I am trying to send hex or binary numbers through BLE UART, but it is taking only char value which is converted into ASCII value.

I am using Adafruit's Bluefruit micro device and Bluefruit LE apps.

```
Serial.print(F("[Recv] "));
Serial.println(ble.buffer);
BluetoothData=ble.buffer[0];
Serial.println(BluetoothData);

```

In the UART box I want to type only a hex number and receive it in the Ble.buffer of the Arduino only.
