Check connection function in Sync

[ingdesarr1]

Good afternoon. I want to use the function check_connection in the asyncua.sync to check if my client is connected, but reviewing the documentation I can't find any information and it seems that the function only returns None. Is there a way to use this function without having to change everything to async? since I will have to change my entire application and it is a lot of work. Thanks

Does check_connection throws an exception, it does not return a bool.

Not work. I try this:

I'm not connected to any opc-ua, and print this:

check_connection only works if you have already connected to a server.

Today, I try to use the function the server connected and the function return None. Is any other way to check the connection?

This function is to check if the connection is alive and not broken. If the connection is broken, the underlying exception is thrown.

If you want to know if you already connected, just add a bool and set it to true if you connected to the server.
