Manage multiple Bluetooth devices simultaneously

MIT App Inventor Help
1

Hi,

can I manage multiple bluetooth devices simultaneously with the Bluetooth Server or Client component?

2

You can manage multiple devices yes -simultaneously? depends.

What exactly you need to do with them (send/receive data?) and how often if the processes are to be near simultaneous.

3

yes, but as far as I know for each connection you need another server and client component

Yes, but it's very repetitive. If you store all the Button components in a list, you can set each of their text values with a for loop.

Given from what you said in post #5, they seemed like Buttons. It's fine, you can just change the Set Any Button.Text block to Set Any Label.Text.

Sorry for the confusion.

It's an Any Component block, which allows you to modify the parameters of a variable component.
