Wiimote Still Not Connecting after Following Steps

[trigger_death]

Pi Model: Raspberry Pi 3 - Model B
Power Supply: CanaKit 5V 2.5A Raspberry Pi 3 Power Supply / Adapter / Charger
RetroPie Version: 4.1
Built From: Pre made SD image. (Boots on Micro SD, filesystem is on Flash Drive)
USB Devices: Keyboard, Flash Drive with filesystem on it

After following the steps on this guide here I still can't seem to get single Wiimote I configured to connect. Bluetooth sees it but it won't connect after setting up all the scripts and rules.

Steps and information about the steps I took.

• The RetroPie image is fresh from today. I did sudo ./retropie_setup.sh but for some reason it didn't ask me anything related to choose Binary-based installation.

• wminput has been installed

• nano /etc/udev/rules.d/wiimote.rules

  KERNEL=="uinput", MODE="0666"

• nano /home/pi/mywminput

  Classic-Controller

  Classic.Dpad.X = ABS_X
  Classic.Dpad.Y = ABS_Y
  Classic.LStick.X = ABS_HAT0X
  Classic.LStick.Y = ABS_HAT0Y
  Classic.RStick.X = ABS_HAT1X
  Classic.RStick.Y = ABS_HAT1Y
  Classic.A = BTN_A
  Classic.B = BTN_B
  Classic.X = BTN_X
  Classic.Y = BTN_Y
  Classic.Minus = BTN_SELECT
  Classic.Plus = BTN_START
  Classic.Home = BTN_MODE
  Classic.L = BTN_TL
  Classic.R = BTN_TR
  Classic.ZL = BTN_TL2
  Classic.ZR = BTN_TR2

  WiiMote

  Wiimote.A = BTN_A
  Wiimote.B = BTN_B
  Wiimote.Dpad.X = ABS_Y
  Wiimote.Dpad.Y = -ABS_X
  Wiimote.Minus = BTN_SELECT
  Wiimote.Plus = BTN_START
  Wiimote.Home = BTN_MODE
  Wiimote.1 = BTN_X
  Wiimote.2 = BTN_Y

  Nunchuk

  Nunchuk.C = BTN_C
  Nunchuk.Z = BTN_Z

  Plugin.led.Led1 = 1

• hcitool scan resulted in "00:1C:BE:F2:D8:64 Nintendo RVL-CNT-01"

• nano /home/pi/bin/attachwii.sh

  #!/bin/bash
  sleep 1 # Wait until Bluetooth services are fully initialized
  hcitool dev | grep hci >/dev/null
  if test $? -eq 0 ; then
  wminput -d -c /home/pi/mywminput 00:1C:BE:F2:D8:64 &
  else
  echo "Blue-tooth adapter not present!"
  exit 1
  fi

• I've executed chmod 775 /home/pi/bin/attachwii.sh and even added a sudo in front to see if that helps.

I've rebooted multiple times after all this and the wiimote still refuses to connect when ES is running after holding down 1+2 or the red sync button.

So I've figured out something.

if you run /home/pi/bin/attachwii.sh from the terminal the Wiimote can connect. So for some reason the executable isn't starting up like it should.

Does anyone have any insight onto why /home/pi/bin/attachwii.sh isn't running on startup?

[trigger_death]

I think I've finally solved this. I have no issues currently but I'm worried some might pop up. Anyways, here's what I did.

The RetroPie 3.x section in Register Wiimotes Before Emulationstation Starts actually has an unwritten counterpart for what to do in RetroPie 4.1 (4.x maybe?).

• Edit /etc/profile.d/10-retropie.sh.
• Follow the instructions for 3.x except put the line before if [ "tty" = "/dev/tty1" ]; then

The result should be this:

rebootWithoutWiimotes=0 /home/pi/bin/attachwii.sh
if [ "`tty`" = "/dev/tty1" ]; then
    bash "/opt/retropie/configs/all/autostart.sh"
fi

• Follow the instructions for My SSH terminal is unusable and giving me socket control errors! in the Known Issues section.
• This will make sure the terminal isn't flooded and fixes a problem where at least I couldn't access the RetroPie through SSH or SFTP.

The wminput lines in /home/pi/bin/attachwii.sh should now look like this:

    wminput -d -q -c  /home/pi/mywminput XX:XX:XX:XX:XX:XX > /dev/null 2>&1 &

After doing all that, order has been restored and the Wiimote pairs perfectly! I hope this helps anyone whose come across this. I'm not the best at writing wordy guide instructions so I'd recommend someone update the wiimote guide to have information for 4.1 (4.x maybe?).

@trigger_death it's a wiki. Anyone can add to it. Feel free.

[trigger_death]

Alright it's updated now. I'm going to assume the file has been changed from 10-emulationstation.sh to 10-retropie.sh starting in 4.0. I'm not entirely sure how to go about confirming that though.

[herb_fargus]

@trigger_death looks like it's there in the code:

https://github.com/RetroPie/RetroPie-Setup/blob/5cbf1c97e50bd67d67c19db1dbfc298d5d2e8afc/scriptmodules/supplementary/autostart.sh#L29

I'm not super familiar with the auto start scripts and I don't have a Wii mote to test but if you have it running then great!

Thanks for updating the docs so that others can benefit from it

[trigger_death]

Yup no problem. I also feel like the guide should be more specific in stating the SSH and terminal spam problem, other than in the issues section that may not be noticed. I'm just not sure what section to state it in.
