get_compass() always returns 0

[b-per]

Hi,

using the code below, I see that the Sense Hat on my RPi2 is continuously returning 0. My Pi is running OSMC, a kodi distribution based on Debian Jessie.

from sense_hat import SenseHat

sense = SenseHat()
sense.set_rotation(0)
sense.clear()

while True:
    dir = sense.get_compass()
    print(dir)

I installed the packages python-sense-hat and python3-sense-hat but not sense-hat as according to this thread it will mess with OSMC: https://discourse.osmc.tv/t/sense-hat-how-to/8929/5

I tried to run some scripts to use the LEDs of the Sense Hat and it is working.

when i ran that code on raspbian it worked. annd returned numbers consistently correct.

I've had some troubles with my sense hat's magnetometer, but I did get consistent results after I ran the calibration steps.

I installed the packet librtimulib-utils to get the program RTIMULibCal but at the end of the installation, the folder RTEllipsoidFit contains only the following files:

ellipsoid_fit.m  
mag_cal.m  
mag_fit_display.m  
RTEllipsoidFit.m

So I downloaded the files from here https://github.com/RPi-Distro/RTIMULib and compiled RTIMULibCal. But then a new error appears:

$:~/xxx/RTIMULib/Linux/RTIMULibCal/Output$ sudo ./RTIMULibCal
RTIMULibCal - using RTIMULib.ini
Settings file RTIMULib.ini loaded
Failed to open I2C bus 1

If it is useful, the result of sudo i2cdetect -y 1 is the following Error: Could not open file/dev/i2c-1' or /dev/i2c/1': No such file or directory

After a bit of troubleshooting I found where the issue comes from. I had to add the value i2c-devto my /etc/modules file and restart the RPi. Now I just need to calibrate the sensor but at least it is returning some values. Thanks for the help, I am closing the issue.
