https://devzone.nordicsemi.com/f/nordic-q-a/84419/nrf5340-interprocessor-communication-without-using-openampHello! I am evaluating using nrf5340 for a very simple application (literally would only be a few lines of code). In it, I want to pass some information from the network core to the application core. I know that I can signal the application core thaten-USTelligent Community 13Mon, 07 Feb 2022 12:39:29 GMThttps://devzone.nordicsemi.com/thread/351528?ContentTypeID=1Mon, 07 Feb 2022 12:39:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6ab02f39-efd3-4578-a8a7-7ab8fa0160b9Sigurd<p>Hi,</p> <p>First of all, I strongly&nbsp;recommend using Zephyr and our nRF Connect SDK when working with the nRF5340.&nbsp;<a href="http://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.8.0/nrf/ug_nrf5340.html">http://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.8.0/nrf/ug_nrf5340.html</a></p> <p>Here is a sample that show use to use&nbsp;RPMsg Service: <a href="https://github.com/nrfconnect/sdk-zephyr/tree/main/samples/subsys/ipc/rpmsg_service">github.com/.../rpmsg_service</a></p> [quote userid="104009" url="~/f/nordic-q-a/84419/nrf5340-interprocessor-communication-without-using-openamp"]Therefore, what would be the way for the application core to receive correctly data from the network core?[/quote] <p>We don&#39;t have any examples for this.
