Ok, so I still encountered the problems from my last post where hci0 seems to be powered down, I reinstalled a fresh image onto the sd card, configured wifi and ssh, and installed xpadneo via the setup menu.

However even with the fresh install it now doesnt want to power on the bluetooth connector. I will leave it for today and try again tomorrow, could there be some configs or something that could carry over between installs? how can this bluetooth connector be so random.

Thank you for your help up until now though!

@mitu No, that doesn't work for me. That is my issue from the title: Device not available.

@gordonfreemanjr said in 8bitdo FC30 not pairing via Bluetooth:

@jplank Was that it?

Someone suggested I SSH into the retropie and go to bluetoothctl and then scan now. I did so and neither of the controllers showed up. I rebooted and tried again, same result. Then I tried one last time to load emulation station and pair the controllers - and it worked right away.

The thing is that I had about 15 tabs open with any youtube tutorial and help thread that I could find and I was trying anything I could find. For me, it wasn't that I changed setting X and then it suddenly started working. I "think" the last setting I changed was when mitu suggested changing the pairing mode. I changed it back to default and had to try a few more times to connect before it finally did. There might have been some resetting in there. All in all, I spent hours trying to get it to pair. I hope you manage to get yours fixed in less time. I hope that helps a bit. Good luck!

@mitu so i just mapped it in ES ( after re-enabling auto save) and then i had to quit ES and i did a system shutdown, performed a reboot and it is WORKING! so far, yes!! i think before, i wasn't exiting ES correctly and it kept remapping the r1 to only the start button as the "y" button. and it was showing up as a keyboard input. I REALLY appreciate your help. thank you!

You mean like Netplay ?

well, i don't know what i did differently, but i got it to work and i can't erase this thread...sorry

@phane said in Sixaxis dies after a few minutes, takes BT with it, requires reboot to reconnect:

What rate should I change (there are three in the file based on some if statements I don't understand) and what would be a good setting to reduce it to?

Change the 921600 value and halve it to 460800 (then 230400, 115200 etc.).

I should mention that in the configuration I only saw options for Gasia and Shanwan (and clone variants). My faux ps3 controller showed up as Gasia (when you "Configure Input" in EmulationStation), so I tried both Gasia options I saw in there. I think Gasia (Clone) was what ended up working for me. Lot of trial and error

I have managed to sort this out:

sudo systemctl stop bluetooth
sudo rm -rf /var/lib/bluetooth/*
sudo shutdown -r now

:D

@hairdyeguy said in Speeding up boot time and the necessary commands:

Tried it along side to disabeling bluetooth and rainbow splash screen + inserting the quiet flag to kernel. Booting time is now 28 seconds!
Are there more things you'd recommend?

The EmulationStation settings I mentioned in my first post - they should speed up dramatically the front-end startup.

Other services that are not strictly needed - raspi-config(?), hciuart (which you don't need if you disabled Bluetooth), rpi-eeprom-update (the Pi zero doesn't have an EEPROM).
You can also disable the swap service (dphys-swapfile) and test, but the Pi 0 has limited memory and swap may be useful if you want to install from source or run other things.

I'm not sure why the dev-mmcblk0p2.device takes so long, maybe the sdcard is not so fast (?).

There may be other - more radical - options

Forgot the post link. I tried most things listed here even though I’m using an Xbox one Bluetooth controller not a series controller.

Its always the last thing. Must have had some kind of hardware issue. reflashing my ssd has solved any issues. no idea what the original cause was. Some random little glitch is my guess. I was trying to avoid reflashing because of how far along I was in config, but backed it up and restoring it now that the controllers are all working. Thanks for attempting to help me h2805270, i appreciate it.

Im also having issues with the bluetooth and connecting 8BITDO controllers on RetroPie 4.7.1 on the raspberry pi 4.
I've tried about a dozen different tutorials.

When I go back to retropie 4.6, they connect straight away without any issues,

Any ideas?

@crush I was too. AFAIK if you have ps3controller installed and you install sixaxis, then ps3controllergets automatically uninstalled. But seems like installing ps3controller works perfectly after having installed sixaxis.

Update: I tried these instructions: https://raspberrypi.stackexchange.com/questions/53408/automatically-connect-trusted-bluetooth-speaker/76288#76288

Installed BaReinhard's repo and rebooted. I was able to connect to the AirPods when it launched back up and for a brief moment sound actually came through from youtube on the AirPods and I thought I may have fixed it, but then it cut out again after about two seconds. I'm getting the feeling that it connects and then gets disconnected almost immediately for some reason. Indeed, looking at bluetoothctl it seems to connect then disconnect to the devices immediately.

E.g. it will say:

sudo bluetoothctl
Agent registered
[CHG] Device D0:03:4B:ED:E5:20 Connected: yes
[CHG] Device D0:03:4B:ED:E5:20 Connected: no
[CHG] Device D0:03:4B:ED:E5:20 Connected: yes
[CHG] Device D0:03:4B:ED:E5:20 Connected: no

in quick succession, continuing on with this "yes/no" pattern. It does not seem able to maintain a connection.

Don't know if that sheds any light on the problem.

@mitu, greatly appreciate the reply and option. Thank-you!

It's probably a little over my head, but I'll dig in a bit.
