I have the library v0.3.0 and the new update for iOS, I use arduino UNO connected using USB. My problem is that the communication between the mobile and arduino is very slow, which results in problems when using the joystick or the slider. I don’t now if this happen to more people, and if it does, will it be fixed soon?
What is your ping between hardware and server and between App and server?
I am using V1 for the joystick and D9 for the servo. I am doing the same than in the servo example.
As I said - please check your ping between hardware and blynk server. If it is slow enough - please install local server. It is very easy.
