因此，我一直在努力实现从速卖通获得的蓝牙指纹读取器。我已经花了两天的时间进行操作，目前处于可以连接和发送内容的阶段。但是我不知道如果没有适当的UUID和服务怎么办。这是外围设备信息

但是我看到只有4个字符的特征。据我所知，它们的格式为XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX。我已经在JAVA中获得了一些源代码，如果有人想看一下，我可以上载（我安装了它，它可以扫描指纹并将其BitMatrix返回给我。）（src java项目：{{ 3}}）

这是我在RN中使用的功能的代码。

    test(peripheral: { connected: any; id: string; }) {
        if (peripheral) {
            if (peripheral.connected) {
                BleManager.disconnect(peripheral.id);
            } else {
                BleManager.connect(peripheral.id).then(() => {
                    let peripherals = this.state.peripherals;
                    let p = peripherals.get(peripheral.id);
                    if (p) {
                        p.connected = true;
                        peripherals.set(peripheral.id,p);
                        this.setState({ peripherals });
                    }
                    console.log('Connected to ' + peripheral.id);


                    setTimeout(() => {
                        BleManager.retrieveServices(peripheral.id).then((peripheralInfo) => {
                            console.log(JSON.stringify(peripheralInfo))
                            var service = '49535343-6daa-4d02-abf6-19569aca69fe';
                            var crustCharacteristic = '49535343-fe7d-4ae5-8fa9-9fafd205e455';

                            setTimeout(() => {
                                BleManager.startNotification(peripheral.id,service,crustCharacteristic).then(() => {
                                    console.log('Started notification on ' + peripheral.id);
                                    setTimeout(() => {
                                        BleManager.write(peripheral.id,crustCharacteristic,[0]).then(() => {
                                            console.log('write succes');
                                        });

                                    },500);
                                }).catch((error) => {
                                    console.log('Notification error',error);
                                });
                            },200);
                        });

                    },900);
                }).catch((error) => {
                    console.log('Connection error',error);
                });
            }
        }
    }

有人有经验吗？我还得到一张表，该表指出我认为其中包含所有可能的命令（https://filebin.net/7jeo1o0lkgd8x2oy）。
