd1e687ada7Achim Kraus<p>I guess you use TCP. With that, there are potentially more radio-data messages in the air than application data messages passed in. That makes it hard to use RAI (Release Assistance Indication) and it would anyway require to be supported by the MNO. So, if you not willing to switch to UDP, I don&#39;t see, how the RRC active time (after the last message exchange) could be reduced. Some try to use RAI even with TCP, but I&#39;m not aware, that this is used with success.</p><div style="clear:both;"></div>
