Hello Yajai,
The example program will use the default value for timeout, 10 seconds. To change this, you will have to set the Stream.Timeout value. I inserted this function into the example and set it equal to -1, and the program will wait indefinitely for the trigger signal without timing out. Please see the attached image to how this was implemented.
I hope this help. Let me know if you have any further questions.
Regards,
Sean C.
