Bumper backup reflex cannot be disabled

[halimimaha]

Robot Model
Turtlebot4 Standard

ROS distro
Humble

Networking Configuration
Simple Discovery

OS
Ubuntu 22.04

Built from source or installed?
Installed

Actual behaviour
I followed this tutorial: https://iroboteducation.github.io/create3_docs/api/reflexes/ but when I send the command to disable the bumber it doesn't work, the bumber is still activate, any suggestions ?

To Reproduce
i sent this command :

ros2 param set /robot1/motion_control reflexes.REFLEX_BUMP false

i tied also to add "reflexes.REFLEX_BUMP: false" in the end of this script in web server of create 3 :

motion_control:
ros__parameters:
# safety_override options are
# "none" - standard safety profile, robot cannot backup more than an inch because of lack of cliff protection in rear, max speed 0.306m/s
# "backup_only" - allow backup without cliff safety, but keep cliff safety forward and max speed at 0.306m/s
# "full" - no cliff safety, robot will ignore cliffs and set max speed to 0.46m/s
safety_override: "none"
reflexes.REFLEX_BUMP: "false"

Hi,
Which version of the create 3 firmware are you using?

What's the output of this command?

ros2 param set /robot1/motion_control reflexes.REFLEX_BUMP false

Can you confirm that the parameter is disabled by running

ros2 param get /robot1/motion_control reflexes.REFLEX_BUMP

Can you try to disable all reflexes

ros2 param set /robot1/motion_control reflexes_enabled false

Lastly, your yaml syntax in the webserver seems wrong.
You are passing the argument as a string rather than a boolean. It should be:

reflexes.REFLEX_BUMP: False
