@acris Thank you for your quick reply, but after entering the command "systemctl disable hciuart" the terminal responds to me as follows: "-sh: systemctl: command not found".
I don't know what I'm doing wrong, but this command does not work

I don't think it's possible to open the RetroArch menu without entering the game.
You can try to edit one of these files via LAN with Notepad ++ or via terminal with GNU nano:

• share/system/configs/retroarch/cores/retroarch-core-options.cfg

• share/system/configs/retroarch/retroarchcustom.cfg

The problem is finally solved - I bought a Trust YULA GXT 545 PS3/PC wireless controller with a dedicated dongle (set to D-input, buttons must be manually configured) for "Player 2" and everything works fine in RetroArch
Now the original PS3 controller (connected first on channel 1) works for "Player 1" and the game menu, and the Trust controller (connected second on channel 2) only works for "Player 2":

Yes, I tested it on a clean install.
I guess I have to use a third party controller for "Player 2"

In the bluetooth.tar file, both controllers have the same name & ID:

Maybe this is causing problems in RetroArch?

Hi guys,
I just installed Recalbox 7.1.1 on my RPi3b+ and I have the same problem as I did on Recalbox 6.1.1 with two PS3 controllers connected.
Both controllers are paired and connected via one usb bluetooth dongle (CSR 4.0).
The red PS3 controller (#0 SONY PLAYSTATION...OLLER) is connected first on channel 1 (LED number 1 is lit on it) and selected for "INPUT P1" in "CONTROLLERS SETTINGS".
The white PS3 controller (#1 SONY PLAYSTATION...OLLER) is connected second on channel 2 (LED number 2 is lit on it) and selected for "INPUT P2" in "CONTROLLERS SETTINGS".
Unfortunately, after running any RetroArch emulator (NES, SNES, PSX etc.), it turns out that their order is changed - the white PS3 controller on channel 2 controls the game menu and "Player 1", the red PS3 controller on channel 1 controls only "Player 2".
Can this be fixed somehow?

After some testing, I've realised that there is no need for disabling hci_uart in relalbox 6.1.1 because my USB bluetooth dongle works well on default settings. There is no need for disabling RPi's 3B+ onboard bt module too (by adding dtoverlay=pi3-disable-bt in config. txt).

My config:

• Raspberry Pi 3 B+ with latest version of Recalbox OS (onboard Bluetooth and WiFi disabled)
• Retroflag NESPi CASE+ with "safe shutdown" scripts installed
• FEASYCOM FSC-BP119 100m USB Bluetooth Dongle (CSR8510A10 chipset)
• 8BitDo SN30 pro controller (dinput)
• Verbatim 32GB USB 2.0 drive as an external storage
• Retroflag USB controller
• USB keyboard

The system reports "Y", but my 8BitDo SN30 pro does not connect automatically after rebooting. So I have to turn it off and turn it on again while the system is already loaded in "main menu" - this is the only way to reconnect
When the controller is connected it works well during emulation.

How about editing the /etc/bluetooth/main.conf file?

@elchhome I have the same problem with my 8BitDo SN30 pro ("after every reboot the pairing is lost").
I think You should open the terminal (press "F4" in Recalbox main menu, then press "ALT+F2", login: root, password: recalboxroot).

Then type in "bluetoothctl" then type the following commands :

agent on
default-agent
power on
scan on

Wait until bluetoothctl lists your device then:

pair AA:BB:CC:DD:EE:FF
connect AA:BB:CC:DD:EE:FF
trust AA:BB:CC:DD:EE:FF

Hello to all RecalBox enthusiasts.

I want to use an external USB Bluetooth dongle for my controller so I'm trying to disable onboard WiFi and Bluetooth on my RPi 3 B+ (I won't be using WiFi, so I want to turn it off too).

After logging into the terminal as a root (user: root, password: recalboxroot) I typed the following commands:

1. "mount -o remount, rw /boot" to remount partition on read-write
2. "nano /boot/config.txt" to edit the file located at /boot/config.txt

Then I've added to the config.txt file this overlays:

#Disable onboard WiFi and Bluetooth
dtoverlay=pi3-disable-bt
dtoverlay=pi3-disable-wifi

Then closed and saved the file with "CTRL + X", "Y" and "ENTER".

Now I have to disable hciuart but the command "sudo systemctl disable hciuart" doesn't work at all
After typing it in, the terminal shows me "-sh: sudo: command not found"

Is there any other way to disable hciuart?
Thank you in advance for any tips.
Regards.
