 There is also Bluetooth specific information that you can set (optional):
-Instead of `BleKeyboard bleKeyboard;` you can do `BleKeyboard bleKeyboard("Bluetooth Device Name", "Bluetooth Device Manufacturer", 100);`.
-The third parameter is the initial battery level of your device. To adjust the battery level later on you can simply call e.g.  `bleKeyboard.setBatteryLevel(50)` (set battery level to 50%).
-By default the battery level will be set to 100%, the device name will be `ESP32 Bluetooth Keyboard` and the manufacturer will be `Espressif`.

+There is also a `setDelay` method to set a delay between each key event. E.g. `bleKeyboard.setDelay(10)` (10 milliseconds). The default is `8`.  
+This feature is meant to compensate for some applications and devices that can't handle fast input and will skip letters if too many keys are sent in a small time frame.

 ## Credits
 
-Credits to [chegewara](https://github.com/chegewara) and [the authors of the USB keyboard library](https://github.com/arduino-libraries/Keyboard/) as this project is heavily based on their work! Also, credits to [duke2421](https://github.com/T-vK/ESP32-BLE-Keyboard/issues/1) who helped a lot with testing, debugging and fixing the device descriptor!
