Hi everyone,

Is there a way to have the same behavior as the xQueueReceive function implemented in FreeRTOS with a timeout that can be specified in order to not block our task infinitly. I have taken a look msg.h interface, but i can’t find something that looks like what i want? Am i missing something ?

Thank you very much.

Salut,

A good question that has been answered in our documentation already:

https://riot-os.org/api/group__core__msg.html

Timing & messages

Timing out the reception of a message or sending messages at a certain time is out of scope for the basic IPC provided by the kernel. See the xtimer module on information for these functionalities.
