Hello everyone, I’m new here.
I have a question because i’m in front of a problem since a week and I really can’t resolve it alone.
So:
I have 5 Arduino, one is setted in Coordinator API and others in End Device API mode.
What I want is that every end devices could communicate with the coordinator, and the coordinator could send them an answer.
I tried a lot of code samples which I’ve found on internet but it doesn’t work at all.
I really need your help and hope that someone will be able to answer me.
(ps: Sorry for my english level, it’s not my mother tongue)
Thank’s in advance!
