https://devzone.nordicsemi.com/f/nordic-q-a/90523/integrate-custom-uart-protocol-with-mcumgrHi, We have a project that has a custom protocol over UART. We also would like to use MCUMgr over UART as well. What would be the recommended method to integrate the two? Or would I need an additional layer on top that routes the UART messages dependingen-USTelligent Community 13Fri, 29 Jul 2022 20:30:51 GMThttps://devzone.nordicsemi.com/thread/379377?ContentTypeID=1Fri, 29 Jul 2022 20:30:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:86207e11-5d90-4ac1-b6ab-c896037076a8mablabs<p>Never mind - it looks like there are a few examples on DevZone that demonstrate how an application can enter MCUBoot, which makes handling both MCUMgr packets and custom packets over UART unnecessary.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/379352?ContentTypeID=1Fri, 29 Jul 2022 14:43:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fb350983-6e5b-4e82-b297-085440ca2abamablabs<p>To clarify, the additional layer would determine whether the message is for MCUmgr. If it is it would route it to the MCUmgr subsystem, otherwise&nbsp;it would forward it to our protocol processing scheme.</p><div style="clear:both;"></div>
