Is it possible to use xQueueOverwrite in one task and read the same queue in another task. Or is there the possibility that the reading of the queue will be interrupted by the xQueOverwrite in the other task. So the data read from the queue can be corrupt. Or is this handled by the queue mechanism that the queue can only be overwritten when the queue is not read somewhere. Thanx in advance Frank

All FreeRTOS communication methods are thread safe. Queues can have any number of readers and any number of writers.
