Just got my hands on the 42100 and discovered my note3 isnt combatible with the offical app so luckily this one saved the day! All is working ok however im having issues with servo control. When im in the servo config page the angle set and calibration work just fine but when i tried to use it with a ps4 controller the motors will just turn on and then become unresponsive. If i move the joysticks extremely slowly im able to get the motor to move over its servo range but anything more than that and ill get the runaway issue. Is there any fix for this or i'm doing something wrong perhaps? Also noticing the motors drive past the correct point then correct themselves, is this something inherrent with the motors themselves or a BC2 thing? not sure how the operation is with the offical app.
