PS4 Controller Acting Erractically RP4

karhozat

Retropie ~~4.7.1~~ 4.8.2. PS4 controller connected via bluetooth to RP4.

Controller will drop out (controller doesn't disconnect, just won't register inputs) or random directional inputs will happen. This happens in both retropie menu/UI and retroarch games.

I have an 8bitdo adaptor on order but I'd really like to understand this issue. Any and all help appreciated, thank you.

@karhozat why are you using this pretty old version of retropie?
We are at 4.8.2., and there has been quite a lot of updates concerning Inputs & BT-Connection.
Is there a special reason you stay with this 2 year old version?
I recommend to update the whole system and try again (i am using 4 8BitDos and PS3/4-Pads myself without issues. All Pads without extra dongle/adapter by the way.)

@sirhenrythe5th Good call out. I'm actually using 4.8.2 on second look. I don't know where I got 4.7.1 from!

@karhozat looks like radio interference. Coming from your case blocking signals, other Bluetooth devices nearby, other strong radio interference nearby, a microwave oven cooking nearby. Too much stuff uses 2.4 ghz.
I use an 8bit do adapter myself, and I still get problems when I put the adapter in the back of my case. If I use a usb extension cable, the issues go away.

@lostless ah, you could be right. I was playing upstairs with no problems earlier but experienced same issues when I moved it back downstairs I experienced issues again. Now my PS5 won't Bluetooth connect with the PS5. Something weird is happening.

@karhozat if your wireless router next to the pi/ps5? that may be an issue. You might have to move it to a different location or change channels on the 2.4 GHz line.

@lostless Yep, the wireless router, PS5, pi, Nintendo Switch and smart TV are all within a couple meters of each other in the living room. Like I said, I didn't experience any issues using the pi upstairs. Thanks for your help here, I never would have considered that to be the issue.

I might just have to go wired when using the pi in the living room as I don't have an option to move the wireless router.
