How to send data to a Boron from multiple Xenons via Mesh?

Firmware
1

It is very exciting to be finally working with the Boron and Xenon.

Where can I find examples regarding sending data back and forth between multiple Xenons (in a mesh) and a Boron?

When data is only sent to the Boron but not to the cloud, does this incur any data charges?

Thanks in advance for the community’s help.

Have you considered checking the docs?

Thank you @Moors7 for the link.

Before posting, I did. However, doing a Google search did not return any useful links as I was not searching for “publish”.
