Hi @mohammadpoorkhalili,

This is actually a normal behavior. Indeed, after timeout connection, the device gets static address. You might then change the application behavior to use only dynamic address or to use only static address or to switch differently from dynamic to static.

As this issue is not valid, please allow me then to close this thread.

With regards,
