URM07-UART always getting 0cm
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I can't read the distance with the URM07-UART. I'm using a NodeMCU ESP8266 connected as follows :
NodeMCU RX PIN -> URM07 TX Pin
NodeMCU TX PIN -> URM07 RX Pin
I am using the exact code sampled here under "Read Temperature Value via Arduino (Single)" : https://www.dfrobot.com/wiki/index.php/ ... U:_SEN0153
Here is a picture :

The code uploads fine but the console output always writes 0cm.
Thank you
