Gamecube bluetooth control doesn't work on dolphin

[RetromanX]

Hello, sorry for my bad English, it is not my native language so I used google translator.[url=<blockquote][/url]
I'm having a problem with controls on the Dolphin emulator, I bought a Gamecube bluetooth controller and the analog corners don't work properly, when I activate the diagonals, the characters are walking as if I'm moving the lever more smoothly, and they they don't run at all.
I tested several games and the result was the same.
I calibrated the control on windows, calibrated on the emulator, and the problem persisted.
So I decided to change it thinking that the problem could be control or some kind of incompatibility with the emulator.
I changed the controller and the problem continued, I decided to return it and bought another brand of bluetooth control from Gamecube, and the problem even contained changing the controller.
So I tested the con on native PC games and it worked perfectly. I also tested on the dolphin core at Retroarch and the operation was perfect.

Below are the images of the analog calibration:
