How to multi device connect?

I used Astra and Astra mini-S camera.

I want to connect several cameras at the same time and get stream.
In SDK source, set to device/default to check the setting of the device. But what else do you need to do to connect the another device?

I’ve find an example in the latest sdk.
Thank you.

You found an example in the SDK where you can connect multiple sensors to the same PC? I thought the SDK only allowed 1 sensor connected at the same time on a PC. Where did you find the example?
