…e to switch state and notify serial outgoing thread. Added self.serial_event.wait() after checking if the queue is not empty so we can notify the outgoing thread. The workflow goes as follows: serial_rx_thread receives a message (ACK/NAK) -> set a flag and notify the state machine -> state machine change state and notify the outgoing thread -> outgoing thread process the state change

…e. It should go serial handler incoming thread -> state machine -> serial handler outgoing thread -> state machine. The order of operation is shown here when running it on debug view. However, there is a race condition when the serial handler incoming thread and the serial handler outgoing thread are updating the serial event queue at the same time, causing the state machine to only see the event in the queue before the serial handler outgoing thread gets a chance to update the queue
