Official PS3 controller dropping BT connection with BT dongle

juzzy

Hi,
I just bought a BT dongle (CSR8510) to try and reduce some lag on my PS3 controllers (one official other a clone).

Wierd thing is the official PS3 controller pairs but then drops BT immediately when I use the sixaxis driver.
If I use the ps3controller driver it works fine but using the ps3controller driver I cant connect my clone console (ps3controller driver does not seem to allow both official and clone at the same time.)

I had both controllers working fine with on board Bluetooth using the sixaxis driver.

So do not know why the external BT dongle would not work with sixaxis driver but will with PS3controller driver. And why only the official controller has issues and not the clone.

Any explanation or help?
I can add what ever logs you need.

I have tried the below referenced fix but no luck.

@juzzy Did you disable the onboard Bluetooth on the PI ?

juzzy

@mitu yep. Disabled it through /boot/config.txt

mitu

Maybe something similar to https://retropie.org.uk/forum/topic/24590/ ?
You say your controllers worked with the sixaxis driver, what changed since they were working ? New Pi/updated system ?

juzzy

@mitu thanks for the link. But unfortunately seems like a slightly different issue. But I will try changing the baud rate with the on-board BT and see if it fixes the lag (which lead to me trying a BT dongle).

Both controllers (official and clone) currently work with the sixaxis driver with on board BT.
I have done no upgrades recently either.
Its when I change to a BT dongle that the sixaxis driver does not work (but for some reason only on the official PS3 controller).

It works great with no input lag with the clone controller, BT dongle and sixaxis driver.
I notice a noticeable difference in lag and ghost inputs between on-board BT and the dongle.
Hence why I would love to get both controllers working with the dongle and sixaxis driver.

Just seems so strange that one controller (clone) works fine but then the official one does not.
and only when using a BT dongle
Whats the difference?

mitu

Have you tried clearing you existing Bluetooth pairings and re-pair the controllers again, after using the new BT dongle ?

juzzy

@mitu yep. removed the paired controllers from the registry and then re-paired. Official PS3 controller still drops the BT with the sixaxis driver. Works with the PS3controller driver.
I can send you system logs of what happens when I get home.

@mitu this is the system log of what happens trying to connect the official PS3 controller:

As you can see the bluetooth service completely drops out and restarts.
Then log of what happens paring the clone PS3 controller:

Pretty much the same until it comes to sixaxis-helper.sh

The logs don't show much.

What version of RetroPie/Raspbian are you using ? Add more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

@juzzy

What version of Raspbian is your installation running? You can see it on the main page of the RetroPie-Setup script.

The BlueZ <5.48 hack in the log is the reason why Bluetooth is restarting on your installation. When a BT profile that matches the name PLAYSTATION(R)3 Controller is found, it renames it to Sony PLAYSTATION(R)3 Controller and then restarts Bluetooth for the rename to take effect. This is a hack to ensure the BT profile matches the name of the USB device (with the Sony prefix) to avoid the need to set up separate mappings for the BT vs USB connection in EmulationStation and other applications.

The Bluetooth stack should only restart one time after you've initially paired, and then work normally for subsequent pairings. I've not tested the hack with a BT adapter dongle, so there may be unexpected behaviour causing problems.

If you're running on an image based on jessie, I highly recommend that you upgrade to a stretch-based image, as newer versions of BlueZ will set the same device name for BT as USB by default, which avoids the need for the aforementioned hack to be executed by the sixaxis-helper.sh script. If upgrading your image is too disruptive, installing custombluez or enabling third-party support in the sixaxis script's configuration page should upgrade your version of BlueZ to the newer version that uses the correct BT profile name to match the USB name by default.

@psyke83

Love this community. Thanks for a fast response @psyke83 & @mitu.

I ended up hacking your hack in sixaxis-helper.sh.
I basically disabled the whole restart and renaming section by commenting it out.

sixaxis_rename() {
    local bt_profile="/var/lib/bluetooth/${BLUETOOTH_MAC^^}/${SIXAXIS_MAC^^}/info"
    if [[ "$(grep -e "^Name=PLAYSTATION(R)3 Controller" -e "^Trusted=true" -c "$bt_profile" 2>/dev/null)" == "2" ]]; then
        echo "BlueZ <5.48 hack: renaming BT profile to make consistent with kernel module name"
        # systemctl stop bluetooth
        # sed 's/.*Name=PLAYSTATION(R)3 Controller.*/Name=Sony PLAYSTATION(R)3 Controller/' -i "$bt_profile"
        # systemctl start bluetooth
        exit 0
    fi
}

The controller paired then.
but like you stated I had to re-config the controller inputs (for BT vs USB).

Digging deeper I compared the two files under var/lib/bluetooth/${BLUETOOTH_MAC^^}/${SIXAXIS_MAC^^}/info for the On-board BT and the Dongle BT addresses.

The file for the on-board BT holds the changes to the renaming "Sony PLAYSTATION(R)3 Controller"
But for the BT dongle - on restart it must overwrite the file again with the old name "PLAYSTATION(R)3 Controller".

Anyway I have a fix that works for me.
