I have checked existing issues, README.md and ESP32 Forum
- [X] I confirm I have checked existing issues, online documentation and Troubleshooting guide.
@vgegok It is not clear to me what are you trying to say.
Could you provide more information about the problem? Is there an issue with an example or with the driver itself?
