You need a command line to install it on unsupported hardware.

The application is freemium, written by one of the devs from the Reticulum project. The core is open source so anyone can write a client for it. We’re in the early days so I imagine more clients will pop up.

Oh, I should say firmware support is very early. There’s only a handful of supported devices, but contributions are coming in fast. My friend and I worked on the Lilygo T3, I know there’s work being done in the T3S3 and other devices. .

Take a look at meshcore. It’s very promising. About 4 weeks old. There’s even a dev from reticulum working on it!
