I am trying to connect a Duplo train to the iOS version of BrickController2, ver 2.6, but the app will cannot find the hub. I have two of the duplo trains, neither is connecting. I was able to successfully connect the 88009 hub that comes with the batmobile, and also an Xbox One controller.
At the end of this video you see the app controlling a duplo train, so it seems it should work.
Should version 2.6 connect to the duplo train, hub no. 5?
Two other details. Both duplo trains successfully connected to the lego duplo app, and I could control them with it, so I know they are working.
And I am running the BrickController2 app on an iPhone8 plus, iOS version 13.3.1.
