Controller used: ps4 replica

sorry I'm late with this. Could this bluetooth connection problem be connected to the recent hack?

So, any clue why those things are happening?
The 8bitDo not being correctly usable, and the Switch pro regularly losing connection.

@mosi0815 thanks for the reply I will test that out soon. It makes perfect sense to me sounds simple enough. Is echo 1 to enable and echo 0 off? Nvm ill try it out tomorrow if I can.

@Adman1020 Yes, i have both a new and an old ps4 controller. The new one works with the blue tooth and you do not need any additional drivers, however I found it to be unreliable at times, when i used the ps4 controller one with a usb dongle it works perfectly all the time. Instead of dealing with issues from time to time, i decided to buy a dongle. You don't need one, it just works better. Just like the old ps4 controller will work with the ds4drv driver, they just work better with the USB receiver in my experience.

@darthlink Has anyone found a resolution to this? Just got a raspberry pi3 and having the same issues with the ps4 controller. How can I get the controller to automatically pair once the pi3 is turned on?
