Optimize ESP32 BMI Timing

I have an ESP32 project with a TFT display that measures BMI (Body Mass Index).
The code is working, but there’s a timing issue during the measurement phase.

Currently, when a user steps on the BMI machine, the display shows “Measuring…” — this message stays on the screen for around 2 minutes 10 seconds, even though the delay in the code is set to 2 seconds.

The total process (from “Measuring…” to displaying the result) should ideally complete in 10 seconds, but it’s taking far longer.

I need a freelancer to:

Debug and identify the cause of this extra delay.

Fix the timing issue so that the measurement and display update happen within the correct time frame (around 10 seconds).

(Optional) Suggest or implement code optimizations for smoother performance.
