8bitdo N30 Arcade driver and turbo function

[illando]

With the latest firmware upgrade (v4.10 ) 8bitdo finally fixed the Turbo function of the stick.
Everything works now, when the stick it's connected via USB, but when I try to connect it via Bluetooth the turbo function doesn't works correctly... It stops to repeat the button input after 3-4 times and after a pause of almost less than a second it start for another cycle of 3-4 inputs.

I noticed that there's a difference of driver used by Retropie to recognise the joystick depending on the type of connection:
USB >> 8Bitdo NES30 Arcade
Bluetooth >> szmy-power Ltd.Joypad

I tested the joystick with Retroarch on my PC, an it works always perfectly, via USB and also via Bluetooth, it’s always recognised as “8Bitdo NES30 Arcade”

I suspect there's something wrong with the "szmy-power Ltd. Joypad" driver in Retropie.
Can somebody explain me why Retropie needs to use 2 different drivers depending on the type of connection?
Any solution?

Thanks in advance

There is no dedicated 8bitdo driver, RetroPie is using the Linux native joystick drivers. I assume this is the name that the gampead sends to the system. Which mode are you starting and pairing the controller ? Try starting and pairing it when started in Android mode.

@mitu I'm paring using the Android mode (following the manual and selecting DIN PUT MODE via DINPUT/XINPUT switch, then pressing only the button START to power on the joystick and and press ing and hold PAIRING button for 2 seconds).
I used the same mode on my PC just to test in the same conditions.

Looking at the Retroarch yellow notifications, I can confirm the name the gamepad sends to the system is always "8Bitdo NES30 Arcade" on the PC side, and it doesn't change between USB or Bluetooth connection.

Using Retropie, there's this difference between USB or Bluetooth, and it's confirmed by the Retroarch yellow notifications.

@illando RA's notification about the name is actually based on the ES input configuration dialog when you first configured the gamepad. Did you pair the controller from the beginning in Android mode ? If not, then remove its configuration from ES and re-pair it and re-configure it again.

[illando]

@mitu Yes, I did the pairing process in Android mode since the beginning BUT with the old firmware. Maybe something is changed now. I’ll try with your suggestion!
To remove the ES configuration should I only need to delete the .cfg files from “configs/all/retroarch/autoconfig” or from "/opt/retropie/configs/all/retroarch-joypads"?

[mitu]

@illando To delete the configured controller, use the RetroPie setup script, go into the ES package and you'll have a 'remove controller config' option.

[illando]

@mitu No, I did it but the behaviour is still the same, as the 8bitdo N30 pro (with the difference that it doesn’t have the TURBO button).

USB >> 8Bitdo NES30 Arcade
Bluetooth >> szmy-power Ltd.Joypad
