The files you are looking at is the service interface for the GLS server. This means you have to look at the GLS profile specification to see how to implement this. But, yes. The first step is to add the discovery module so you can perform a service discovery of the gls services. The discovery procedure can be handled similar to what is done in the HRS client example. This means you have to register the GLS UUID&#39;s in the discovery module and handle the discovery events in the gls handler. Note that eventually you should also qualify your implementation using the Bluetooth SIG PTS tool.</p><div style="clear:both;"></div>
