I am wondering about what the difference in when and how to access a component after a product connected.

• One can either wait untilDJISDKManagerDelegate.productConnected and productChanged get called and then access the component
  

or wait for

• DJISDKManagerDelegate.componentConnectedWithKey gets called, check for the key and then get the component from the product.
  

Can I safely assume, that when a product connected, all its components are connected as well?

Are there any advantages or disadvantages of any of the both methods above? Maybe different use cases?

Have also asked this question on StackOverflow: https://stackoverflow.com/q/65806875/1065468

Maybe you can use methods componentConnectedWithKey:andIndex, componentDisconnectedWithKey:andIndex to listen the compoment status.

Yes, thank you, this is what I do. I use this method and check the key to determine which component changed.

But I was wondering if by the time the product connected all the components also have connected or does it take longer for them somehow to get connected?

Got a very helpful reply on SO which confirms my assumption that components might connect at a later point after product connection and not immediately after.
