I have already written influxDB, I just want to add a function to dynamically display data, similar to data backtracking. I'm here to solve problems, not add to them. Why do you have so many questions?

You said that wanted to read data from a file and write it to influx. Now you say that you have already written it to influx. Why do you want to write it again.

Because I need to understand your problem in order to help you.

I don't know, but I am guessing:
The data gets into your computer (via BLE) and into the file, all before it hits either Node-red or Influx.
Then you use Node-red to read the file and write to Influx. The timing problem is here.
And the intention presumably is to display the data from Influx.
Maybe a diagram showing the data flow would help me understand.
Also a small sample of the data arriving via Bluetooth, the file contents and the database structure. A screen capture of your flow might help too.

We are all here for the same thing then 🙂
