Using Asyncua and pyserial

[ingdesarr1]

Good morning.

I am developing an application to control a process through opc-ua. I need to read multiple weight controllers through serial ports. Currently, I make the connection and read the weight through threads, but if I am connected and reading, sometimes an error is generated in the opc-ua server connection. For reading the variables by opc-ua, I am making the subscription through the class and the datachange_notification.
I would like to know what would be the best way to work with asyncua and pyserial to prevent the reading of data from both processes from being hindered or generating errors between them.

Thanks
