 The characteristic defined in the example allows remote devices to read or write byte values. It is also possible to define characteristics which contain the text string.
 <code>
-BLECharacteristic textCharacteristic("19B10001-E8F2-537E-4F6C-D104768A1215",  BLERead | BLEWrite, "initial text");

-The number of characteristics in one service is limited to 512 by BLE specification. You can experiment on how many characteristics can be used in Arduino implementation.\\
+In the BLE specification, the maximal length of the characteristic's value is 512 bytes, the number of characteristics in one service is also limited to 512. You can experiment on how many characteristics can be used in Arduino implementation.\\
 The example program allows the remote device to control the state of the LED, so there is also a declaration of the "ledPin" variable.
