How to Get Value of 'TILT-ANGLE' in Gyro Sensor ?

Hello! I’m Testing to Get Value from ‘TILT-ANGLE’ mode of Gyro Sensor. But The Following Error Occurs : (‘TILT-RATE’ Mode Is No Problem And Date Code of Sensor Is ‘N6’)

-Source Code-

#!/usr/bin/env python3
from ev3dev2.sensor import INPUT_1
from ev3dev2.sensor.lego import GyroSensor
from time import sleep
import sys

gy = GyroSensor(INPUT_1)
sleep(0.5)
while True:
    print(gy.tilt_angle, file=sys.stderr)
    #print(gy.tilt_rate, file=sys.stderr)
    sleep(0.5)

---

-Error code-

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/ev3dev2/__init__.py", line 261, in _set_attribute
    attribute.write(value)
OSError: [Errno 22] Invalid argument

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/robot/start/01_gyro.py", line 16, in <module>
    print(int(gy.tilt_angle), file=sys.stderr)

    self._ensure_mode(self.MODE_TILT_ANG)

    self.mode = mode
  File "/usr/lib/python3/dist-packages/ev3dev2/sensor/__init__.py", line 182, in mode
    self._mode = self.set_attr_string(self._mode, 'mode', value)
  File "/usr/lib/python3/dist-packages/ev3dev2/__init__.py", line 321, in set_attr_string
    return self._set_attribute(attribute, name, value)

    raise exception from cause

Can Someone Fix This Problem by Modifying the Code? Thank You !

At the beginning of your program (after the import statements), you can put…

GyroSensor.MODE_TILT_ANG = 'TILT-ANG'

Thank You for Your Reply. Your Advice Was Right.

gy.modes ['GYRO-ANG', 'GYRO-RATE', 'GYRO-FAS', 'GYRO-G&A', 'GYRO-CAL', 'TILT-RATE', 'TILT-ANG']

Mode Name is ‘TILT-ANG’.

But It was defined In GyroSensor class like Below.

MODE_TILT_ANG = 'TILT-ANGLE' MODE_TILT_RATE = 'TILT-RATE' `

so, I Could Get a Value of ‘Tilt_angle’ by Modifying my Code like Below.

gy._ensure_mode('TILT-ANG')
while True:
    
    print(gy.value(0), file=sys.stderr)
    #print(gy.tilt_angle, file=sys.stderr)
    #print(gy.tilt_rate, file=sys.stderr)
    sleep(0.5)

Nevertheless, How Can I Modify the GyroSensor class Variable ?
