Support initialization of Bluetooth adapters, scanning and connecting Bluetooth devices, obtaining device services and features, monitoring feature value changes, reading and writing feature values, and disconnecting. By setting different listeners, it is possible to flexibly handle events such as changes in Bluetooth connection status, device discovery, service and feature discovery, which is suitable for WeChat mini program development scenarios that require data interaction with Bluetooth devices.
