Connect to two bluetooth devices

[CB925]

Hi all. I found instructions about how you can use Pybricks to connect to the duplo train. It works, however when I connect to the train it's not possible to connect to the lego remote control. And if I connect to the remote first, it's not possible to connect to the train later. I get an error message about the system being busy on the second connection attempt. Can the hub only connect to one bluetooth device at the same time, or something else wrong? I'm using the technic hub.

Can the hub only connect to one bluetooth device at the same time

Yes, this is correct. From the Technic Hub's point of view, connecting to the Duplo Train is very similar to connecting to the Remote, and it can do only one of those. (After all, it also still connects to your computer, so the connectivity all adds up and there is a limit.)

Just as an alternate idea, could you creatively make the Technic Hub itself "be" the remote, by attaching handles or sensors to it?
