Maybe they just need to read about real time scheduling to assign an approriate priority or do the execution in a thread with appropriate priority.
If there is a receive buffer execution should be triggered no later than half full and must be emptied before it may be filled. With time known to make buffer half full maximum periodicity is known and an appropriate priority could be assigned. > It only sort of does.
