Garmin Lidar-Lite v4: getting "Measurement failure" message

Sensors Distance
1

I am using the Garmin Lidar-Lite v4 on a Raspberry Pi 4 running Rasbian.

I ran both

pip3 install adafruit-circuitpython-lidarlite

and

sudo pip3 install adafruit-circuitpython-lidarlite

Using “sudo i2cdetect -y 1”, the address of ‘62’ is detected, which matches the Lidar-Lite v4

From https://pypi.org/project/adafruit-circu … lidarlite/

I was running the “Usage Example”

import time

import board

import busio

import adafruit_lidarlite

Create library object using our Bus I2C port

i2c = busio.I2C(board.SCL, board.SDA)

Default configuration, with only i2c wires

sensor = adafruit_lidarlite.LIDARLite(i2c)

while True:

try:

We print tuples so you can plot with Mu Plotter

print((sensor.distance,))

except RuntimeError as e:

If we get a reading error, just print it and keep truckin’

print(e)

time.sleep(0.01) # you can remove this for ultra-fast measurements!

but I’m getting “Measurement failure” message

My Raspbian version is

Thanks for reaching out to us on this.

While we don’t provide coding support, it looks like there might be an unneeded comma @:

print((sensor.distance,))

Could be wrong, but perhaps try deleting that and running again.

Hope this helps, and happy sparking!
