Service and specification of Bluetooth low energy host tws mini wireless speaker

The most interesting transition from Bluetooth Classic to Bluetooth Low Energy is the architecture of services and specifications. Most of the specifications and protocols in classic Bluetooth define behavior and interaction guidelines. They are extremely complex and combine many different concepts. Among them, one of the biggest problems is that these specifications only define two types of devices, located at both ends of the link, and then define their respective behaviors separately. At first glance, this seems necessary, as if you have a mobile phone and a car (hands-free) kit, and we have to define how each works and how it interacts based on the specific application. Unfortunately, this also caused some trouble. www.bjbjaudio.com  <a style="opacity:0.0;color:#ffffff">tws mini wireless speaker</a>

The first problem is that the existing specifications do not clearly define the behavior of the devices themselves in the network. In other words, even though it appears that both devices define their own behavior, sometimes it's not clear what the device itself should do. This can lead to a lot of misunderstandings, where both devices mistakenly believe that the other should perform an action, and as a result the action is delayed. For example, the Hands-Free Profile (HFP) states that "Hands-Free Components (HF) and Audio Gateways (AG) can initiate an audio connection whenever necessary." The question arises, who should initiate the connection? Yes Hands-free components or audio gateways? What if they both initialize at the same time? It's an interactive dream. The obvious solution is for devices to define their behavior individually, making it clear what it should do. www.bjbjaudio.com    <a style="opacity:0.0;color:#ffffff">tws mini wireless speaker</a>

The second problem is that existing specifications can hardly be used for new scenarios that were not originally envisioned. Since the specification defines how two devices interact, and the devices are slightly different, the specification is difficult to use. This is a difficult problem even for the norm itself. For example, the hands-free specification defines a mobile phone and corresponding car kit, but in reality the most application combination is a mobile phone and a headset. The phone doesn't know whether it's talking to the car kit or the headset, and since the other party may be the car kit, the phone will continue to send UI status updates to the other device so that its updated interface can be displayed. This is a waste of power, because if the other party is a headset, it doesn't care that the signal strength drops from four bars to three bars. The obvious solution is to define the behavior of each device without knowing its capabilities. www.bjbjaudio.com  <a style="opacity:0.0;color:#ffffff">tws mini wireless speaker</a>
