Both bricks run python and both bricks have Bluetooth. So I figured they should be able to talk. In this video, I show how the EV3 pushes around the SPIKE Prime hub using python commands over Bluetooth. I have been thinking about this since the launch of LEGO SPIKE Prime. Today I figured that raw REPL was the easiest.
