Greetings,
I'm trying to send packets using a star topology in lrwpan without internet. from 3 devices to a single device in the MAC layer without the need on internet nor IPs.
All of the examples that I saw require an IP. How can I do it without that?
Also, How can I send multiple packets from all devices to one device. I'm having a hard time specifying the source of the packet. (code is attached)
