I just received my DJI RC2 Controller I ordered for my NEO Drone. Just for the heck of it I connected my Epson BT-40 Glasses to the USB-C connector on the controller to see if the RC2 would work with the BT-40, as I expected the BT-40's didn't work. The RC2 was already powered up when I connected the glasses, so I decided to power cycle the RC2 with the BT-40 Glasses already connected and VOLA!!! it WORKED. The Epson BT-40 Glasses work with the DJI RC2 as long as you connect the Glasses to the controller before it's powered up.
