Stuck on "waiting for behaviour"

[tim-fan]

Hi there, I'm trying to run through the basic tutorials, but am not able to get a behaviour to run. It appears to be stuck waiting for confirmation from onboard behaviour.

Not sure if this is a bug or if I've missed something in the setup.

I'm using bionic/melodic

How I set it up:

mkdir -p catkin_ws/src
cd catkin_ws/src
git clone https://github.com/FlexBE/flexbe_app.git
cd ..
rosdep install --from-paths src/ --ignore-src
source /opt/ros/melodic/setup.bash
catkin build
source devel/setup.bash
cd src
rosrun flexbe_widget create_repo test_repo
cd ..
catkin build
source devel/setup.bash
roslaunch flexbe_app flexbe_full.launch

When the app opens I select "Load Behaviour" then "Example Behaviour". Then I select "Runtime Control" and click "Start Execution". The app shows the screen from the following screenshot, and never transitions past this state ('waiting for confirmation from onboard behaviour'). I waited up to two minutes, but still the screen did not update.

The full terminal output from roslaunch is:

Any ideas on how to get this behaviour to execute?

[zerolatnc]

I have the same issue.

Can the two of you check which version of the flexbe_onboard/widget packages you are using?

Running the behavior from the create_repo command works fine for me on 16.04 with the current develop branches.

[tim-fan]

I got those packages from apt (following instructions from https://philserver.bplaced.net/fbe/download.php)

This gives me the following versions:

$ rosversion flexbe_widget
1.2.5
$ rosversion flexbe_onboard
1.2.5

[tim-fan]

Follow up, I've confirmed if I build everything from source then the state machine runs (does not get stuck waiting for behaviour).

To be specific, I cloned flexbe_behavior_engine into my source space:
git clone https://github.com/team-vigir/flexbe_behavior_engine.git
Then rebuilt, then it all worked.

So it looks like the issue is that the released packages for melodic are not compatible with the master branch of https://github.com/FlexBE/flexbe_app.git

Closing this based on lack of recent comments. If you see issue on consistent Noetic or ros2-devel/humble branches, then please re-open or file a new issue

Unfortunately I have encoutered a similar issue while running flexbe on noetic. I have both flexbe_app and flexbe_behaviour_engine cloned into the src folder in my catkin workspace and checked out on the noetic branch. Below is the output of runnning the app:

When I click "Check Behavior" the terminal gets stuck on "Performing behavior checks"

Clicking on "Save Behavior" does nothing. Even though the configuration screen suggests that there is a connection to the ROS master:

it is contradicted in the "Runtime Control" screen:

Most confusingly these issues only came up after around 1 hour of using flexbe after I was able to develop my behavior partially. I would really appreciate help with the issue.

[dcconner]

Have you tried pressing the "Connect" button on the Runtime control screen.

Also, verify that all of the ROS nodes are running: the mirror, be_launcher widget, and onboard are still running.
