Message queue delivery address or value?

The message queue delivery method is value transmission in freertos.
In the case of how much data, Need to change the way to pass the address? 4kB? or 8kB?
Is there any guidance from the official?
thx.

It’s up to you. There is no general rule because it depends on your application.

Your question is not very clear, but you should be able to send any address.
