# Mbed OS BLE services BLE services are available in the https://github.com/ARMmbed/mbed-os-experimental-ble-services repository. It's a community effort and contains services created by mbed-os team, our partners and mbed-os users. To use the services there add the repository to your project by adding a 'mbed-os-experimental-ble-services.lib' file containing the link to the repo like so: ``` https://github.com/ARMmbed/mbed-os-experimental-ble-services ``` Each BLE service is an Mbed OS library. To use it with new cmake based mbed-tools you will need to add the library to your link libraries for your application.
