RPi 3 B+ : tricky bluetooth problem with multiple PS3 controllers

mitu

@Bunnyface Please add more info about your system, as requested in https://retropie.org.uk/forum/topic/3/read-this-first.
Try removing the PS3 driver, reboot and then and install the customhidsonly driver from the RetroPie-Setup driver packages. This should make the PS3 controllers use the PI's bluetooth stack.

Sorry, I confess I read the rules quickly :(

• Pi Model or other hardware:
3 B+

• Power Supply used:
non-official with on/off switch

• RetroPie Version Used :
v4.4 (updated)

• Built From:
Pre made SD Image on RetroPie website

• Controller used:
PS3 controller (bluetooth) / fake SNES USB / wireless keyboard

I'm gonna try the customhidsonly driver, thank you very much for your help!

@Bunnyface If @mitu ttipps will for some reason not work then ...

Try reducing distance from your controller to Raspberry
Try to disable WiFi - this helps to extent signal strength, you can use this script to disable/enable Wifi

I faced also this problem and point 2 helps a bit but the solution for me was point 3

Buy a new BT adapter and put it to your Raspberry. Use dtoverlay=pi3-disable-bt in /boot/config.txt to disable internal BT module.

@cyperghost Thank you for your help!

I have tried @mitu's solution
but the standard bluetooth is not as stable as PS3 driver:
controllers don't connect directly, I have to plug them with USB to switch them on.

Moreover with pi's bluetooth stack;

one controller: works fine in EmulationStation and games
two controllers: work fine in EmulationStation but no response in games.

So I remove bluetooth devices and try to reconnect them but it fails now...

The distance of the controllers doesn't have any impact on the BT signal.
I will try to disable wifi.

@cyperghost, what BT adapter do you recommand?
And does this solution works flawlessly with 3-4 bluetooth controllers?
And can you add wired + bluetooth controllers at the same time?

Again, thanks for helping me guys!

Try turning off your wifi connection. That works fine for me

@Bunnyface Uff.. I used kind of this one ... very cheap but works best. As I mentioned before try to disable WiFi. You can do it manually with rfkill command or use my script. No need to worry you can enable/disable WiFi on the fly with this.

And does this solution works flawlessly with 3-4 bluetooth controllers?

Well I was in the same issue like you. With one controller I had lags from time to time (signal strength) but with 2 controllers it was no fun at all to play.
I can use that adapter with 2 controllers and they run flawless.

And can you add wired + bluetooth controllers at the same time?

Yes but I've no PS-controllers. I've two Bluetooth controllers from Snakebyte and some cheap wired pads for first setups. So I can't say if a wired PS-controller and a PS-BT-paired will work. But my two BT controllers and a wired pad works good.

I can confirm that 4 genuine ps3 controllers will work with retropie as I use it most weekends this way.
My setup works flawless, I play many of ps1 multi tap games, alot of micro machines for the mega drive (4 players) and also alot of mame beat'em ups 4 players.
You must disable WiFi for it to work properly, I worked this out a while back.
All I do is disable WiFi then install the ps3 driver.
After that all works perfect.
Before disabling WiFi my player 1 controller would work fine but the others would work intermittent.
Hope this helps.

@robmcc83 Nice feedback so indeed WiFi Switch Script is useful

@Bunnyface So try before buy

two controllers: work fine in EmulationStation but no response in games.

Just an idea, am not an expert but is the second controller configured correctly in retroarch, Im only suggesting this cause I had the same problem with a friends pi I set up for him

@robmcc83 @cyperghost @chicuelo @mitu

Thank you again guys! It works!

I have disabled wifi with f4 "rfkill block wifi"
and the two controllers work flawlessly!
The controller 1 is connected instantly without wifi!

@cyperghost, your script is awesome!
I don't need keyboard to switch off wifi now :)

Just one tiny "problem" with the wifi off:
now, at the start of the Pi,
there is a boot text (code) between the splashscreen and EmulationStation
which says "bluetooth stopped" during 10 seconds
(and other infos loading)

The only solution I see for this is to let the wifi on.
Having a nice boot with a cool splashscreen (and shorter boot)
And disable wifi with cyperghost's script.

But maybe somebody has the solution to skip the 10 seconds "bluetooth stopped" text?

@Bunnyface Try disabling the Wait for network boot option in the Raspbian tools, which you can start from the RetroPie system from a terminal with sudo raspi-config.

@mitu
Thank you for this tip!
The boot is faster disabling "wait for network"
and I don't have this text between splashscreen and emulation station.

So, for anybody having buggy bluetooth with 2 PS3 controllers
with a Raspberry Pi 3B+ and Retropie,
here is a solution:

disable wifi with [f4] "rfkill block wifi"
disable wifi with @cyperghost 's script:

Thanks again everyone,
we are going to have fun with my friends! :D
