My understanding is that the taks calling tx_queue_receive should stay in suspend mode until it receives Msg because the TX_WAIT_FOREVER is set. However, in this case, I received TX_QUEUE_EMPTY: (0x0A) which is defined as below. It's hard to corelate my assumption and the explanation below, can I get some hlep. :)
TX_QUEUE_EMPTY: (0x0A) Service was unable to retrieve a message because the queue was empty for the duration of the specified time to wait.

Are you sending anything to the queue?

Frank, Zacharias 0 Reputation points2023-09-19T11:42:36.5733333+00:00 I have the same problem. As far as I can tell, the global variable _tx_thread_preempt_disable is 1 as I enter the QueueReceive function, which is why it immediately goes to TX_QUEUE_EMPTY.
