Here is a good place to start to learn the tech, I built an emergency Mesh network for CERT related activities based on that, I suspect there will be similarities:

So? Gater? I’ve got the thing assembled and flashed with the latest Meshtastic version.

When can we expect the rest of the videos or some kind of instructions for the next steps?

Later today I’m gonna try to download the Android Meshtastic app and play with it, but we’ll need some more info on how to set it up and the the badges all talking to each other at DC31.

Thanks.
