Hello I have been trying to make an esp32 based bluetooth gamepad that has 4 momentary push buttons and 2 joysticks. But I can't to get it to work with my MacBook. The main problem that I am facing is that the esp32 pairs with the MacBook but nothing gets registered neither the button presses nor the joystick movements. The code that is supposed to work is below. Thank you for any kind of help in advance.
#include <Arduino.h>
#include <BleGamepad.h>
//ABXY BUTTONS
#define X_BUTTON 23 // A
#define CIRCLE_BUTTON 22 // B
#define TRIANGLE_BUTTON 21 // Y
#define SQUARE_BUTTON 19 // X
//TRIGGERS

#define R2_BUTTON 0
#define L1_BUTTON 0
#define L2_BUTTON 0
//MENU BUTTONS
#define START_BUTTON 0
#define SELECT_BUTTON 0
#define PS_BUTTON 0
//JOYSTICKS BUTTONS
#define R3_BUTTON 0
