The PC connects. It is the H9 app that says it cannot find the device. Regarding the iPad would that be true even if the iPad is in a different room?

What does H9 Control say? Can you see "H9 Pedal" as a MIDI device in H9 Control?

It depends how far your room is from you. If you check your iPad's Bluetooth setting and make sure H9 is not connected there, it should be good.
