Combine Media Key support (jakern) and Fix mouse reconnection (blackketter)

[Hard-n-Soft]

There are two similar librarys from jakern and you, blackketter.
First support mouse reconnection but no Media Key, the other one from you
supports Media Key, but this library has problems with the mouse reconnection?

I tried to combine the functionallity by comparing source code.

I added in BleComboKeyboard.cpp

bleKeyboardInstance->connectionStatus->inputMediaKeys = bleKeyboardInstance->inputMediaKeys;

and in BleConnectionStatus.h

BLECharacteristic* inputMediaKeys;

and changed BleConnectionStatus.cpp

#include "BleConnectionStatus.h"

BleConnectionStatus::BleConnectionStatus(void) {
}

void BleConnectionStatus::onConnect(BLEServer* pServer)
{
  this->connected = true;

  BLE2902* desc = (BLE2902*)this->inputKeyboard->getDescriptorByUUID(BLEUUID((uint16_t)0x2902));
  desc->setNotifications(true);

  desc = (BLE2902*)this->inputMouse->getDescriptorByUUID(BLEUUID((uint16_t)0x2902));
  desc->setNotifications(true);

  desc = (BLE2902*)this->inputMediaKeys->getDescriptorByUUID(BLEUUID((uint16_t)0x2902));
  desc->setNotifications(true);
}

void BleConnectionStatus::onDisconnect(BLEServer* pServer)
{
  this->connected = false;

  BLE2902* desc = (BLE2902*)this->inputKeyboard->getDescriptorByUUID(BLEUUID((uint16_t)0x2902));
  desc->setNotifications(false);

  desc = (BLE2902*)this->inputMouse->getDescriptorByUUID(BLEUUID((uint16_t)0x2902));
  desc->setNotifications(false);  

  desc = (BLE2902*)this->inputMediaKeys->getDescriptorByUUID(BLEUUID((uint16_t)0x2902));
  desc->setNotifications(false);
}

The function KEY_MEDIA_MUTE, KEY_MEDIA_PLAY_PAUSE, KEY_MEDIA_NEXT_TRACK are working as wanted. But when sending
Keyboard.write( KEY_MEDIA_VOLUME_UP ); or Keyboard.write( KEY_MEDIA_VOLUME_DOWN );
lead to blocking PC. I'm not able to switch from window to window by ALT+TAB after sending this commands. It takes a while for the PC to react normally again. Strange.

Is there an common solution possible, Best regards.

Very late, but i can't get writing media keys after restarting the esp. At least with KEY_MEDIA_MUTE

I guess this library unfortunately is not longer really maintained at all :/
