Best way to send data between MDKs?



I’d like to have one or two MDKs with sensors able to send data back to a third MDK which could send the data to my computer via the putty terminal. Is there a simple way to do this?

I’ve tried playing around with the thread examples but I taught it was probably too complex for what I was trying to achieve. I also got the Mesh light switch example uploaded to three MDKs but I’m not getting any LEDs switching on or off.

Is there any example where I could push the user button on one MDK and have an LED light up on a second MDK?
