@BuZz I used the RetroPie-Setup script (on a blank Raspbian/Pi 3) to add Retroarch and setup the bluetooth on my 8bitdo SFC 30, and it always auto reconnects the pad whenever I turn it on. So I'm a little confused to read that it's not actually supposed to be doing that?

I've been using it this way since launch of the Pi3, just turning on my 8bitdo pad and having it auto reconnect every time I turn it on. I never turn the Pi off.

I went ahead and setup a fresh Pi . This time a Pi 1 with a bluetooth dongle. The only thing I did was download retropie-setup and pair my 8bitdo pad. It auto reconnects every time I turn it off and on this way too.

Perhaps the original poster has outdated firmware on their 8bitdo pad?

Edit: For reference I turn my pad on with Start + R

Could be related to firmware. On my keyboard it gets reconnected automatically also, but not on my "8Bitdo SFC30 GamePad Joystick". However I just pushed an update to the bluetooth module in RetroPie-Setup where you can now choose between default bluetooth stack behaviour, connect once on boot (will try to connect to any registered devices), or background, which will launch on boot a script into the background which will try and connect every 10 seconds to any registered devices.

This should solve it for devices that don't connect automatically.

Odd, it's the '8Bitdo SFC30 GamePad Joystick' mode which has no problem reconnecting for me. Perhaps you're also on an older firmware? They improved auto reconnection in one update.

Although the switchable stack behaviour is definitely welcome.

I may well be - I've not updated the firmware. It affects other controllers too afaik.

Sorry for the delay in my response. I am using the 8Bitdo NES30 Pro with firmware 1.69. I had issues witht he remote not working but I found this post that allowed me to edit 8BitdoNES30ProJoystick.cfg and make it work.

This is a new remote and it is a beauty... only problem is the R1 button came broken so I am talking to the company to get a replacement. That being said I cannot attempt to try out the Start+R1 option so I have only ever paired with the simple Start option. Can you let me know what the difference is as I have read that is the correct pairing mode on many forums but it appears to be undocumented in the instructions.

As for the main question.

Thank you @Floob that basically solved it. I did have to edit it a bit. If I rebooted the system it would now take about two min before it would pair. So I usually turned it off/on to make it connect after the startup screen.

Here is the slightly modified code I used

#!/bin/bash
sudo bluetoothctl << EOF
 power on
 connect [MAC Address]
 exit
EOF

while (sleep 20)
do
 sudo bluetoothctl << EOF
  power on
  connect [MAC Address]
  exit
 EOF
done

Just a note to say that RetroPie now supports automatic re-connection of Bluetooth devices:

Wow! I'm watching it right now. I'm curious did my question help at all or was it just ironic timing on my part? I'm guessing I shouldn't follow the steps shown now that I have made everything work.
