We thought of that. We don't have the right materials we'd need to do that experiment. A DS4 in a stainless steel container still has at least a 12m range when we tried that. As soon as it was out of range, it disconnected.
was it corded testing this?
No.
We didn't want to have to go there, but, it could be that we may need to go down the Bluetooth route. We can't really understand Sony's motivation on this one. We will investigate, but, as stated, if anyone sees anything out there about this particular issue (PS4 only talking wireless), please post to this thread.
