-# BLE API {#mainpage}
-
-The BLE module within mbed OS offers a high abstraction level for using
-Bluetooth Low Energy on multiple platforms.
-
-This documentation describes the internal structure of the mbed
-[BLE API](https://github.com/armmbed/ble). It was automatically generated from
-specially formatted comment blocks in BLE API's source code using Doxygen (see http://www.stack.nl/~dimitri/doxygen/ for more information on Doxygen).
-
-For getting started with BLE on mbed, check our [introduction
-page](https://docs.mbed.com/docs/ble-intros/en/latest/).
-
-For mbed OS examples using BLE, check [this
-repository](https://github.com/armmbed/ble-examples). For mbed-classic
-examples, please refer to [code under mbed.org](https://developer.mbed.org/teams/Bluetooth-Low-Energy/code/).

-## Supported Services
-
-Currently supported reference services include:
-
-* [Battery](@ref BatteryService)
-* [Device Firmware Update (DFU)](@ref DFUService)
-* [Device Information](@ref DeviceInformationService)
-* [Health Thermometer](@ref HealthThermometerService)
-* [Heart Rate](@ref HeartRateService)
-* [UART](@ref UARTService)
-* [UriBeacon](@ref URIBeaconConfigService)
-* [iBeacon](@ref iBeacon)
-
-The [documentation](https://docs.mbed.com/docs/ble-intros/en/latest/AdvSamples/Overview/)
-contains an overview on how to create new, application-specific services.
