Modbus Not Responding Issue on ESP32 S3 T-Vending

[Hari Prasath]

Hello,

I'm currently working on an ESP32-S3-based T-vending project where I'm using Modbus communication to control various devices. However, I'm facing an issue where the Modbus communication seems to be unreliable, and I'm not receiving responses as expected. I've attached a screenshot of whatever data was papullated in the communication port.

The problem I'm encountering:
==>The ESP32 does not respond consistently to Modbus requests.

What I've already tried:
==> Checked hardware connections and wiring.
==> Confirmed the correct Modbus address is set on the ESP32 s3

Regards,
Hari Prasath
