Receiving multiple messages.

Hi there, in my project I use nrf52840 and coap server/client relationship so the question is can I receive multiple messages at the same time on the server?  I found some information about it https://devzone.nordicsemi.com/f/nordic-q-a/35794/handling-multiple-messages-in-mesh but this explanation for Bluetooth but I use OpenThread.

Hi,

No, you can't receive multiple messages at the same time. If you send multiple messages to the same target, then the messages will be handled on that target in the order that they arrive. They should't arrive at the same time, but if that happens none will be received as there will be a collision. That is why there are mechanisms like "listen before talk" used.

so, I need to implement this mechanism or is it built-in?
