-To help you create your own BLE services, we have created this service template.
-The LED example demonstrates the use of a read-write characteristic to control a
-LED through a phone app.
-
-The template covers:
-
-* Setting up advertising and connection states.
-* Assigning UUIDs to the service and its characteristic.
-* Creating an input characteristic: read-write, boolean. This characteristic offers control of the LED.
-* Constructing a service class and adding it to the BLE stack.
-
-# Running the application
-
-## Requirements
-
-The sample application can be seen on any BLE scanner on a smartphone. If you don't have a scanner on your phone, please install :
-
-- [nRF Master Control Panel](https://play.google.com/store/apps/details?id=no.nordicsemi.android.mcp) for Android.
-
-- [LightBlue](https://itunes.apple.com/gb/app/lightblue-bluetooth-low-energy/id557428110?mt=8) for iPhone.
-
-Hardware requirements are in the [main readme](https://github.com/ARMmbed/mbed-os-example-ble/blob/master/README.md).
-
-*NOTE:* If you have more than a single mbed board (e.g. nrf51dk or mkit) you can
-run the BLE_LED and BLE_LEDBlinker at the same time. For more information please
-refer to the BLE_LEDBlinker demo.
-
-## Building instructions
-
-Building instructions for all samples are in the [main readme](https://github.com/ARMmbed/mbed-os-example-ble/blob/master/README.md).
-
-## Checking for success
-
-**Note:** Screens captures depicted below show what is expected from this example if the scanner used is *nRF Master Control Panel* version 4.0.5. If you encounter any difficulties consider trying another scanner or another version of nRF Master Control Panel. Alternative scanners may require reference to their manuals.
-
-
-1. Build the application and install it on your board as explained in the building instructions.
-1. Open the BLE scanner on your phone.
-
-1. Start a scan.

-
-1. Find your device; it should be named `LED`.

-
-    **figure 2** Scan results using nRF Master Control Panel 4.0.5
-
-1. Establish a connection with your device.

-    **figure 3**  How to establish a connection using Master Control Panel 4.0.5
-
-1. Discover the services and the characteristics on the device. The *LED service* has the UUID `0xA000` and includes the *LED state characteristic* which has the UUID `0xA001`. Depending on your scanner, non standard 16-bit UUID's can be displayed as 128-bit UUID's. If it is the case the following format will be used: `0000XXXX-0000-1000-8000-00805F9B34FB` where `XXXX` is the hexadecimal representation of the 16-bit UUID value.

-
-1. Open the write pannel of the *LED state* characteristic.
-
-    ![](img/write_characteristic.png)
-
-    **figure 5** How to read and write a characteristic value using Master Control Panel 4.0.5
-
-
-1. The characteristic accept a 1 byte value:

-
-    **figure 6** Write characteristic pannel using Master Control Panel 4.0.5
-
-    * `0x00`: LED ON

-
-        **figure 6** Write characteristic pannel to set the LED on using Master Control Panel 4.0.5
-
-
-    * `0x01`: LED OFF
-
-        ![](img/LED_OFF.png)
-
-        **figure 6** Write characteristic pannel to set the LED off using Master Control Panel 4.0.5
-
-
-1. Toggle the LED characteristic value and see the LED turn ON or turn OFF according to the value you set.
-
-If you can see the characteristic, and the LED is turned on/off as you toggle its value, the application is working properly.
