The android apps on both my android devices would run the loco with loco-firmware 3.21. But my apps on my android (4.4.4) phone would not work with loco-firmware 3.45. But, finally some good news, the BlueRail app on my android (5.1.1) tablet works with loco-firmware 3.45. So I finally have a working android/3.45 setup, and can "play".
