https://devzone.nordicsemi.com/f/nordic-q-a/59126/er5-could-not-process-mesh-packetI am currently working on a project based on the light_switch mesh example and am running into an issue where I&#39;m receiving several of the following error throughout operation: [er5] Could not process mesh packet... er5 refers to NRF_ERROR_NOT_FOUNDen-USTelligent Community 13Tue, 17 Mar 2020 12:52:55 GMThttps://devzone.nordicsemi.com/thread/240258?ContentTypeID=1Tue, 17 Mar 2020 12:52:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d73321ce-4eb0-4145-bceb-5adea625e2d3Hung Bui<p>Do you have a lot of mesh traffic around ?&nbsp;<br />Could you give some more information about the setup ? How many device did you use ? Did you use the phone to test ?&nbsp;<br />Could you capture a full log when you see the issue ?&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/240141?ContentTypeID=1Mon, 16 Mar 2020 22:25:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1d0b06c8-fe44-4058-81fc-99f06c1059b4Inti3456<p>I see it with nearly every transaction of mesh messages. Usually for every Unencrypted data I get, I get 2 or so of those error packets.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/240101?ContentTypeID=1Mon, 16 Mar 2020 16:27:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bf8d54bf-a5d2-4bd9-a854-2ad3e714b76dHung Bui<p>Hi Inti,&nbsp;</p> <p>How often do you see the &quot;<span>[er5] Could not process mesh packet...&nbsp; &quot; ?&nbsp;<br />We have seen that occurred&nbsp;occasionally as well. It&#39;s can be either from from corrupted packets or packets from other network. So any packet that passed CRC and has the right Mesh flag in the advertising type will get to&nbsp;packet_in().&nbsp;<br />When&nbsp;net_packet_decrypt() couldn&#39;t decode the message, it will throw&nbsp;NRF_ERROR_NOT_FOUND</span></p><div style="clear:both;"></div>
