So it's a very simple Bluetooth connection.>In terms of what you can do with the connection, right now you can send Pokémon from Pokémon Go to Let's Go Pikachu and Eevee - and they don't go straight into your collection or your party, they enter into an area that's kind of like a Safari park type thing where you can see the Pokémon moving around in there, and you can actually go there and interact with them and catch them. But there are also some incentives to move a lot of the same Pokémon from Go - the same species - and there are some sort of mini games you can play if you do that.CONFIRMED: No trading, Let's Go is the happy ranch glue factory where your mass-transferred shitmon go, and if you want to send your legendaries over you have to catch them all over again
