Connection with Groot2: connect once then lose connection

[ipa-rwu]

I am running BT in loops and want to monitoring via Groot2. First I try as an example [here] https://github.com/BehaviorTree/BehaviorTree.CPP/blob/78bdb97b122d685d0b3b8c89bffa402f97998748/examples/generate_log.cpp#L31 Then I found it connected once, then lose connection.

I think it needs to use "flush()" function in the loop https://github.com/BehaviorTree/BehaviorTree.CPP/blob/78bdb97b122d685d0b3b8c89bffa402f97998748/include/behaviortree_cpp/loggers/groot2_publisher.h#L55 But it is defined under private.

As you can see here, this is not your problem:

https://github.com/BehaviorTree/BehaviorTree.CPP/blob/master/src/loggers/groot2_publisher.cpp#L228-L231

Then I found it connected once, then lose connection.

It must be something else. Can you provide more details? I am assuming that you are using Groot2. Could it be a connection problem?
