Hi. I purchased 3 Yamaha bt-01 in order to put them on different pedals and control them all from the Ribn iPadOs App. I've 2 Bt01 mounted on two indipendent pedals (that have midi 5pin ports) and another bt-01 on a midibox that is connected to other 2 pedals. I've set all pedals on different channels, but I can't figure out why if I connect only one Bt-01 is working flawlessy, but if I manage to connect all three bt01 they don't receive any signal from the app. I'm also sure I've connected all three bt-01 with the app and enabled them in the MIDI app menu. Is there a way I can get to work the connection or is there some limitation due to the fact the app have to connect and send the same messages to all three bt-01s??

Thanks a lot in advance
