| In this step, we will analyse the behaviour of the client. The client software is much more complex than the server. It is because the central device in many circumstances is a more powerful device than the peripheral. Some parts of the software are implemented as callback functions because they handle reactions on the data coming asynchronously from the server. The diagram presents the algorithm of the client and data coming from the server. | In this step, we will analyse the behaviour of the client.
