I have a Matrix ICR50 which connects to other apps but not this one. It says there is an error and to press the stop button for 3 seconds. There is no such stop button. Tapping try again repeats the error until the Bluetooth module turns off and the error message changes to Not Found. The display on my iPad mini is always in portrait mode, does not change to landscape so not suitable. Other apps do change orientation. I am abandoning this app even though Matrix recommended it, and looking elsewhere. Test BT with fitDisplay. I’ll try Kinomap next, also recommended by Matrix.
