I am a newbie with Cayenne but not in IT. But it seems that I am to stupid to get a simple project running.
I am using an Arduino Meg 2560 which is connected via USB. The first Connection (with CAYENNE_OUT_DEFAULT()) was working and I saw a value.
But now I want to reproduce the Luminosity example. The connection is OK because I can see the Arduino colored under my devices. I add the slider to the desktop but I can not Change something. I tried it via the smartphone app and there I will get the Feedback “Can not connect the remote device.”
I tried different ways. Firts with custom widget. Next with Actuators -> lights -> Luminosity. Third via Actuators -> Generic -> PWM Output. Nothing works. So I can not write the LED value back to the device.
What I am doing wrong? What is the trick?
