Error 4 when reading TDMS file block-wise

[_Y_]

I try to read data from TDMS file in portions (blocks). Seems TDMS Read Function has corresponding inputs. However, only first block is read. Attempt to read second block launches error 4 “End of file encountered”.

This is simple code reproducing the error. The VI and TDMS file are attached. The file has I16 data format and contains 1024 data points.

What is wrong?

Thank you

You need to wire in your group and channel name to your read function, just like you did for your Get Properties function.

Yes, it works now. So simple.

I wonder why first block is read even without channel and group names?
