Is there a way to know if the connection is still active?

I tried with send_hello but when I send that message, the connection drops after a while. (wondering why)

Is there any way? will make sense to have that functionality?

the safest is to read the attribute value of a node

Note that sending a HELLO message is only allowed during the connection phase:
