Solved 4.1 bluetooth pairing persistency issue?

[valvolt]

I start them with R+Start, exactly as I did on the previous version(s) of Recalbox, and as described here: https://github.com/recalbox/recalbox-os/wiki/8bitdo-on-recalbox-(EN).

Just to make sure, I tried to use keyboard mode (mode 2) but unsurprisingly this failed as well. I also checked that using the stick in USB mode works perfectly.

How can I check what retroarch sees? Where does it (and other emulators) read info about configured pads? What is weird is that several emulators fail, could there be a mishap upon the saving of the pad configuration (e.g. at the end of the configuration step) ?

For info, I just configure up, down, left, right, A B X Y L1 R1 Start Select and Hotkey (on Select), leaving all the rest empty. This worked well in Recalbox 4.0.

Alternatively, does anyone reading this successfully use a 8bitdo on 4.1 or am I the only one so far?

@valvolt Hi,

Which 8bitdo pad do you have exactly ?

[Substring]

@valvolt I have the FC30 arcade stick, worked flawlessly.

@oyyodams quoting my post above I have one SNES30 (the one looking like a US pad with purple buttons) and one SFC30 (the one looking like a JP / EU pad with colored buttons). These are 'classic' pads (regular SNES pads, not the Pro version with the sticks). Same problem with both pads. They both worked well before v 4.1 when started with R+Start.

@Substring ok, so maybe that's a specific issue ?

[OyyoDams]

@valvolt ok sorry for my post, I didn't see your reply. About ths SFC30, there is an advanced documentation here.

I know you've already tried many things, but could you start the whole process again ?

1. Upgrade to the latest 8bitdo firmware
2. In ES, forget all your BT devices
3. Factory reset your SFC30: START for 8 seconds
4. Power it off if necessary, then turn it on. Hit Select for 3 seconds to enter pairing mode.
5. In ES, try to associate it again

[valvolt]

@OyyoDams Wow, I think that you nailed it !
I finally managed to get the SFC30 working after a firmware upgrade (my version was 2.67, since your URL stops at 2.62 I looked around - and found version 3.0 here: http://download.8bitdo.com/Firmware/GamePad/)

Everything worked like a charm: I could start the pad with Start (only), pair it, configure it and use it in a game.
I'm now doing the same with the SNES30, a priori I can use the same firmware. There is no reason this should fail.

So THANKS A LOT to both of you, @Substring and @OyyoDams for having taken the time to help me. I hope this post will help other users as well.

Keep up the excellent work !

@valvolt hey thanks for your feedback, I'm very happy for you!

Also thanks for the firmware link... 8bitdo have really good products but poor websites and documentations

Happy gaming

Hi all. I have been reading the post because I am having the same issue with a 8bitdo gamepad, in my case the zero one.

Recalbox recognize it but it can not be paired. I followed this wiki link:

https://github.com/recalbox/recalbox-os/wiki/8bitdo-on-recalbox-(EN)

and all the directions in this post, but when I select the device, I always receive the same message, it can not be paired.

@valvolt, the link you shared with the firmware, does it work for 8bitdo zero?

Thank you guys

@pmroyo Hi, all firmwares seem to be there: http://download.8bitdo.com/Firmware/

But be carefull, not sure which one can be used with this pad.

@pmroyo @OyyoDams 8bitdo zero cannot be flashed, so you can’t upgrade the firmware.

@pmroyo Don’t forget that you need to start you gamepad with the combo “START+R”, and to reboot the pairing record of it as stated on the wiki page you linked.

[pmroyo]

Thank you guys, I forgot about the firmware then.

Talking about the process, I follow these steps:
1- Remove all paired devices in recalbox
2- Press select in the gamepad for 8 seconds to reset it
3- Switch it on with Start+R
4- Press select for 3 seconds to access pairing mode
5- Then, search for new devices in recalbox

I have tried also without step 4 , but the result is the same, recalbox find the gamepad but it can not be paired.
As the main gamepad, I am using a Gamesir T1S with a wifi dongle, could it be interfering into the process?

[valvolt]

@pmroyo did you try with the 'manual' way ?
https://github.com/recalbox/recalbox-os/wiki/Connect-bluetooth-controller-manually-(EN)
What works and what does not?

[Substring]

@pmroyo you(d better reboot once you forgot paired devices. It sometimes confuses the bluetooth stack
