Is it the steering motor is only works on C+ Lmotor? My steering test on C+ XLmotor didnt work. The calibration of C+ Lmotor can only be done on Lego official app.
Look very promising. I have tested the apps and the basic control is working. How about an ability to change background wallpaper, background colour & renaming the button. Integration of internal gyro sensor data would be an awsome addition.
