So, details: Debian 10, ds4drv, original PS4 controller, works find with USB.
Bluetooth works for a while, but after a while the signal strength lessens for some reason and it becomes impossible to play with it.
I rather post this here than elsewhere because: STK has a large user base, people might have run into the same problem as me, I only use the gamepad for STK. I do suspect that this might be a result of poor configuration and not an actual bug in the driver itself. If I'm out of line for posting this here feel free to delete it.
I've checked out the STK site, the Github issues for STK and ds4drv, and searched the forums. I might just be lacking the search skills. If that is so I'd be grateful if you could point me in the right direction.
