Changing the mode is a bit of a pain. I find that mine takes holding the button for about 7 or 8 seconds, then when you release you don’t know for sure which mode it will jump to.
What happens to me is the gamepad starts up in Android mode (LEDs 3&4). To get it back to Xinput mode (LEDs 1&2) can take a couple tries but eventually I get there. That’s OK once you get to the correct mode. But I find mine will drop back to Android mode sometimes when I go to wake it up. The gamepad goes into sleep mode after about 10 minutes of inactivity. You then have to push the mode button to wake it up. Mine will sometimes come on in Xinput mode (which is the desired mode for the Onefinity), but sometimes it will start back up in Android like it does when I first power up the CNC.
I haven’t figured out a way to keep it in the correct mode yet and I have emailed the manufacturer of the gamepad but not heard back from them yet. When I know more I will pass it on in this thread.
