RE: One-to-many event handling for Zephyr with data transfer?

Zbus is part of Zephyr now. You can use Zephyr's main (unstable) version to test Zbus in your solution. I would encourage you to take a look at the samples. If you have questions, please let me know. Reach out at Zephyr's Discord discordapp.com/.../1042530682011926631.

RE: One-to-many event handling for Zephyr with data transfer?

I asked a developer internally that's been working with the AEM and got some insight.

Regarding the question about needing to copy data when there is a lot of consumers (since the data will be lost after it's delivered to all listeners), this will be the case in most similar systems, as amount of memory is limited and you can't hold data indefinitely.

AEM is asynchronous (messages (events) are delivered in strictly defined order), and is used to simplify applications by reducing the amount of threads. It seems like you're looking for a system to transfer data between multiple threads. In that case Zbus might be a better option: https://github.com/zephyrproject-rtos/zephyr/issues/45910

Best regards,
