Communicate Between Two High-Level Applications

Question

Hi Everyone,

I'm working on a use case that requires two high-level applications to run simultaneously. I have confirmed that I can do this utilizing the "partner application" functionality. However, in my use case I require that each application can communicate with the other. How should this best be accomplished? It looks like only real-time apps and high-level apps have direct communication supported, and I don't have access to stdin/stdout, sockets, or other means of doing this in a POSIX-y way. It also appears that shared mutable memory access isn't supported.

Thanks for your help!

Apps can be listed as "partner applications" such that they will not replace another app on the A7 that's listed as a partner app (see this documentation ). What do you mean by "use memory"? I was under the impression that separate applications have their own virtual memory address space to enforce process isolation. Additionally, an application cannot share mutable flash storage with another app.

alexwulff -> Read/write (mutable) storage, which persists when a device reboots. For information about mutable storage, see Using storage on Azure Sphere . This is one type of sharable memory. Clem
