@a4c8 said in NES30 found but can't connect (details inside):
I can start emulationstation afterwards, configure the controller and run games, but after restart they aren't solid anymore and blink instead. I tried setting the mode to boot or background, as described, but with no change.
I get the same behaviour with another model, they don't re-pair automatically if you restart RetroPie without shutting them down first. If you restart RetroPie, shutdown the controller and then start it up again, they should re-pair and the light will turn solid.
