Is it possible to have two processes communicate in ARM Qemu?
Yie
Hi, Is there an inter-process communication functionality on Zephyr running on Linux for Qemu? I have an application on Zephyr that gets data from an external source. However, since I do not have the actual device, I will be emulating this on Qemu. So I will have 2 applications, one solely for generating the output. However, how can these two applications communicate? I know this can be done in C using named pipes. Is it possible to do that with Zephyr as well? Any help would be much appreciated. Thanks. Cheers, Yie

Hi Andrei, Thanks for your reply. Are there any other QEMU_EXTRA_FLAGS that allows applications to communicate with one another without using bluetooth? Like named pipes in C? Cheers.
