A01NYUB ultrasonic distance sensor with firebeetle ESP32
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
Hello
I'm trying to use the A01NYUB ultrasonic distance sensor on the firebeetle ESP32. I've connected the VCC to 3.3V and the GND pin to GND of the firebeetle. Further I left the RX pin floating and have connected the TX pin to a digital IO.
When I try to connect over the hardware serial (9600 baud, 8 databits, 1 stopbit, no parity) I can read data from the sensor and the blue led on the back of the sensor is blinking but I can't see any change in the RX data when I change the distance of the object in front of the sensor.
Has anyone ever used this sensor on an ESP board?
