SR04 ultrasonic sonar issue

The issue
I am using ESP32S3, and kept getting when trying to get sonar readings. I have tried both SR04 and AJ-SR04M sonar boards and have similar results:
- Sonar heads are sending signals (LED blinks on SR04M, and I can hear both heads sending signals from noise cancelling headphone)
- Both will get error: Error 513: Ping timeout (no device found)
Can anyone shed some light on this?
Thanks
