Hi, Steven
Thank you for your advice.
Root cause is the baud rate wrong selection.
best regards.

Hi, Steven,
I found that i selected wrong baud rate . Correct baud rate is 115200.
I managed to read the ASCII input data.
I found new problem.
My program can read incoming data (data from R-Visa) but just starting period only.
Do you know why ?
Attached images files for your reference.

Hi, Steven,
The data is from Bluetooth receiver.
Data format is ASCII.
best regards.

Still no VI, just images: how should we edit/debug them with LabVIEW?
Replace the BytesAtPort by a numeric constant, and set its value to 999.
Also remove the "Wait before read" sequence frame completely with its content!

GerdW already gave you good advice:

Here's a cleaned up version that should work.
