Need Help with Fingerprint Scanner Interface on ESP32

Hi everyone,

I hope you're doing well. I'm currently working on a project where I need to interface a fingerprint scanner with an ESP32 microcontroller. I'm encountering an issue when trying to run an example from the "DFRobot_ID809.h" library, specifically for fingerprint registration. The error message I'm getting is "communication with device failed, please check connection."

Here are some details about my setup:
- As per the documentation, I have successfully connected the fingerprint scanner to the ESP32 using wiring.
- I have successfully configured the baud rates.
- The power supply appears to be reliable.

I'm not sure what's causing this communication error. Has anyone else encountered a similar problem, or can you provide some guidance on how to troubleshoot and resolve this issue?

Any help or advice would be greatly appreciated. Thanks in advance!
