Yeah, it does require specific devices. However, the upside to it is that it can go way farther than Bluetooth.
I had my node here in my window and was talking with a router 200 feet on a tower from a couple of miles away. And there's another guy in my area who had his node up on a 30 foot flagpole and was talking to the router from 17 and a half miles away. Bluetooth just cannot do that.
About the maximum you're going to get with a 7-hop Bluetooth mesh is about a mile. In meshtastic, it can be several hundred miles.
