So you can enable use of an MQTT server; either your own, or the Meshtastic project one, to enable long-range messaging over the net. So - if I were building out a project for ENCRYPTED ONLY, messages to only people that were within my threat model, I'd put up enough nodes to cover the area needed... and/or, join other nodes in some larger network like a city (Portland) or rural area that I were interested in communicating with. (Willits/Ukiah, CA - Wildfire comms... in 2019 there was a huge wildfire there and they lost cellular comms; they now cover the 50mi area w/ Meshtastic and over 500 nodes.) Og> It is interesting that encryption is supported and a HAM Og> license is not required. Yea; in the U.S., Meshtastic happens on the 918 band - and it does offer a lot of cool features w/o the need to be... licensed. Its just not that long-range, which is why it can get around those issues IMO - when technology surpasses yesteryear regulations, it inspires ... new regulations? UGH.

It is - just that you have to tether the Heltec v3, LilyGo T-Beam and other devices to an Android or iPhone device - its THAT device that I don't trust. And while its just an app that runs on it, I don't trust that Apple or Android has our best interests at heart; so I prefer a standalone unit that doesn't have to rely on a phone to do the business end stuff....

It is; I'm going to pair the LilyGo T-Deck w/ an antenna, a GPS module, battery and a nice case to hold it all together - for a complete standalone node.... or 3.
