Priority of the OSC sender task?

Ward

I have a bunch of AuxTasks doing stuff in the background. From a non-RT task I'm sending binary blobs to mirror a display on LED matrices connected to a Pi (

At Superbooth I noticed the OSC messages would sometimes not arrive for several seconds while a heavy task was running. Once the heavy task was done the backlog of messages would all be sent at once.

I looked around the codebase and found the OscSender uses an AuxTaskNonRt which seems to have a default priority of 0?

It seems the AuxTaskNonRT is only used by OSCSender and WSServer? Can I increase/set the priority? Or can I perhaps set my own tasks with a priority below 0 to get them to yield to the osc sender task?

This allows you to set priority: https://github.com/BelaPlatform/Bela/commit/175dbd0af314de850226890d0503a84b00b8469c

Even setting it to 1 (i.e.: SCHED_FIFO, priority 1) will boost it a fair bit, above anything the OS would normally do. If you have other concurrent SCHED_FIFO (aka "real-time", from Linux's point of view) threads (e.g.: MIDI, I2C), you can balance their relative priority accordingly.
