Hi RIOT users and developers, Is there an easy way to combine a sock instance listening for incoming UDP packets, with some timed events without making two separate threads? I have a process which needs to respond to incoming data over UDP, but also perform some other tasks every x seconds. Are there any hooks for using gnrc_sock_udp as part of an event loop? Perhaps using thread_flags or some way of interrupting a blocking call to sock_udp_recv (to make it return -EAGAIN) Using sock_udp_recv with a timeout value of 0 lets the program poll for incoming data, but without any thread flags or callbacks it will take too much CPU budget to keep polling the recv function while servicing other parts of the system. I have used https://github.com/RIOT-OS/Tutorials/tree/master/task-06 as a starting point for my application but currently I am stuck on implementing these timed events.
Best regards, Joakim
