Newbe error question: #error No forward link or gateway feature activated

[A Former User]

Hi,

I'm very new to this. Trying to construct the dimmable mirror. I added the libraries and tried to verify the code. I did change #include <MySensor.h> to #include <MySensors.h> because an error message said couldn't find MySensor. Now it get this error message and not sure what means:

C:\Users\Documents\Arduino\libraries\MySensors-master/MySensors.h:287:4: error: #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.

#error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.

Thanks

Did you use the following example?

No, I used https://forum.mysensors.org/topic/936/backlit-dimmable-led-mirror-with-motion-sensor/2

I tried the code from that example and had no issues.

Sorry, had no issues when I tried https://www.mysensors.org/build/dimmer

is for MySensors 1.x. It won't work with 2.x unless it is converted.

Where do I go to find out what need to be done and how to convert it?

Thanks

Thanks, got it working. There still is a error message:

In function 'void loop()':

warning: comparison is always false due to limited range of data type [-Wtype-limits]

     fadeLevel = fadeLevel < 0 ? 0 : fadeLevel;

Not to worry??

Nothing to worry about.
