Help finding a combo ESP BLE Keyboard & Mouse Library (which compiles using ESP v3 framework on Arduino)

[cmcooper1971]

Hi Guys,

Your my last chance to find a working solution to finding an operational Arduino Keyboard and Mouse Combo BLE library for ESP32? I'm asking here, as the one below states that your library needs to be installed, which it is.

I have tried the following, but it will not compile, although I have followed the instructions and ensured your library is installed.

A-box1000
ESP32-NimBLE-Combo

If I use the following individual libraries, such as these two, I can connect and control my PC using an ESP successfully.

wakwak-koba
ESP32-NimBLE-Mouse

wakwak-koba
ESP32-NimBLE-Keyboard

Any assistance would be welcome.

My working sketch is as follows:

#include <BleKeyboard.h>

BleKeyboard bleKeyboard("ESP32 Remote", "ESP32", 100);

// GPIO pins
const int BTN_SHUTTER = 33;  // Volume Up (Camera shutter / video toggle)
const int BTN_UP = 13;       // Mouse drag up
const int BTN_LEFT = 14;     // Mouse drag left
const int BTN_RIGHT = 26;    // Mouse drag right
const int BTN_DOWN = 27;     // Mouse drag down

// Track last states
bool shutterPressed = false;
bool upPressed = false;
bool leftPressed = false;
bool rightPressed = false;
bool downPressed = false;

void setup() {
  Serial.begin(115200);
  Serial.println("Starting BLE keyboard...");

  pinMode(BTN_SHUTTER, INPUT_PULLUP);
  pinMode(BTN_UP, INPUT_PULLUP);
  pinMode(BTN_LEFT, INPUT_PULLUP);
  pinMode(BTN_RIGHT, INPUT_PULLUP);
  pinMode(BTN_DOWN, INPUT_PULLUP);

  bleKeyboard.begin();
}

void loop() {
  if (bleKeyboard.isConnected()) {

    // --- Shutter ---
    if (digitalRead(BTN_SHUTTER) == LOW) {
      if (!shutterPressed) {
        shutterPressed = true;
        Serial.println("Shutter PRESSED");
        bleKeyboard.write(KEY_MEDIA_VOLUME_UP);
      }
    } else if (shutterPressed) {
      shutterPressed = false;
      Serial.println("Shutter RELEASED");
    }

    // --- Up ---
    if (digitalRead(BTN_UP) == LOW) {
      if (!upPressed) {
        upPressed = true;
        Serial.println("Up Arrow PRESSED");
        bleKeyboard.write(KEY_UP_ARROW);
      }
    } else if (upPressed) {
      upPressed = false;
      Serial.println("Up Arrow RELEASED");
    }

    // --- Left ---
    if (digitalRead(BTN_LEFT) == LOW) {
      if (!leftPressed) {
        leftPressed = true;
        Serial.println("Left Arrow PRESSED");
        bleKeyboard.write(KEY_LEFT_ARROW);
      }
    } else if (leftPressed) {
      leftPressed = false;
      Serial.println("Left Arrow RELEASED");
    }

     // --- Right ---
    if (digitalRead(BTN_RIGHT) == LOW) {
      if (!rightPressed) {
        rightPressed = true;
        Serial.println("Right Arrow PRESSED");
        bleKeyboard.write(KEY_RIGHT_ARROW);
      }
    } else if (rightPressed) {
      rightPressed = false;
      Serial.println("Right Arrow RELEASED");
    }

    // --- Down ---
    if (digitalRead(BTN_DOWN) == LOW) {
      if (!downPressed) {
        downPressed = true;
        Serial.println("Down Arrow PRESSED");
        bleKeyboard.write(KEY_DOWN_ARROW);
      }
    } else if (downPressed) {
      downPressed = false;
      Serial.println("Down Arrow RELEASED");
    }

//    bleKeyboard.releaseAll();
  }

  delay(10);
}

Thanks.

Looks like the combo library hasn't been updated in quite a while, the author will need to update it or someone needs to fork it and do the required updates.

Hi Ryan,

Thank you for replying and yes, I agree with you, but was hoping someone knew of one as my skills do not extend to converting it to the latest framework.
