hello, I am trying to use the Grove Ultrasonic Ranger (v2.0), with the GrovePi+ hat on a raspberrypi 3b+. The device is detected when using ‘sudo i2cdetect -y 1’, but, when I run the program, nothing happens. I do not get an error, nor does anything print. It is as if the program is running, but stuck, and not giving an error. I am using the default code provided. I have used different ports, and am getting the same thing. Even when I run the program without changing the port that it is connected to, nothing happens. Below is the code I am using, which is the code given on seeedstudio.
GrovePi + Grove Ultrasonic Ranger
from grovepi import *
Connect the Grove Ultrasonic Ranger to digital port D4
ultrasonic_ranger = 4
# Read distance value from Ultrasonic
except TypeError: print "Error" except IOError: print "Error"
