I have a task waiting indefinitely for a task notification
ulTaskNotifyTake( pdTRUE, portMAX_DELAY );
when another task performs a vTaskResume() to the waiting task. Even though an infinite delay was specified the ulTaskNotifyTake returns when the vTaskResume is executed. This does not happen if instead using a semaphore because my understanding is that the resumed task is moved to the ready list but when it goes to run it the timeout is checked which hasn’t expired and goes back to waiting. But with the task notification it resumes even though the timeout hasn’t expired. The value returned by ulTaskNotifyTake is pdFALSE so I was able to wrap it with a loop
while(!ulTaskNotifyTake( pdTRUE, portMAX_DELAY )) ;
but I don’t need to do that for the semaphore and I expected the behavior to be similar to the semaphore. So is this the proper/expected behavior for task notifications or is this a bug?
